Collection Summary: | Peripheral blood mononucleated cells were obtained from blood by Percoll density purification and CD34+ hemopoietic progenitor cells were isolated by magnetic bead separation according to the manufacturer's instructions (Miltenyi Biotec). CD34+ cells were cultured in a three-stage protocol based on the methods of 2d. Initially cells were cultured at 37 °C in a humid atmosphere of 5% CO2 at a density of 1 x 104 cells/mL and then maintained in the range of 2-10 × 105 cells/mL in IMDM (LifeTech) containing 5% (v/v) AB Serum (Interstate Companies Laboratories), 10 μg/mL Insulin (Sigma), 3 U/mL heparin (Pfizer), 200 μg/mL Transferrin (Prospec), 3 U/mL EPO (Eprex). During stage one (days 0-8) this was supplemented with 10 ng/mL SCF (GenScript) and 1 ng/mL IL-3 (R&D systems); during stage two (days 8-11) with 10 ng/mL SCF and additional 800 μg/mL transferrin and stage 3 (days 11-18) with 3 U/mL EPO and additional 800 μg/mL transferrin. Cultured reticulocytes (cRetics) were filtered at day 18 using a PALL WBF leukocyte filter. Isogenic control red blood cells (RBCs) were retained from donor blood, washed in IMDM and stored in saline-adenine-glucose-mannitol solution (SAG-M) at 4°C prior to use. Before analysis, cells were washed and cultured overnight in stage 3-supplemented IMDM (as outlined above). |
