the mitotic rate ( percentage s-phase cells ) estimated by tritiated thymidine suicide rose from 45.2 % to 68.4 % ( p less than 0.05 ) in the case of cfu-e and from 16.4 % to 45.1 % ( p less than 0.05 ) for bfu-e following treatment with rhuepo thus indicating in-vivo sensitivity of both the primitive as well as the mature erythroid progenitors to the hormone .
