Methods The skeletal muscle stem cells were enzymatically isolated with collagen and dispase, and then purified by different adhesion time from 6 female SD rats. The purified cells were transinfected with adenovirus carrying lac-Z gene, and injected into the bladder neck of 6 autologous and 4 allogeneic rats. Tissues of blader neck and ureter were obtained in sacrified rats after 5 and 15 days, histological examination and X-gal staining were performed.

采用混合酶消化及反复差速贴壁法分离、纯化培养SD大鼠骨骼肌干细胞，然后用携带lac-Z基因的腺病毒载体转染肌干细胞，待转染成功后将携带lac-Z基因的骨骼肌干细胞注射于自体和同种异体的膀胱颈及后尿道周围，分别于注射后5、15d，处死大鼠取出膀胱颈及后尿道，行组织学检查及X-gal染色。

BACKGROUND: Embryonic stem cells develop from early blastular inner cell mass. Under proper condition, ESCs can maintain undifferentiated state in vitro, normal diploid nuclear type, and proliferative potential. In addition, ESCs possess multi-directional differentiation capacity and can differentiate into all sorts of cells of three germ layers.
