Fig. 1
Ventral midbrain expression of transcription factors Lmx1a and Lmx1b at early stage of development. Representative confocal stitched images of immunohistochemical staining of the transcription factors Lmx1a and Lmx1b in TH-positive neurons in midbrain coronal sections at E15.5 (a) and P1 (b). Although Lmx1a and Lmx1b are present in all mDA neurons, the staining intensity for Lmx1a and Lmx1b varies in mDA neurons. Scale bars: a, 200 µm and 10 µm for high-magnification inserts; b, 200 µm, and 20 µm for high-magnification inserts. SNpc, substantia nigra pars compacta; VTA, ventral tegmental area
