郭紘志老師實驗室

  • 全能性幹細胞有兩種,一種是由發育中的胚胎所建立而成的胚胎幹細胞,另外一種是由體細胞再編程而建立的誘導性多能幹細胞。全能性幹細胞具有在體外或體內分化成各種細胞的能力,藉此所得分化的細胞可提供做為更新修復受傷或帶有病徵細胞的來源,亦可作為藥物篩選的平台。探討全能性幹細胞內調控自我更新與分化之間的平衡機制對於其應用是相當重要的。然而,雖然全能性幹細胞內的轉錄調控機制日益被了解,轉錄後機制如何去影響細胞的全能性維持與早期譜系分化仍相當未知。轉錄後修飾常常與非編碼RNA相關,而我們最近的研究發現反式剪接RNA在調控全能性幹細胞的全能性有嶄新的機制。為了探討非編碼RNA在細胞與分子的功能,我們整合全系統偵測方式、全能性幹細胞平台與體外分化的實驗。藉此綜合的方法,我們將能探索轉錄後修飾如何調控細胞分化命運以及變異的RNA如何導致人類疾病之謎。

    我們實驗室的另外一個研究主軸是探討轉錄因子如何調控全能性幹細胞形成神經外胚層如大腦與脊隨的網絡機制。我們已經成功建立許多體外神經分化的平台,利用這些平台,我們得以探討重要的轉錄因子,如LHX2與SOX2在全能性幹細胞往神經方向分化所扮演的角色。除此之外,我們也利用全能性幹細胞體外形成的立體大腦結構來探討調控早期大腦皮層分化的分子機轉。另外,我們也利用帶有疾病的人類誘導型全能性幹細胞及其分化的神經前驅細胞作為體外研究平台,以期找到新的臨床治療方式。

    我們實驗室的研究主要著重於:

    • 環狀RNA與反式剪接RNA在維持全能性、再編程與調控分化的功能
    • 人類全能性細胞進行大腦皮層分化的分子機轉
    • 利用人類誘導型全能性幹細胞以其分化的神經前驅細胞做為平台探討神經退化性疾病
