[0134] The second solution sampling unit 500A can be connected to the second solution circulation unit 400A.

[0137] The second grid chamber 100A can be easily rotated by the second driving part 300A and can have a cylindrical shape or the like so that the decellularized target second xenogeneic organ tissue or the like can be placed and accommodated inside.
[0138] In addition, when the second grid chamber 100A has a quadrilateral shape, the xenogeneic organ tissue will be clamped or retained at the corner parts when the second grid chamber 100A rotates, resulting in uneven stirring of the xenogeneic organ tissue. Therefore, in order to stir the xenogeneic organ tissue evenly and efficiently, the second grid chamber 100A is constructed in a cylindrical shape or the like.
[0139] The second grid 101A can be arranged in a grid pattern on the second grid chamber 100A.

[0140] The second grid chamber 100A can be constructed as a small chamber that can accommodate at most less than 25 g of the decellularized target second xenogeneic organ.
[0141] In addition, the size of the second grid 101A can be set to be slightly smaller than the size of the second xenogeneic organ tissue to prevent the second xenogeneic organ tissue or the like accommodated in the second grid chamber 100A from leaking outside the second grid 101A during the decellularization process.

The second coolant inlet 205A is used to inject coolant into the space between the second outer tube 203A and the second inner tube 201A, and the second coolant outlet 206A is used to discharge the coolant to the outside of the second outer tube 203A.
[0151] The second reaction vessel 200A may have a second solution outlet 207A for the decellularization solution to flow out.

[0160] The second driving motor 320A may be composed of a magnetically controlled motor or the like, so as to be able to easily rotate the second rotating shaft 310A.
[0161] The second rotating shaft 310A may be arranged at the center of the upper end portion of the second cover 110A along the vertical direction ( Figure 1 the Y direction in) with respect to the upper end portion of the second cover 110A, and may be coupled to the second cover 110A by being coupled to the second bolt 301A or the like.
[0162] The second rotating shaft 310A may be rotated in the clockwise direction or the counterclockwise direction by the second driving motor 320A, so as to drive the second mesh chamber 100A to rotate to stir the second xenogeneic organ tissue accommodated in the second mesh chamber 100A, thereby guiding the second xenogeneic organ tissue to smoothly achieve decellularization under the action of the second decellularized solution injected into the second reaction vessel 200A.
[0163] When the second mesh chamber 100A is rotated and stirred at a set rotational speed (for example, 1 to 300 rpm), in order to prevent overload of the second driving motor 320A and prevent entanglement between xenogeneic organs, stirring may be alternately performed from the forward (clockwise direction) to the reverse (counterclockwise direction), and a pause time may be set in the middle.
[0164] The second solution circulation unit 400A may include a second circulation pipe 410A and a second delivery pump 420A.
[0165] The second circulation pipe 410A may be connected between a second circulation port (not shown) arranged on the second cover 210A and the second solution outlet 207A, for circulating the second decellularized solution in the second reaction vessel 200A.
[0166] In addition, the second transfer pump 420A can be installed on the second circulation pipe 410A to quantitatively transfer the second decellularized solution flowing out from the second solution outlet 207A.
[0167] The second circulation pipe 410A can be composed of a flexible pipe so that it can be easily stretched and contracted when the second cover 210A is lifted and lowered by the second lifting part 600A.

[0178] A second guide rod 630A may be coupled to the second support frame 30A. The second guide rod 630A is connected to the second support frame 30A through a second connection frame 31A and is used to guide the lifting of the second lifting rod 621A.
[0179] In addition, for ease of cleaning, the second reaction vessel 200A and the second support frame 20A may be configured to be movable and detachable. A second groove 11A for aligning the positions of the second reaction vessel 200A and the second cover 210A may be arranged on the upper end surface of the second base 10A.
[0180] A second elastic member 21A may be coupled to the upper end portion of the second support frame 20A. The second elastic member 21A is used to buffer the impact generated when the second cover 210A descends and seals the second reaction vessel 200A.
[0181] Next, with reference to Figure 1 and Figure 2 , the operation of the decellularization reaction device according to an embodiment of the present invention will be described.
[0182] First, prepare a first xenogeneic organ tissue to be decellularized and a first decellularization solution for performing a decellularization reaction with the first xenogeneic organ tissue, and prepare a second xenogeneic organ tissue to be decellularized and a second decellularization solution for performing a decellularization reaction with the second xenogeneic organ tissue.
