Low-oxygen and knock-out serum maintain stemness in human retinal progenitor cells

Using stem and progenitor cells to treat retinal disorders holds great promise. Using defined culture conditions to maintain the desires phenotype is of utmost clinical importance. We cultured human retinal progenitor cells (hRPCs) in different conditions: such as normoxia (20% oxygen), and hypoxia (5% oxygen) with and without knock-out serum replacement (KOSR) to evaluate its effect on these cells. KOSR is known nutrient supplement often used...
