研究領域與專長

本實驗室的研究目標在探討成體幹細胞維持幹性(stemness)及進行分化(differentiation)的分子機制。人類胎盤為絨毛組織(villi)所構成,組織中的滋養幹細胞(trophoblast stem cells, TS cells)可分化為多核的合體滋養細胞(multinucleate syncytiotrophoblasts, STBs)及移行的外絨毛滋養細胞(migratory extravillous trophoblasts, EVTs)。另外,絨毛組織中的細胞滋養細胞(cytotrophoblasts, CTBs)具有類似TS細胞的特性。GCM1轉錄因子主宰STB 及EVT的分化,其活性受到不同訊息傳遞路徑的正、反向控制。藉由調整這些路徑,我們成功地將CTBs轉分化為TS細胞。胎盤負責母親與胎兒之間養分及氣體的交換。功能不健全的胎盤導致子癇前兆(preeclampsia, PE)及子宮內生長遲緩(intrauterine growth retardation, IUGR)等症狀,使胎兒在懷孕過程中處於營養不良的狀況,將來在成人階段也會有冠狀動脈、高血壓、中風及第二型糖尿病的高好發機率。我們當前利用TS細胞研究(1)維持其幹性的上游調控因子,(2)進一步誘導其為多能性的幹細胞以提供自體細胞療法及(3)研究TS細胞分化缺陷與PE及IUGR成因的關連性。
