Osteoclasts and transforming growth factor-beta: estrogen-mediated isoform-specific regulation of production.

abstract：:The recently discovered estrogen receptor-beta (ERbeta) is expressed in rodent and human testes. To obtain insight in the physiological role of ERbeta we have investigated the cell type-specific expression pattern of ERbeta messenger RNA (mRNA) and protein in the testis of rats of various ages by in situ hybridization...
