IUPUI biologists, growing human pluripotent stem cell-derived retinal ganglion cells in the lab, have developed a way to create more-mature models that better mimic the environment in the human retina. By introducing hPSC-RGCs to astrocytes, researchers can create cells that are more analogous to human RGCs and can be further used to study diseases such as glaucoma. These results are published online in Stem Cell Reports.
