Vitreous concentration of neuroprotective growth factor in Group A (treated) and in Group B (controls). Brain-derived neurotrophic factor, ciliary-derived neurotrophic factor, basic fibroblast growth factor, glial-derived neurotrophic factor, and nerve growth factor are significant neuroprotective growth factors tested in the vitreous in both Group A and Group B. They were significantly higher (P < 0.05) in rats affected by diabetic retinopathy treated by human stem cell transplant compared with Group B controls.
