美国科学家6月13日说,他们新近开发出的一种技术,有望帮助刺激人类胚胎干细胞更高效地分化成其他类型的细胞。 胚胎干细胞是人体中保留的未成熟细胞,具有再分化形成其他细胞和组织器官的潜力。利用胚胎干细胞培育供移植用的细胞、组织或器官,据认为在医疗上具有重要价值。但是刺激干细胞在体外进行 American scientists said June 13 that a technology they have recently developed is expected to help stimulate more efficient differentiation of human embryonic stem cells into other types of cells. Embryonic stem cells are immature cells that remain in the human body and have the potential to redistribute and form other cells and tissues and organs. The use of embryonic stem cells to culture cells, tissues or organs for transplantation is considered medically important. But stimulating stem cells is done in vitro
