Effect of TPO on the expansion of hematopoietic progenitors. Hematopoietic cells cocultured 7 days on GpE86-Mpl-R cells (d7) or cocultured 7 days with GpE86-Mpl-R cells and stimulated with TPO during 7 days in liquid culture (d7 + 7) were plated in methylcellulose or agar in the presence of IL-3 + EPO, SCM, or TPO. The results represent the number ± SEM of progenitors per 105 cells plated (n = 3).
