干细胞具有再生各种生物组织器官的潜能,在医学界被称为“万用细胞”。近几年来,干细胞领域重要的进展是培养人体的类器官,目前已经培养出人类大脑、心脏等多种器官。胚胎干细胞由于能被诱导分化为机体几乎所有的细胞类型而在治疗疾病方面有着极其诱人的前景。但是,之前科学家却一直未能在实验室中使胚胎干细胞独自发育成具有复杂的三维结构的组织。近期,这一领
Stem cells have the potential to regenerate a variety of biological tissues and organs and are known in the medical community as “universal cells.” In recent years, important progress in the field of stem cells has been to cultivate human organs and organs. At present, various organs such as the human brain and heart have been cultivated. Embryonic stem cells have an extremely attractive prospect for treating diseases because they can be induced to differentiate into almost all types of cells in the body. However, scientists have been unable to develop embryonic stem cells into tissues with complex three-dimensional structures in the laboratory until now. Recently, this leader
