Abstract

The current study was undertaken to determine the effects of sex steroid hormones(estrogen, testosterone and 19-nortestosterone) on differentiation and proliferation of pig preadipocytes. The preadipocytes were isolated from the backfat of new-born female pigs by collagenase digestion. 10－8M and 10－7M sex steroid hormones were treated to the cultured preadipocytes. Sex steroid hormones treated during the early stage of cell growth did not affect differentiation and proliferation of preadipocytes. However, testosterone and 19- nortestosterone treated during the late stage of cell growth stimulated differentiation of pig preadipocytes.

본 연구는 스테로이드 성호르몬 즉 에스트로겐, 테스토스테론 및 노르테스토스테론이 돼지 지방전구세포의 분화와 증식에 미치는 영향을 구명하기 위해서 수행하였다. 지방전구세포는 갓난 암퇘지의 등지방조직을 떼어내어 coll- agenase를 처리해서 분리해서 배양했다. 세포 배양중에 10－8M과 10－7M의 스테로이드 성호르몬을 처리했다. 세포배양 전기에 스테로이드 성호르몬을 처리했을 때 지방전구세포의 분화나 증식에 아무런 영향을 미치지 않았고, 세포배양 후기에 처리했을 때는 테스토스테론과 노르테스토스테론이 세포분화를 촉진시켰다.
