Embodiment 1
[0030] 1. Induction
[0031] (1) Take the P4 generation umbilical cord mesenchymal stem cells, when the cells adhere to the wall and grow to 80%-90% confluence, remove the original culture medium in the culture bottle, and take 10 mL 0.01M phosphate buffered saline (phosphate buffered saline, PBS) Gently add T 75 Wash in the culture bottle and discard the washing solution;
[0032] (2) Add 1.0 mL of 0.25% trypsin-0.01% ethylenediaminetetraacetic acid (ethylenediaminetetraacetates, EDTA) digestion solution, soak to cover the bottom of the bottle, observe under an inverted microscope that the cells are round and floating, add 1.0 mL of fetal bovine Serum suspended trypsinization;
[0033] (3) Add 10 mL of 0.01 M PBS to repeatedly blow and wash, and centrifuge at 1000 rpm for 5 minutes at room temperature; after discarding the supernatant, add 10 mL of DMEM / F-12 to resuspend the cells, 25 Inoculate 5×10 5 Personal umbilical cord mesenchymal stem cells;
