Abstract
A modified culture system was developed to grow and quantitate megakaryocyte colonies from mouse bone marrow more efficiently than previously described. Using this method, 30% of CFU-M [colony-forming unit, megakaryocyte] in normal marrow cells and 70 to 90% of CFU-M in regenerating marrow cells were killed by high specific activity 3H-TdR [thymidine] in vitro. CFU-M are apparently proliferating even in normal adult hemopoietic tissue, but the proportion of cells that are proliferating is greater in regenerating marrow than in normal intact mice.
