Fig. 7. (A) Lipofection of Xbh1 at late stages promotes ganglion cell fate. Counted cells were: n=401 cells from 23 retinae for GFP (orange) (sample section shown in B); n=564 cells from 36 retinae for Xbh1 (green) (C). The percent representation of each cell type was calculated as a weighted average±s.e.m. Asterisks represent significant differences between Xbh1 and GFP, as calculated by Student's t-test (^**P<0.01).
