Abstract

The invention relates to the field of cell engineering, and in particular relates to a culture medium and a culture method for inducing multipotent stem cells for directional differentiation of renal cells. The culture medium for inducing the multipotent stem cells for directional differentiation of the renal cellscomprises 10-15g / L of a DEME basal medium, 0.1-0.5mM of mannitol, 4-8U of heparin sodium, 1-1.5mM of L-glutamine, 0.5-0.85mM of sodium pyruvate, 0.15-0.2mM of beta-mercaptoethanol, 1-3mg / L of fibronectin, 27-39ng / mL of directional differentiation induction factors, and a serum replacement. The culture medium for inducing the multipotent stem cells for directional differentiation of the renal cells, provided by the invention, can effectively promote induction of the directional differentiation from the multipotent stem cells to the renal cells, and no fetal calf serum is added in the culture medium, thereby avoiding a risk of infection of animal pathogens.

Description

technical field [0001] The invention relates to the field of cell engineering, in particular to a culture medium and a culture method for inducing pluripotent stem cells to differentiate kidney cells. Background technique [0002] Chronic kidney disease is one of the common clinical diseases. According to the latest epidemiological survey, there are currently 120 million chronic kidney disease patients in my country, with a prevalence rate as high as 10.8%, and it is showing a growing trend year by year. Kidney transplantation is the most effective clinical treatment, but there are problems such as shortage of donors, allogeneic rejection and life-long administration of immunosuppressants. Therefore, finding seed cells with strong regeneration ability and no rejection becomes the key to solve this problem. At present, the cells used in regenerative medicine research mainly include adult stem cells and embryonic stem cells, but these two types of cells have certain disadvan...
