| 英文摘要 | The fate of human hematopoietic stem cells (hscs)/progenitor cells (hpcs) is influenced by bone marrow (bm) stromal cells. to investigate the role of stromal cells in the hematopoietic support, we have transduced human fetal bm stromal cells (fbmscs) with a human telomerase catalytic subunit (htert). one of the resultant cell lines was identified as osteoblasts, because it contained mineral deposits and constitutively expressed osteogenic genes osteocalcin, osteopontin, collagen type i, osteoblast marker alkaline phosphatase, but not marrow stromal cell marker stro-1 and cd105. the htert-transduced fetal bm-derived osteoblastic cells (fbmob-htert) can actively maintain the capacity of self-renewal and multipotency of hscs/hpcs at least partly through transcriptional up-regulation of hematopoietic growth factors such as stem cell growth factors (scfs) and wnt-5a during interaction with hscs/hpcs. the enhanced transcription of scfs and wnt-5a appears to be mediated by cd29 signaling. moreover, the fbmob-htert cells seem superior to primary fbmscs in supporting hematopoiesis, because they are more potent than primary fbmscs in supporting the ex vivo expansion and long-term culture initiating cells activity of hscs. the fbmob-htert cell line has been maintained in vitro more than 125 population doublings without tumorigenicity. the results indicate that the fbmob-htert is useful for the study of molecular mechanisms by which osteoblasts support hematopoiesis. |
