A rapid and reliable method of definitively identifying mutant (Sl/Sld) and wild type (+/+) mouse embryos in segregating litters is described, based on the mean cell volume determination of circulating foetal erythrocytes by an electronic particle counter. The mean cell volumes of yolk sac derived nucleated erythrocytes from +/+ and Sl/Sld embryos are(More)
Adult SI/SI-d mutant mice have severe macrocytic, normochromic anemia. Moreover these animals are unresponsive to the stimulation of erythropoietin in vivo. By means of a bone marrow cell suspension culture system, the present investigation shows that in adult SI/SI-d marrow, there are cells capable of responding in vitro to erythropoietin in a normal(More)
