Fig. 4From: The emergence of mesencephalic trigeminal neuronsInhibition of BMP signalling via in ovo electroporation of the dorsal midbrain. a. Representative high magnification image of Smad6-IRES-GFP electroporated cells. Thin arrows, typical MTN neurons. Scale bar, 25 μm (n = 8). b. Transverse cryosection of a Smad6-IRES-GFP electroporated midbrain. Arrowhead denotes the position of the dorsal midline. Thin arrows, typical MTN neurons. Scale bar, 20 μmBack to article page
