Estrogen promotes early osteoblast differentiation and inhibits adipocyte differentiation in mouse bone marrow stromal cell lines that express estrogen receptor (ER) alpha or beta.

abstract：:Leydig cells from mature rat testes contain high levels of 11 beta-hydroxysteroid dehydrogenase (11HSD), an enzyme that oxidatively inactivates glucocorticoids. We have proposed that the 11HSD of Leydig cells protects the testis from the effects of high levels of glucocorticoids, as may occur in stress and Cushing's d...
