Identification of myeloid precursors in the 8 dpc YS. (A) Fractionation of 8 dpc YS using CD45 and c-Kit markers allows the discrimination of 3 subsets for further in vitro potential analysis. The percentage and absolute number per YS appear near the sorting gates. (B) Kinetics of macrophage-restricted (▪) and erythromyeloid precursors [□] in the YS from 2S to 8S, obtained by limiting-dilution experiments. Regression curves show that Mp (straight line) appear before EMp (dotted line).
