Fig. 2. Shh promotes neurite outgrowth from VT explants but inhibits neurite
outgrowth from DN explants. (A) Ventrotemporal (VT) and dorsonasal
(DN) explants grown in the presence of different Shh concentrations. Outgrowth
was visualised by staining with phalloidin. (B,C) Quantification
of neurite outgrowth from DN (B) and VT (C) explants. Bar graphs show the area
covered by neurites (in pixels). The number of explants analysed is indicated
above each bar. *P<0.05,
**P<0.01 (one-way ANOVA). Scale bar: 500 µm.
