Figure 5From: Axon-bearing and axon-less horizontal cell subtypes are generated consecutively during chick retinal development from progenitors that are sensitive to follistatinHorizontal cells are not affected by apoptosis. (A-F): Stage 21 (A), 24 (B), 27 (C), 29 (D), 31 (E) and 35 (F) retinas stained for TUNEL (green) and Prox1 (red) reveal no overlap between the two signals. Scale bars: 20 μm (B and F are valid for A-B and E-F).Back to article page
