Niches of progenitor cells with non-muscle cell fates and the corresponding migratory paths, related to Figure 5 and 7

(A) Schematic diagram of niches of progenitor cells with non-muscle cell fates and corresponding migratory routes. Three niches revealed in this study locate at dorsal margin (i), lateral ventral margin (ii) and medial ventral margin (iii) of somite. (B-G’) Cell tracking reveals the niches and corresponding migratory routes. (B-C) Progenitor cells stemmed from dorsal margin (i) migrate dorsally and move into the interface between myotome and neural tube. (D-E) Progenitor cells stemmed from lateral ventral margin (ii) migrate ventrally. (F-G) Progenitor cells stemmed from medial ventral margin (iii) migrate to the interface between notochord and myotome. (B, D, F) Cell tracking based on time-lapse imaging. White lines denote to the boundary of myotome. (C, E, G) Cell tracking based on photo-conversion of Kaede at the dorsal and ventral margin. White short arrows label the corresponding non-muscle progenitors at 8 hours after photo-conversion.
