【摘要】：干細(xì)胞(stem cells, SCs)是指那些處于分化過程之中，具有分裂增殖能力，在一定條件下，能分化產(chǎn)生一種以上功能細(xì)胞的原始細(xì)胞。肝干細(xì)胞(hepatic stem cells, HSCs)是指具有干細(xì)胞特點(diǎn)，并能增殖、分化成為肝細(xì)胞和膽管細(xì)胞，參與肝臟結(jié)構(gòu)和功能重建的一類細(xì)胞。 根據(jù)肝干細(xì)胞的特性，其臨床應(yīng)用主要包括產(chǎn)生移植所需肝臟組織或器官及用于干細(xì)胞治療。目前分離和篩選得到“種子”肝干細(xì)胞的方法主要是熒光激活細(xì)胞篩選法。肝干細(xì)胞可分為肝源性和非肝源性。肝源性肝干細(xì)胞包括肝細(xì)胞、卵圓細(xì)胞和小肝細(xì)胞等，非肝源性肝干細(xì)胞主要包括胚胎干細(xì)胞、骨髓干細(xì)胞等。目前關(guān)于肝干細(xì)胞的相關(guān)研究取得了部分成果，但大多數(shù)研究還僅限于動物實(shí)驗(yàn)研究，臨床應(yīng)用還較少，肝干細(xì)胞在肝移植方面的應(yīng)用研究尚處于空白，而用于細(xì)胞治療的具體作用機(jī)制還不清楚，肝干細(xì)胞體外提取、純化、培養(yǎng)等技術(shù)還不夠成熟，采用何種移植方式還沒有科學(xué)定論，，用于治療的長期有效性和安全性還缺乏相關(guān)資料，卵圓細(xì)胞與肝癌和肝硬化的發(fā)生可能有密切關(guān)系，胚胎干細(xì)胞的研究與應(yīng)用還面臨的倫理學(xué)挑戰(zhàn)，胚胎干細(xì)胞的致畸胎瘤等問題也有待解決。但肝干細(xì)胞在肝臟損傷、肝炎、肝硬化、肝癌等肝臟疾病的治療及肝移植術(shù)后抗排異等方面的相關(guān)進(jìn)展表明，肝干細(xì)胞在肝臟疾病臨床應(yīng)用中具有十分廣闊的前景。本綜述介紹了肝干細(xì)胞的分離、篩選、分類與特性、體外擴(kuò)增與分化、在肝臟疾病中應(yīng)用的研究進(jìn)展及面臨的問題，并展望其發(fā)展前景。
[Abstract]:Stem cells (SCS) are those in the process of differentiation, with the ability to divide and proliferate, under certain conditions. Hepatic stem cells (HSCs) are characterized by stem cells and can proliferate. Differentiation into hepatocytes and bile duct cells involved in the reconstruction of liver structure and function. According to the characteristics of liver stem cells. Its clinical applications mainly include producing liver tissues or organs needed for transplantation and for use in stem cell therapy. At present, "seeds" are obtained by isolation and screening. The main methods of hepatic stem cells are fluorescence activated cell screening. Liver stem cells can be divided into hepatogenic and non-hepatogenic. Hepatogenic liver stem cells include hepatocytes. Oval cells and small liver cells, non-hepatic stem cells mainly include embryonic stem cells, bone marrow stem cells and so on. However, most of the research is limited to animal experiments, the clinical application is relatively small, the application of liver stem cells in liver transplantation is still blank, but the specific mechanism of cell therapy is not clear. The extraction, purification and culture of liver stem cells in vitro are not mature enough. There is no scientific conclusion about the transplantation method, and the long-term efficacy and safety of the treatment are still lack of relevant information. Oval cells may be closely related to the occurrence of liver cancer and cirrhosis. The research and application of embryonic stem cells still face ethical challenges. However, the progress of liver stem cells in liver injury, hepatitis, liver cirrhosis, liver cancer and anti-rejection after liver transplantation, etc. Liver stem cells have a broad prospect in clinical application of liver diseases. This review introduces the isolation, screening, classification and characteristics of liver stem cells, expansion and differentiation in vitro. Research progress and problems in the application of liver diseases, and prospects for its development.
