Human vascular cells are capable of stimudium obtained from cord veins was found lating granulopoiesis in agar culture of to be highly active in comparison to that human bone marrow cells. This effect was obtained from peripheral leukocytes. Enobtained by including vein fragments in dothelial cells within the bone marrow the culture or by using endothelial cells cavity are suggested as a local ...

In long-term marrow cultures, proliferation and differentiation of hemopoietic stem cells occurs for several months. Normally, only the most primitive erythroid progenitor cells are produced (the BFU-E). Following treatment with anemic mouse serum (AMS) or normal mouse serum plus erythropoietin, the BFU-E mature into CFU-E, which then go to produce mature nonnucleated red cells. This developmen...

Human vascular cells are capable of stimulating granulopoiesis in agar culture of human bone marrow cells. This effect was obtained by including vein fragments in the culture or by using endothelial cells separated from the vein of human umbilical cords as feeder cells. Furthermore, the stimulatory capacity of conditioned medium obtained from cord veins was found to be highly active in comparis...
