Proportion of hormone cell populations in female wild-type and delta-like 1 homologue (Dlk1)-null mutant mice. Pituitaries from 6-week-old female Dlk1-null and wild-type mice were dispersed and the number of cells positive for each pituitary hormone quantified after immunofluorescent staining. Data are shown as the mean ± SEM of three to six mice. ACTH, adrenocorticotrophic hormone; FSH, follicle-stimulating hormone; LH, lutesinsing hormone; PRL, prolactin; TSH, thyroid-stimulating hormone.
