Abstract

The invention discloses a method for preparing a precursor cell of a retinal ganglion sample. In the method, the co-culture and / or mixed co-culture of a Transwell layered co-culture system is carried out on bone mesenchymal stem cells and the precursor cell of the retinal ganglion of a rat with gestational age of 13 to 14 days, thereby inducing to prepare the precursor cell of the retinal ganglion sample. The method is simple and easy to be carried out, has high inducing efficiency, does not need to transfer a foreign gene and has the advantages of safety and practicability.

Description

technical field [0001] The present invention relates to cell differentiation, in particular to a method for preparing retinal ganglion-like precursor cells. Background technique [0002] Mammalian retinal ganglion cells are difficult to regenerate after injury. Clinically, a variety of ophthalmic diseases, including glaucoma and ischemic optic neuropathy, can cause retinal ganglion cell damage, eventually leading to irreversible blindness. Research on stem cell replacement therapy has brought new hope for the treatment of such diseases. Retinal neural precursor / progenitor cells (RPCs) belong to immature retinal cells. In vitro and animal experiments have shown that they can integrate and differentiate into mature retinal neurons in the retina after transplanting them into the recipient retina. The visual function of the recipient animals was significantly restored. Studies have found that for a specific type of retinal nerve cells (such as rod cells), the corresponding pre...
