補益類中藥及其方劑對於人體幹細胞之系統分析研究

在臨床上,傳統中藥對人體疾病已有廣泛應用,而在許多重大疾病的西醫治療上,中藥亦具有輔助效果,例如目前已知,中藥對於輔助癌症化療後的生理系統恢復,效果明顯。然而到目前為止,對於中藥在細胞組織生理的影響,了解仍非常有限。而近年來,幹細胞的研究已顯示成體幹細胞具多組織修復再生功能,小自身體日常組織細胞之更新,大至提供個體受傷之組織再生功能細胞,都由幹細胞主導。在人體生理恢復過程中,幹細胞調節顯得格外重要,特別是在組織細胞面對環境壓力時,其幹細胞更是扮演著重要角色。

本計畫旨在以系統分子醫學的角度,應用藥物基因體醫學之分析,探討補益類中藥在癌醫療過程中,對人體組織幹原細胞受損之保護及修復藥理,並藉而建立補益類中藥對人體組織幹原細胞基因體表達影響之資訊。

在過去的研究中,本實驗室已建立人體組織幹細胞分離鑑定及培養之平台──從骨髓、脂肪、臍帶血、包皮、頭皮、羊膜等組織來源分離取得幹細胞,有效率地提供各組織幹細胞之生長、分化及分析檢測,並已針對黃耆、西洋參、三七、柴胡、紅景天等活血化瘀藥材對於保護造血功能及促進間質幹細胞生長及分化作探討。本計劃擬進一步針對一些補益類中藥材──包括補中益氣湯、四物湯及生脈散等補血養氣、增進細胞生理機能之複方藥材──對於多種幹細胞生理調節之影響進行研究。利用特定基因表達及蛋白圖譜表達之差異比較,將補益類複方藥材反應於造血及間質細胞生長及分化潛能影響,利用初代培養(primary culture)的各組織細胞之分化初、中、後期之基因表達的細胞表面標記抗原及功能蛋白,將利用螢光免疫染色(immuno-florecent staining)、西方墨點法(Western blotting)等作定量、定性分析。觀察在中藥作用下,多種幹原組織細胞基因表達之變化、基因調控對於環境刺激因子反應,以及這些環境刺激彼此間的分子相互作用,做出系統分析,藉此建立評估中藥對於細胞生理與功能影響之資訊。

本計畫如能順利執行,將對中藥在個體幹細胞生理調節上有更完整了解,提供中藥醫療作用於人體組織幹細胞之分子生理系統效用評估範例,建立一現代化中藥藥理鑑定的新方向,以助中藥之國際化發展。

A Systematic Biological Evaluation of Some Bu-Yi Chinese Herbs? Pharmacogenomic Effect on Human Tissue Stem/Progenitor Cells

Daniel Tzu-bi Shih

In clinic, Chinese traditional drugs have been widely prescribed for human diseases, and shown helpful in treatment of many major illnesses. For an example, Chinese drugs have been found significant effect on the recovery rate of chemotherapeutically treated cancer patients’ health. To date, however, the physical-pharmacological understanding of their effects is very limited. Recent studies on stem cells have shown that many adult tissue stem cells are not only capable of maintaining and renewing the catabolized tissue cells in organs but also responsible for our body tissue injury repairs. Most stem cells are normally situated in quiescent state and activated only when stressed by their normal environmental changes. Our body tissue stem cells are therefore very important in protection and maintenance of tissue health, particularly when they were stressed and damaged by physical and chemical environmental pressures. 
The objective of this proposal study is to investigate the molecu
