Figure 3. GABAergic r1 neurons express PITX2, EN1, and LHX1/5.
Double immunolabeling of E12.5 mouse brain tissues sectioned transversely at the level of r1 (orientation as in Figure 2A) reveals distinct patterns of overlap among GABA and several transcription factors. Insets in C–O are enlarged in C’–O’ and show double (solid arrow) or single (open arrow) labeled cells. Scale bar in A is 100 µm and applies to panels A–O. All images were taken using confocal microscopy.
