美国科学家在实验室培育可移植肝脏过程中,取得一项重大突破。他们利用装有细胞的3D打印机打印出迷你肝脏,深0.5毫米,宽4毫米,拥有很多与真实肝脏一样的功能,包括产生负责将激素、盐和药物运送到身体各处的蛋白质。打印3D迷你肝脏这一成就是由加利福尼亚州的生物打印领域先驱Organovo公司取得。打印过程中,3D打印机逐层打印肝脏细胞和血管内壁细胞,一共打印了大约20层。血管内壁细胞负 American scientists made a major breakthrough in the development of a portable liver in the laboratory. They use a cell-packed 3D printer to print mini-livers, 0.5 mm deep and 4 mm wide, that have many of the same functions as a real liver, including the production of proteins responsible for the delivery of hormones, salts and drugs throughout the body. Print 3D Mini Liver This achievement was made by Organovo, a pioneer in bio-printing in California. During printing, the 3D printer prints liver cells and blood vessel linings layer by layer, printing a total of about 20 layers. Vascular wall cells negative
