Effects of IL-3 and IL-11 on the “proliferation history” of Lin−Sca-1+c-kit+cells cultured in the presence of KL+FL+MGDF.
CFSE-stained LSK cells were cultured in serum-free medium in the presence of the indicated growth factors. At the indicated time points, cells were analyzed by flow cytometry to determine their proliferation history. In each histogram, the number of cell divisions is indicated. Results are from 1 of 3 representative experiments.
