The effect of various concentrations of retinoic acid on the growth of committed granulomonopoietic precursors (CFU-GM) was studied on semisolid agar cultures. Retinoic acid increased the growth of day 14 CFU-GM but had no significant effect on day 7 CFU-GM. Since the latter are believed to represent the progeny of day 14 CFU-GM it is suggested that the effect of retinoic acid is confined to the early stages of granulomonocytic differentiation.
Retinoic acid enhances the growth of only one subpopulation of granulomonocyte precursors.

Abstract
The effect of various concentrations of retinoic acid on the growth of committed granulomonopoietic precursors (CFU-GM) was studied on semisolid agar cultures. Retinoic acid increased the growth of day 14 CFU-GM but had no significant effect on day 7 CFU-GM. Since the latter are believed to represent the progeny of day 14 CFU-GM it is suggested that the effect of retinoic acid is confined to the early stages of granulomonocytic differentiation.
