Erythroid progenitors lacking SOCS-1 are hypersensitive to Epo. Fetal liver cells isolated from SOCS-1+/+ (open circle), +/− (triangle) and −/− (closed circle) mice were plated in methylcellulose with varying concentrations of Epo. CFU-E numbers were determined 2 days later. The results shown are expressed as the percentage of the maximal colony numbers for the 1 U/ml Epo plates (+/− standard error; n = 6). Astericks indicate statistically significant (Student’s t-test) differences between −/−and +/− or +/+ cells with P-values displayed
