Abstract
The effects of chloramphenicol (CAP) and thiamphenicol (TAP) on mouse and human in vitro erythroid (CFU‐E) and granulocytic (CFU‐C) colony forming units have been studied. Both drugs inhibited CFU‐E growth in a concentration‐dependent, stereospecific, manner. Complete inhibition of human CFU‐E growth was observed at a CAP concentration of 10 μg/ml while a concentration over 50 μ/ml was required to inhibit CFU‐C growth. Furthermore, whereas the inhibition of CFU‐C growth could be blocked in vitro by high colony stimulating factor concentrations, inhibition of CFU‐E growth was not affected by increased erythropoietin (ESF) levels. The lack of protection by ESF may account for the apparent vulnerability of erythroid cells to CAP in vivo.
