Follow-up studies of cortisone teratogenicity in CD1 strain mice
H. T. Loevy
The present study was done to evaluate the incidence of cortisone-induced
cleft palate in the offspring of CD1 strain mice whose mothers had been
injected with cortisone during their own pregnancy. The incidence of
induced cleft palate was as high as the incidence of cortisone-induced
cleft palate reported previously for the CD1 strain, indicating that the
predisposition of CD1 mice to the teratogenic effects of cortisone is not
altered significantly when the F2 generation is treated in utero with the
same teratogenic agent.
