Figure 4. Schisis cavity measurements after injection of constitutive MSCs and inducible MSCs. A–C: Spidergrams of three post-injection time points comparing the schisis area in the four quadrants of the retina of the five different groups (untreated, vehicle-treated, untransfected mesenchymal stem cells [MSCs], constitutive MSCs, and inducible MSCs). D: The total schisis area from all four quadrants was calculated and compared among the groups at all three time points. Data are presented as mean ± standard error of the mean (SEM). IP = inferior peripheral; IC = inferior central; ONH = optic nerve head; SC = superior central; SP = superior peripheral. *p<0.05 (n = 6).
