This colony number was obtained by counting fresh BM cells (5 × 104) cultured in methylcellulose without IL-3 and Epo. The numbers in the control line indicate colony numbers of those of nuclear cell counts of BM in the control mice that were injected with PBS. The results represent the mean ± SE of triplicate samples.
