Hemopoietic colony formation in agar occurred spontaneously in mass cultures of marrow cells obtained from a number of species (guinea pig, rat, lamb, rabbit, pig, calf, human and Rhesus monkey). This contrastcd with the observation that colony formation by mouse bone marrow exhibited an absolute re

Mouse bone marrow cells in suspension were separated into a number of fractions on the basis of cell density by equilibrium density gradient centrifugation, or on the basis of cell size by velocity sedimentation. After each type of separation, the cells from the various fractions were assayed for th
## Abstract Granulocyteβmacrophage colony formation from bone marrow cells in soft agar is dependent upon the presence of a stimulating factor and the number of colonies is related to its concentration. This doseβresponse effect provided a measurement of the responsiveness to stimulation of colony
