Embodiment
[0083] The preparation method of the adipose tissue extracellular matrix of the present embodiment comprises the following steps:
[0084] Step 1: Pretreatment of Adipose Tissue
[0085] Take fresh adipose tissue, let it stand for 10min-15min, discard oil droplets, blood and swelling fluid, add PBS buffer solution to wash 3 times, and obtain pretreated adipose tissue (such as figure 1 shown).
[0086] Step 2: Freeze-Thaw Cycle
[0087] The pretreated adipose tissue obtained in step 1 was frozen at -80° C. for 2 hours, and then thawed at 37° C.; the above freezing and thawing process was performed 3 times in total to obtain the adipose tissue after freeze-thawing treatment.
[0088] Step 3: Broken
[0089] The adipose tissue obtained in step 2 after freezing and thawing is broken into a chylus shape, and many ways can be used for breaking, such as mortar method, smashing method, oscillation method, stirring method, homogenization method, temperature difference method, pressu...
