To perform flow cytometry analysis and to sort BFU-E and CFU-E cells from primary human samples including BM, cord blood, and peripheral blood, we isolated CD45+ cells from mononuclear cells (MNC) derived by Ficoll density gradient separation, followed by positive selection using CD45 magnetic beads. |
Ab or appropriate isotype controls (all from BD Biosciences)were incubated for 30 minutes in the dark. Cells were washed twice with 40 mL phosphate-buffered saline/0.5% bovine serum albumin, resuspended in 5 mL phosphate-buffered saline/0.5% bovine serum albumin, and stained with the viability marker 7-AAD on ice for 10 minutes in the dark. |
The analysis was performed using BD FACSDiva. Sorting was performed using a MoFlo high-speed cell sorter (Beckman Coulter). The number of BFU-E or CFU-E cells in one million MNCs was quantitated. |

>20 × 105 disaggregated sphere cells were stained with a stem cell‐specific antibody panel and analysed on a BDTM LSR II flow cytometer. To a volume of 100 μL cell suspension, 5 μL antibody mix was added, mixed and incubated for 20 minutes at 4°C in the dark and washed twice with 250 μL DPBS or FACS buffer. |