[0183] Here, a case where the first xenogeneic organ is different from the second xenogeneic organ and the first decellularization solution is different from the second decellularization solution is taken as an example for description. However, it is also applicable in the case where the first xenogeneic organ is the same as the second xenogeneic organ or the first decellularization solution is the same as the second decellularization solution.
[0184] Next, a case where the first xenogeneic organ tissue and the first decellularization solution are injected into the first grid chamber 100 and the first reaction vessel 200 by using the first in-situ analysis application device RA1 is taken as an example for description. However, it is also applicable in the case where the second xenogeneic organ tissue and the second decellularization solution are injected into the second grid chamber 100A and the second reaction vessel 200A.
[0185] In order to inject the first xenogeneic organ tissue to be decellularized and the first decellularization solution into the first grid chamber 100 and the first reaction vessel 200 respectively, as Figure 1As shown, the first cover 110 is set to a state of being opened from the first grid chamber 100 , and the first cover 210 is set to a state of being opened from the first reaction container 200 .
[0186] In this state, after the first decellularization object first heterogeneous organ tissue is placed inside the first grid chamber 100 and the first decellularization solution is injected into the first reaction container 200, the upper end of the first grid chamber 100 is covered by the first cover 110, and then the first cover 110 is combined with the first grid chamber 100 using the buckle 111.
[0187] In addition, the first lifting rod 621 of the first lifting cylinder 620 of the first lifting unit 600 is retracted. Figure 2 As shown, the first lifting rod 621 descends a set length, and then the first cover 210 covers the upper part of the first reaction container 200, thereby sealing the first reaction container 200.
[0188] Thus, as the first cover 210 seals the first reaction container 200, the first grid chamber 100 is Figure 2 Inserted into the interior of the first reaction container 200 as shown.
[0189] In addition, although the above description describes the case where the first decellularized solution is directly injected into the first reaction container 200, it is not limited to this. As another method of injecting the first decellularized solution, the first decellularized solution can also be injected into the first reaction container 200 through a first injection port (not shown) connected to the first solution injection tube 220.
[0190] In addition, after the first decellularization solution is injected into the first reaction container 200 , the first driving motor 320 of the first driving unit 300 is started to rotate the first rotating shaft 310 clockwise or counterclockwise at a set speed, thereby rotating the first grid chamber 100 .
[0191] Thus, as the first grid chamber 100 rotates and stirs, the first heterogeneous organ tissue in the first grid chamber 100 is stirred and, at the same time, undergoes a decellularization reaction with the first decellularization solution in the first reaction container 200 .
[0192] At this time, since the first xenogeneic organ tissue is stirred under the rotation of the first grid chamber 100, and the first decellularized solution moves along the vertical direction from the first cover 210 to the inside of the first reaction container 200 through the first circulation pipe 410, the first xenogeneic organ tissue and the first decellularized solution are fully stirred, so that the first decellularized solution of uniform concentration can be obtained in real time.
[0193] In this state, the first transfer pump 420 is started to circulate the first decellularized solution undergoing the decellularization reaction in the first reaction vessel 200 through the first circulation pipe 410 at a set speed.
[0194] For the first decellularized solution that circulates from the first solution outlet 207 of the first reaction vessel 200 to the first cover 210 through the first circulation pipe 410, sampling is performed by controlling the first solution sampling pipe control valve 511 to the open state and extracting it using the first solution sampling pipe 510.
[0195] The first decellularized solution sampled by the first solution sampling pipe 510 is loaded into a first small container 520 such as a vial, and then various physical properties (e.g., absorbance (UV-Vis), conductivity, turbidity, etc.) of the first decellularized solution loaded into the first small container 520 are measured and analyzed.
[0196] In addition, by sampling and measuring the first decellularized solution with a uniform concentration, it is easy to analyze various physical properties (e.g., absorbance (UV-Vis), conductivity, and turbidity, etc.) of the first decellularized solution, so the progress of the decellularization process can be accurately grasped.
[0197] (Example)
[0198] Next, decellularization experiments on each part (left atrium / left ventricle / right atrium / right ventricle) of a porcine heart, which is an example of the first xenogeneic organ to be decellularized, will be described.
[0199] 1) As Figure 3 shown, the porcine heart tissue is cut by part (left atrium, left ventricle, right atrium, and right ventricle), and a pretreatment process such as removing blood vessels and impurities is performed.
