Abstract:
:The cells responsible for the long-term in vitro generation of murine mast cells have been examined. Sequential analysis of all colony types obtained from cultures of spleen or bone marrow cells showed that only colonies derived from multipotential cells (mixed-erythroid colonies) or mast cell progenitors, contained cells responsible for mast cell generation in liquid cultures. Primary colony growth and subsequent maintenance of mast cells in liquid cultures was dependent upon pokeweed mitogen-stimulated spleen cell-conditioned medium (SCM). Mixed-erythroid colonies from 14-day cultures of spleen cells had the greatest capacity for mast cell generation. Analysis by clone splitting and transfer to high (20%) and low (2.5%) concentrations of SCM showed that the concentration of SCM used in either the primary colony culture or subsequent liquid culture phase altered both the proliferative capacity of the mast cells generated and the frequency of mast cell progenitors within individual mixed-erythroid colonies. Thus, mixed-erythroid colonies stimulated with 2.5% SCM contained the highest proportion of mast cell progenitors (34% of colonies) and when stimulated with 20% SCM, approximately fourfold higher numbers of mast cells were produced at weekly intervals from liquid cultures maintained in 2.5% SCM compared to parallel liquid cultures containing 20% SCM. These studies confirm the hemopoietic origin of mast cells and demonstrate that a factor(s) in SCM is able to modulate their proliferative potential.
