StemSpan-ACF Erythroid Expansion Medium

Erythroid lineage expansion from hematopoietic stem and progenitor cells requires a defined, animal component-free culture environment to support research into red blood cell production, transfusion science, and disease modeling. This liquid medium is formulated for the ex vivo proliferation of erythroid progenitors derived from human CD34+ cells sourced from cord blood, peripheral blood, or bone marrow, enabling researchers to expand cells through successive stages of erythropoiesis while maintaining reproducibility across experiments.

Used in standard in vitro cell culture workflows, the medium supports both static culture dishes and stirred-tank bioreactor systems, accommodating small-volume research studies through to larger-scale process development. Its animal component-free formulation reduces variability introduced by serum or other animal-derived supplements, supporting standardized protocols for cell therapy development and hematopoietic research applications.

Supplied as a single bottle ready for use, the medium is intended for refrigerated storage to preserve component stability throughout the culture period. Researchers typically pair it with cytokine cocktails to drive erythroid commitment and maturation across multi-phase expansion protocols. The product is manufactured by STEMCELL Technologies as part of the StemSpan family of defined media for hematopoietic cell culture.