[0200] 2) As Figure 3 shown, after putting each part of the tissue (up to 25 g) into the first grid chamber in the first reaction vessel, the first lid of the first grid chamber is closed. The tissue of each part of the porcine heart is in a state of being locally cut with scissors, etc. If the tissue of each part of the porcine heart is cut into a size smaller than the size of the first mesh hole of the first grid chamber, it may leak out and be lost outside the first grid during the decellularization process, so attention needs to be paid.
[0201] 3) In the case of the myocardium, the decellularized solutions injected into the first reaction vessel are ultrapure water for the first time, SDS aqueous solution, Triton-X aqueous solution, EtOH, PBS aqueous solution, etc., and their types are diverse. When considering the volume of the first reaction vessel and the immersion height of the first grid chamber, the injection volume of each solution is, for example, 600 ml.
[0202] First, in order to remove impurities from the myocardium and decellularize it, ultrapure water is injected into the first reaction vessel once.
[0203] 4) Then, pressurized gas (air) is applied to the first lifting cylinder to move the first cover at the upper end of the first reaction vessel downward along the vertical direction, thereby sealing the first cover and the first reaction vessel. At this time, for safety, the first groove is used to confirm whether the first reaction vessel and the first cover are in the correct positions.
[0204] 5) The rotation speed (stirring speed) of the first rotating shaft under the action of the first drive motor in the first drive unit can be set from 0 to 500 rpm. In the case of a porcine heart, it is set to 350 rpm. The first mesh chamber is rotated and stirred when set to rotate clockwise for 10 seconds, with a pause time of 8 seconds, and then counterclockwise for 10 seconds.
[0205] 6) Meanwhile, the decellularized solution inside the first reaction vessel is circulated along the vertical direction (i.e., from the lower part to the upper part of the first reaction vessel) by using a metering first delivery pump. At this time, the circulation speed of the first decellularized solution is set to, for example, 200 ml / min.
[0206] As a result, although local decellularization of the first xenogeneic organ tissue inside the first mesh chamber is carried out, the first decellularized solution in the first reaction vessel is fully stirred because it is circulated inside along the vertical direction by the first delivery pump and is stirred by the rotation of the first mesh chamber. Therefore, a first decellularized solution with a uniform concentration can be obtained in real time.
[0207] Thus, when sampling the first decellularized solution, it becomes easy to analyze the conductivity, turbidity, absorbance (UV-Vis), etc. of the first decellularized solution. Therefore, the progress of the decellularization process of the first decellularized solution can be accurately grasped in real time.
[0208] 7) Figure 4 It is a chart of the turbidity analysis results of the first decellularized solution using ultrapure water (DW) in the decellularization process of each tissue (left atrium, right atrium, left ventricle, and right ventricle) of the porcine heart, and a chart of the turbidity of each tissue analyzed over time in each decellularization process after performing a total of three ultrapure water processes [DW(1)-DW(2)-DW(3)].
[0209] As Figure 4 shown in (a) of , the increase in turbidity, that is, the color of the first decellularized solution becoming turbid over time means that the blood and impurities contained in the tissue are discharged from the tissue, and significant differences are shown in each tissue. For example, the turbidity in the case of the left atrium is much greater than that in the case of the right atrium.
[0210] In addition, although the turbidity increases over time, it shows a tendency that the rate of increase gradually flattens out.
[0211] After the DW(1) process is completed, all the solution in the reactor is drained as waste liquid, and as Figure 4 shown in (b) of [], the ultra-pure water process is further carried out twice. After the DW(3) process, the turbidity of all tissues for the final analysis is less than 30 NTU, and it is thus judged that almost most of the impurities have been removed.
[0212] 8) Figure 5 It is a graph showing the results of conductivity analysis of the first decellularization solution of ultra-pure water (DW) in the decellularization process of each tissue (left atrium, right atrium, left ventricle, and right ventricle) of the porcine heart.
[0213] This is a graph analyzing the conductivity of each tissue over time in each decellularization process after a total of three ultra-pure water processes [DW(1)-DW(2)-DW(3)] are carried out.
[0214] In Figure 5 (a) of [], in the case of 3 minutes which is the earliest data, a very high conductivity was observed because the first decellularization solution in the first reaction vessel was not evenly mixed, but it became a stable state over time.
