Distribution of the total population of cultured CB cells in different phases of the cell cycle.
CD34+ CB cells were cultured for 5 days in serum-free medium containing TPO (1day) and FL + SF + IL-3 + IL-6 + G-CSF (4 days) and then stained with Hst and Py and analyzed by FACS using the gates shown. A representative profile is shown in panel A. Corresponding FACS profiles are also shown for the total cultured CB cells (B) and the isolated G0/G1 (C) and S/G2/M (D) fractions after restaining of the fixed cells with PI.
