An analysis was made of some of the processes involved in the stimulation by colony stimulating factor (CSF) of cluster and colony formation by mouse bone marrow cells in agar cultures in vitro. Colony formation was shown to be related to the concentration and not the total amount of CSF. The concentration of CSF determined the rate of new cluster initiation in cultures and the rate of growth of individual clusters. Colony growth depleted the medium of CSF suggesting that colony cells may utilise CSF during proliferation. Bone marrow cells incubated in agar in the absence of CSF rapidly died or lost their capacity to proliferate and form clusters or colonies. CSF appears (a) to be necessary for survival of cluster-and colony-forming cells or for survival of their proliferative potential, (b) to shorten the lag period before individual cells commence proliferation and (c) to increase the growth rate of individual clusters and colonies.read more

The viability of mononuclear phagocytes in vitro is diminished by the interaction of cells with serum proteins bound to the culture substratum.
TL;DR: The results indicate that serum proteins bound to the culture substratum exert a significant influence on the viability of adherent mononuclear phagocytes in vitro and on the requirement of cells for CSF-1 in order to survive.

TL;DR: The data demonstrate that CSA elaboration was maximal 24 h post‐VLB, corresponding to the nadir of bone marrow GM‐CFC, and 6 h after splenic reached a minimum.

Regulation of human endometrial stromal decidualization by macrophage colony-stimulating factor.
TL;DR: It is indicated that high concentrations of M-CSF can suppress the cell viability of stromal cells in the decidualization process, and inhibit decidUALization of endometrial stroma cells.

The growth of mouse bone marrow cells in vitro
TR Bradley,Donald Metcalf +1 more
TL;DR: A simple in vitro technique for the growth of colonies from single cell suspensions of mouse bone marrow involves the plating of marrow cells in agar on feeder layers of other cells, those from 8-day-old mouse kidney and 17th day mouse embryo being shown to be the most efficient types of feeder layer.

Stimulation by normal and leukemic mouse sera of colony formation in vitro by mouse bone marrow cells
TL;DR: Using a modification of the agar gel method for bone marrow culture, serum from various strains of mice has been tested for colony stimulating activity and all colonies were initially mainly granulocytic in nature but later became pure populations of mononuclear cells.

TL;DR: Cell colonies developing in agar cultures from mouse bone marrow cells following stimulation either by neonatal kidney cell feeder layers or AKR lymphoid leukemia serum were mixtures of granulocytic and mononuclear cells.
