Figure 4. Pax6 is expressed in a subpopulation of tau-GFP heavily labeled LCS in DTy54 transgenic mouse line at both E12.5 and E15.5.

(A) Pax6 is expressed in the tau-GFP labeled LCS cells at E12.5 (arrows). (B) Higher magnification of boxed area in A revealed that at the ventricular zone of the PSPB, tau-GFP heavily expressing cells are located adjacent to the Pax6 positive cell populations, along with a small subset of cells expressing both tau-GFP and Pax6 (arrows). (C) Pax6 is expressed in the tau-GFP labeled LCS cells at E15.5 (arrows). (D) Higher magnification of boxed area in C further revealed that a subset of tau-GFP labeled LCS cells also express Pax6 (arrows). n=10 DTy54 embryos.
