干细胞是一类具有无限分化能力和修复器官功能的原始细胞，是一种重要的细胞资源，具有巨大的研究价值和临床应用前景。干细胞及其衍生组织、器官可应用于临床，形成一种全新的治疗手段或"药物"，干细胞治疗将在未来5到10年对传统医疗行业产生颠覆性突破，也将促进现代制药业巨大转型，同时产生巨大的新兴市场。如何正确理解国家政策合法开展干细胞临床研究推进干细胞产业发展是值得关注的重要课题。本文浅析了干细胞的概念以及发展现状，阐述了近几年医院在探索干细胞领域的实践以及成效，并展望了干细胞的未来发展前景。

Stem cell, an initial cell with unlimited proliferation potential and the ability to repair the damaged tissues and organs, is an important cell source with broad research values and potential clinical applications. Stem cell, its derived tissues and organs can be developed to a new therapeutic method or drug in the clinic. In the next 5 to 10 years, stem cell therapy will make a significant breakthrough upon the traditional medicine system. It will also promote the transformation of the modern pharmaceutical industry and create a huge emerging market. How to correctly understand the national policy for undertaking the stem cell clinical research and promoting the stem cell industry development must be concerned as the important topic. This article briefly introduce the stem cell concept and the current development situation, expounds the practice and effectiveness of Shanghai East Hospital in stem cell research in the recent years, and forecasts the future research of stem cell in there.