[0215] As Figure 5 shown in (b) of [], in the case of carrying out the DW(2)-DW(3) processes, the conductivity shown is greatly reduced as well as the turbidity, and it can thus be judged that almost most of the impurities have been removed.
[0216] 9) One revelation that can be obtained from the analysis results of the turbidity and conductivity of each tissue of the myocardium is that a high turbidity does not necessarily mean a high conductivity.
[0217] For example, although the left atrium has the highest turbidity, the conductivity of the left atrium is 280 uS / cm which is the lowest, while the conductivity of the left ventricle is about 670 uS / cm, far higher than the conductivity of the left atrium.
[0218] The correlation between turbidity and conductivity is related to the first decellularization solution (substance) of the first xenogeneic organ tissue, so subsequent related research is needed.
[0219] 10) Figure 6It is the analysis result chart of the absorbance (UV-Vis) of the first decellularized solution of the left ventricle using ultrapure water (DW) in the decellularization process of various tissues (left atrium, right atrium, left ventricle, and right ventricle) of porcine myocardium, and the chart of the absorbance (UV-Vis) of each tissue analyzed by time in each decellularization process after performing a total of three ultrapure water processes [DW(1)-DW(2)-DW(3)].
[0220] Figure 6 (a1) is the analysis result of the absorbance (UV-Vis) by time, Figure 6 (a2) is the graph representing the area (integral value) of these peaks using a chart.
[0221] Similar to the analysis results of turbidity and conductivity, although the peak area (PeakArea) increases over time, it shows a tendency that the increase rate gradually flattens out.
[0222] Figure 6 (b1) is the graph obtained by plotting (Plotting) the final data in each of the three ultrapure water decellularization processes, Figure 6 (b2) is the graph representing the area of these peaks (Area of Peak) using a chart.
[0223] As Figure 6 shown in (b1), the absorbance (UV-Vis) results decrease significantly as the process progresses, which means that it gradually approximates the intensity of the reference ultrapure aqueous solution set using the baseline (Baseline), and proves that the decellularization using ultrapure water is basically completed.
[0224] Similar results to the above are also obtained in the case of tissues other than the left ventricle (left atrium, right atrium, and right ventricle).
[0225] 11) Figure 7 is the graph taken during the decellularization process of myocardial tissue using ultrapure water and various organic solvents. It can be confirmed that during the process carried out in the order of (a)-(b)-(c), the volume of the tissue becomes smaller and its color also turns white.
[0226] (Test results of performance, etc.)
[0227] When evaluating the quality of the bioink of the first xenogeneic organ tissue after decellularization, the most basic item is biochemical assay. This test quantitatively represents the content of DNA, collagen, and GAGs in the tissue.
[0228] Table 1 shows the results of analyzing the DNA content of various tissues of a porcine heart after decellularization.
[0229] Since the DNA content of each tissue is different, the general criterion for determining that decellularization has proceeded well is that the DNA content in the tissue is less than 50 ng / mg.
[0230] As shown in Table 1, the DNA content of all tissues (left atrium, right atrium, left ventricle, and right ventricle) meets the above criteria, so it can be judged that decellularization has proceeded well.
[0231] [Table 1]
[0232] Left atrium Right atrium Left ventricle Right ventricle 8.2 ng / mg 6.7 ng / mg 7.5 ng / mg 6.2 ng / mg
[0233] If collagen and GAGs (glycosaminoglycans) are removed while discharging DNA, the physical properties of the bioink are poor. Therefore, it is necessary to analyze GAGs and collagen to confirm whether these two substances are well-preserved in the tissue. As shown in Tables 2 and 3, it can be confirmed that a large amount of GAGs and collagen are well-preserved.
[0234] [Table 2]
[0235] Left atrium Right atrium Left ventricle Right ventricle 1.7 μg / mg 2.1 μg / mg 1.6 μg / mg 1.5 μg / mg
[0236] [Table 3]
[0237] Left atrium Right atrium Left ventricle Right ventricle 53.2 μg / mg 63.1 μg / mg 30.3 μg / mg 30.1 μg / mg
[0238] From the above results, it can be seen that after decellularization of multiple varieties and small quantities of xenogeneic organs using the dual-machine system of the first and second dislodgment analysis application devices, the DNA content of the left atrium, right atrium, left ventricle, and right ventricle tissues has been reduced to an extremely low level, and collagen and GAGs in the tissue have also been very well-preserved. Thus, it can be known that high-quality bioink materials are efficiently produced.
