Research Interests

Plasticity means the ability of somatic cells to convert or to adapt to the new phenotype, which has been demonstrated in all examples of cell reprogramming including transdifferentiation, nuclear transplantation, cell fusion, neoplatic transformation and interconversions between somatic stem cells. To investigate the molecular basis of somatic cell conversion is clinically significant for two reasons: (1) Somatic cell conversion (transdifferentiation) predisposes to certain forms of neoplasia and cancer. (2) Somatic cell conversion is clinically important to the newly emerging science of regenerative medicine. To solve the shortage for organ transplantation, an alternative strategy is to produce isogenic cells to replace sick or damaged tissue from reprogrammed somatic cells. Currently, our group is focusing on development of diabetic therapies in combination with stem cells and somatic cell reprogramming. For example, we found insulin-producing cells can either be generated either from acinar transdifferentiation, dermal fibroblast derived “induced pulripotent stem cells” or liver stem/progenitor cells which can possibly be used for transplation therapies for diabetes. Furthermore, our group also aims to determine the possible mechanism regulating plastic transformation which may lead to development of neoplasia and cancer in pancreas.



  糖尿病是全球性流行之慢性疾病,根據國際衛生組織的資料顯示目前全世界有超過一億五千萬的糖尿病病患,預估二十年後會超過三億五千萬,其中將近五分之一是第一型糖尿或是缺乏胰島素分泌貝它細胞的病患,然因胰島來源缺乏導致無法大量用胰島移植以治療糖尿病患。本實驗室的研究主題之一在探討體細胞可塑性的調節機制,以及是否可將其運用在糖尿病的治療方面,特別是著眼於將病人的體細胞轉變為胰島素分泌貝它細胞,以為糖尿病提供一個可進行自體移植治療方法。例如誘導式多潛能幹細胞可以利用病人的體細胞製造出來,所以也可以避免或降低移植所造成的排斥問題,但是如何使這些”誘導式多潛能幹細胞(induced pluripotent stem cells)”再分化為具有特定功能的細胞,並且是否可以進一步地應用於疾病的移植治療來源,尚未有確切的答案。所以本實驗的目前研究重點是找尋可以使誘導式多潛能幹細胞分化為胰島素分泌貝它細胞的方法,進一步再將這些胰島素分泌貝它細胞糖尿病小鼠的模式,觀察其糖尿病症狀是否減輕,除預期可作為糖尿病細胞療法的先導研究外,並可對誘導式多潛能幹細胞的分化機轉作更深入的探討。

  此外在胰臟癌化的過程中,發現有胰腺細胞轉分化為胰管細胞甚至產生類肝細胞的現象,本實驗室發現經控制微環境的方式或致癌基因的表達,都可以改變胰腺細胞的可塑性,這結果提供了新的方向來進行胰臟癌化的機制研究,我們e更進一步建立誘導式Cre/loxP 特定點重組追蹤系統的基因轉殖小鼠來進行研究,以找尋這些造成胰臟早期癌化的前驅細胞源頭及轉化機制。
