研究方向研究室特色

我們實驗室主要研究細胞分化的過程。在發育過程中,胚胎細胞藉由分化過程來形成各式功能的細胞。分化作用也會在成體中發生,並對成體組織代謝及恆定極為重要。因此,研究細胞分化不只有助於了解及治療因細胞功能不足而產生的先天性疾病,且直接有助於未來在醫學上產生新生細胞來修補受損組織。

我們主要用果蠅這個模式生物來研究在活體中,基因如何調控細胞分化。實驗室中有兩個主要方向:(1)探討神經母細胞的形成過程中,原神經蛋白如何活化下游基因來促進母細胞分化。我們目前著重於探討核內肌動蛋白和原神經蛋白之間的關係。(2)成體幹細胞 (adult stem cell) 自我新生的調控在 維持組織恆定中扮演 重要功能 。自我新生能力太強時, 細胞分化會被抑制。 反之, 過早進入細胞分化會降低幹細胞的自我新生。我們實驗室最近的研究在探討成體中的配子幹細胞如何受到BMP 或其它訊息傳導路徑的影響來維持在自我新生及細胞分化中的協調。
