Four-factor human iPSCs are better than three-factor iPSCs for megakaryopoiesis, which is independent of hematopoietic colony potential. (A) Numbers of ESC- and iPSC-sac–like structures generated from 105 cells (n = 3, means ± SEM from three independent experiments). (B) Numbers of CD34+ hematopoietic progenitors within ESC- or iPSC-sacs yielded from 105 human ESCs or iPSCs (n = 3, means ± SEM). (C) Numbers of hematopoietic colonies derived from 105 human ESCs or iPSCs within sacs (n = 3, means ± SEM). (D and E) Numbers of CD42b (GPIbα)+ MKs derived from 105 hematopoietic progenitors within sacs on day 22 (D) and day 26 (E; n = 5, means ± SEM). (F) Representative flow cytometry dot plots for khES-3–, TkDN-4-M–, and TkDA3-4–derived MKs examined on day 24.
