The present invention belongs to the field of biomedicine, and relates to an inducer for inducing a mesenchymal stem cell to differentiate into an islet cell. An inducer for inducing a mesenchymal stem cell to differentiate into an islet cell consisted of the following components: GLP-1, parathyroid hormone, paracetamol, rapamycin, icariin, trametinib, EPO and VEGF. Each component in a inducer for inducing a mesenchymal stem cell to differentiate into an islet cell of the present invention is safe and non-toxic, requiring fewer steps and short time to induce differentiation, with high induction efficiency.

Inducer for inducing a mesenchymal stem cell to differentiate into an islet cell

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.
