Fig. 1. Expression of Math3 in the developing retina. In situ hybridization of Math3 in mouse retina. (A) At P1, the retina consists of the ganglion cell layer (GCL) and ventricular zone (VZ). Math3 is expressed in the ventricular zone. (B,C) At P4 and P7, the retina consists of three cellular layers. Math3 is expressed broadly in the inner nuclear layer (INL). (D,E) At P14 and adult, Math3 is expressed in the outer region of the INL. (F) The sense strand was used as a probe. No signal is observed. (G-I) At P7, Math3 is expressed by calbindin+ amacrine and horizontal cells. (J-L) At P7, Math3 is expressed by HPC1+ amacrine cells. (M-O) At P7, Math3 is expressed by NF+ horizontal cells. (P-R) At P14, Math3 is not expressed by HPC1+ amacrine cells. (S-U) At P14, Math3 is still expressed by NF+ horizontal cells. Scale bar: 25 µm.
