β¦ Synopsis
From a stock culture of Cylindrotheca sp., non-motile colony-forming cells were observed and isolated. Colony-forming cells produced both single cells and colony-forming cells in liquid media, the rate of single cell production varied among clones. The single cells derived from colony-forming cells were also isolated, which were able to produce both colony-forming cells and single cells in liquid media. The cells derived from colony-forming cells never moved on the agar surface.

Lethally irradiated LAFl mice were protected by various numbers of isogenic bone marrow cells. At intervals, cells from femoral bone marrow and spleen were assayed for their content of colony forming units (CFU) by retransplantation into other lethally irradiated mice and counting of spleen nodules
