these results suggest that the arcuate nucleus in the hypothalamus stimulates the differentiation of gh and prl cells during postnatal life , and that the ovary stimulates the differentiation of prl cells through a direct effect on the anterior pituitary lobe but inhibits that of gh cells via the arcuate nucleus in the hypothalamus , while the differentiation of nongranulated cells is little affected .
