Semi-thin section of Chicken Somite
At HH-14, somite 20/21 is newly formed epithelial-walled spheroid. At HH-16 it possesses two compartments, the dorsal dermomyotome, which has retained its epithelial structure (Fig. 1A), and the ventral sclerotome, a mesenchymal structure. Cells in dermomyotome exhibit typical epithelial characteristics, resting on a basal lamina and possessing apico-basal polarity.
A) The somite has formed the dorsally located epithelial dermomyotome (dm) and the ventrally located mesenchymal sclerotome (sc) at HH-16.
B) At HH-20, the dermomyotome has undergone EMT to form myotome (m) and sub-ectodermal mesenchyme (sem)
(Scale bar = 150 μm).
