Problems solved by technology

Corneal donors generally come from corneal donors. On the one hand, the number of donors is limited. On the other hand, there is still an immune reaction after allogeneic corneal transplantation, and even donor rejection occurs, resulting in surgical failure.

Abstract

The invention provides eye stem cell culture fluid, and belongs to the technical field of biology. The eye stem cell culture fluid is prepared through mixing low-sugar type MEM culture mediums, fetalcalf serum, non-essential amino acids, blood vessel endothelium growth factors, growth hormone release inhibiting factors and platelet-derived proliferation factors. The eye stem cell culture fluid can enable eye stem cells to have high proliferation capacity and fibroblast disintegrating potential, and regeneration of eye cells is facilitated.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an ocular stem cell culture solution. Background technique [0002] Corneal trauma is a common disease in ophthalmology clinics, and it can even lead to blindness in severe cases. The normal corneal epithelialization process is completed by the regeneration and differentiation of stem cells in the basal layer of the limbal epithelium. Corneal injury leads to corneal epithelial defect, and the secondary inflammatory reaction will affect the proliferation and migration of stem cells, form pannus, aggravate corneal edema and scarring, corneal turbidity affects light transmission, and even cause corneal ulcers. Corneal transplantation is still the only reliable and effective treatment for clinical corneal blindness. Corneal donors generally come from corneal donors. On the one hand, the number of donors is limited. On the other hand, there is still an immune reaction after allogeneic k...
