Abstract : A small number of cells within the mouse thymus were induced to form colonies of mononuclear cells in an in vitro agar system. The specific factor necessary to induce colony formation was present in an extract of placenta, memebranes and uterine tissue from pregnant mice. The relative incidence of the colony forming cells was 104:7.5:1 for mouse marrow, spleen and thymus, respectively. This research is part of a program for the development of therapeutic agents for the enhancement of white cell production after radiation exposure. (Author)
