Patent ID: 12012611

Abstract:
A serum-free complete medium for inducing differentiation of a mesenchymal stem cell to a corneal epithelial cell in the field of differentiation induction of stem cells, prepared by the following method: uniformly mixing the serum-free complete medium, containing 5-10 μmol of resveratrol, 2-4 μmol of icariin, 1-3 nmol of aspirin, 1-3 nmol of parathyroid hormone, 5-10 nmol of hydrocortisone, 1-3 mg of rapamycin, 2-10 μg of testosterone, 2-10 μg of EPO, 2-10 μg of LIF and the balance of a corneal epithelial cell serum-free medium in per 1 L; and then performing sterilization by filtration. The disclosure uses resveratrol and icariin in combination with aspirin, parathyroid hormone, hydrocortisone, rapamycin, testosterone and growth factors to cooperatively induce directional differentiation, uses nontoxic induction components, is high in induction efficiency and short in induction time, and achieves high induced corneal epithelial cell activity, no cell transplantation rejection, no ethical problem and high safety.
