Fig. 6. Quantification of the sequential distribution of clonal progeny from the central DM sheet. (A,B) The proportion of total transfected cells localized in the myotome as PMPs, in dermis and in the ID at 24 (A) and 48 (B) hours after transfection. (C,D) Composition of the clones deriving from single DM progenitors at 24 and 48 hours after transfection, respectively. (E) Detailed distribution and size of clonal progeny (see text for details).
