Problems solved by technology

[0013] Because the in vitro culture of tumor tissue cells is affected by many of the above factors, there is currently no systematic solution to the culture of tumor tissue cells and a suitable medium at home and abroad, and there is no commercially available medium and culture technology for tumor tissue culture. Therefore, it is necessary to develop an effective tumor living tissue in vitro culture system and corresponding culture methods.

Embodiment 1

[0028] Embodiment 1: Tumor living tissue in vitro culture system according to the present invention

[0029] The tumor living tissue in vitro culture system of the present invention adopts a supporting system that simulates the basement membrane structure in the body and the blood supply system of the tumor, and preferably adopts a highly water-absorbing filter paper coated with collagen supported by a scaffold.

[0030] The present invention prepares two kinds of culture fluids, the first one is tumor tissue specimen treatment liquid, which is used for the pre-treatment of tumor tissue culture; in conventional immersion culture.

[0031] The tumor tissue specimen treatment solution of the present invention is based on conventional RPMI1640 culture solution, and the following components are added: amphotericin 2ug / ml, penicillin 1000U / ml, streptomycin 1000ug / ml.

[0032] The special culture medium for tumor tissue culture of the present invention is based on 50% mixture of DM...

Embodiment 2

[0035] Embodiment 2: decontamination and anti-pollution effects of the tumor tissue specimen treatment liquid according to the present invention

[0036] The tumors of the gastrointestinal tract were used for pre-treatment of microtissue block culture, and fresh tumor tissues were taken. One group was treated with conventional RPMI1640 culture solution containing double antibodies, and the other group was treated with the tumor tissue specimen treatment solution of the present invention.

[0037] The results showed that in the group treated with conventional RPMI1640 culture solution containing double antibodies, 6 of 32 cases of gastric cancer were contaminated, and 13 of 47 cases of intestinal cancer were contaminated. However, only one case of intestinal cancer was contaminated in the samples treated with the tumor tissue sample processing solution of the present invention.

[0038] Conclusion: The decontamination and antifouling effects of the tumor tissue specimen treatme...

Embodiment 3

[0041] Example 3: Effects of Support System Culture and Conventional Immersion Culture in the Present Invention on the Growth and Survival of Tumor Microtissue Blocks

[0042] On the basis of Example 2, the treated tumor tissue pieces were cut into 0.5-1mm 3 Tumor micro-tissue pieces, one group was cultured with the support system of the present invention, and the other group was cultured by immersion in conventional methods.

[0043] Detect after cultivating for 5 days, the result shows: the survival and growth state of the tumor tissue cultured by the support system of the present invention is significantly better than soaking culture (Pfigure 1 ).

Abstract

The invention relates to a tumor living tissue in-vitro culture system and a corresponding tumor living tissue in-vitro culture method. The tumor living tissue in-vitro culture system comprises a support system for simulating an in-vivo basilemma structure and a blood supply system of tumor, a tumor tissue specimen treatment liquid which is a RPMI1640 culture liquid containing 2mu g / ml of amphotericin, 1000U / ml of penicillin and 1000mu g / ml of streptomycin, and a special culture medium for tumor tissue culture, wherein the culture medium contains 20mu g / L of bFGF (Basic Fibroblast Growth Factor), 20mu g / L of EGF (Epidermal Growth Factor), 10mu g / L of PDGF (Platelet Derived Growth Factor), 10mu g / L of HGF (Hepatocyte Growth Factor), 10mu g / L of IGF (Insulin-like Growth Factor), 10mu g / L of NRG1, 10mu g / L of VEGF (Vascular Endothelial Growth Factor), 5% of fetal calf serum as well as 500U / ml of penicillin and 500mu g / ml of streptomycin on the basis of a mixture solution containing 50 percent of DMEM (Dulbecco Modified Eagle Medium) and 50 percent of HamF 12. The invention provides a systematic solution scheme and an appropriate culture medium for the in-vitro culture of tumor tissue cells.

Description

technical field [0001] The invention relates to an in vitro culture system of tumor living tissue, in particular to a special in vitro culture solution for tumor living tissue, and also to a corresponding in vitro culture method for tumor living tissue. Background technique [0002] Studies have shown that different types of tumors have different biological characteristics; the same type of tumors have different biological characteristics in different individuals. In order to study the biological characteristics of individual tumor tissue cells, such as the sensitivity of tumor tissue cells to radiotherapy and chemotherapy, and provide evidence for the diagnosis and treatment of tumor patients, it is necessary to culture primary tumor tissue cells. [0003] Simulate the microenvironment in vivo [0004] First of all, the tumor cells leaving the human body often undergo anoikis due to changes in the way of nutrient absorption and the microenvironment in which they survive. ...
