Abstract
Human mast cells (HuMCs) are derived from CD34(+) pluripotent hematopoietic cells which are KIT (CD117)(+) and FcεRI(-), and lack lineage-specific surface markers. Bone marrow and peripheral blood are the two readily available sources for obtaining CD34(+) cells from which HuMCs can be cultured. CD34(+) cells are isolated and enriched by magnetic separation columns and stored under specific conditions until ready for use. Alternatively, enriched CD34(+) cells may be immediately cultured in serum-free culture media containing recombinant human (rh) stem cell factor (SCF), rhIL-6, and rhIL-3 (added only during the first week). Weekly hemidepletions and removal of adherent cells and/or debris enables the investigator to obtain HuMC cultures, identified by Wright-Giemsa and acidic toluidine blue stains, by 8-10 weeks.
