CD-209L-Fc Chimera
Symansis" DCSIGNR - Fc Chimera/CD209L - Fc Chimerahcx is a glycoprotein containing 5-25% carbohydrate by weight. A drop in the observed MW after treatment with PNGase F indicates that Symansis" DCSIGNR - Fc Chimera/CD209L - Fc Chimerahcx is N-glycosylated. Symansis" CD209L-Fchcx may also be O-glycosylated Densitometry of protein isoforms visualised by 2-DE. Spot trains are normal in human proteins and highlight the presence of multiple isoforms which differ according to their level of post-translational modification. The triangle indicates the theoretical MW and pI of the protein. 1D SDS-PAGE of Symansis" hcx protein before and after treatment with glycosidases to remove oligosaccharides. A drop in the observed MW after treatment indicates the presence of glycosylation. 1. Koppel EA, et al. (2005) Cell Microbiol. 7: 157-65. |

一般细胞没有自我复制能力,而且也不会分化。
全能干细胞具有能发育成各种组织器官的完整个体的潜能的细胞,如胚胎干细胞。多能干细胞没有发育成完整个体的能力,但具有分化出多种细胞组织的能力,主要在器官再生、修复和疾病治疗方面极具应用价值,多能干细胞还在研究当中,过去认为多能干细胞只能从人胚胎中获得,现在已能用体细胞转化为多能干细胞。
单能干细胞只能向一种类型或密切相关的两种类型的细胞分化,如上皮组织基底层的干细胞、肌肉中的成肌细胞。
低黏附培养板,每孔接种5000个细胞,无血清培养,但是第二天去看,感觉细胞都抱在一起死了,求哪位前辈帮忙看看,这是怎么回事
心肌梗死(Myocardialinfarction,MI)特征是心脏供血减少和心肌功能减弱,成人心脏的自我再生能力有限,使得心肌梗死的状况雪上加霜。由于干细胞具有自我更新复制能力和分化潜能,因此干细胞移植是使心脏组织再生和增强心脏功能的新的方法。最近的研究表明脂肪组织来源干细胞(ADSCs),即从脂肪组织分离的多能干细胞,具有广泛的分化潜能,可分化为心肌细胞。现分享一篇DNA转染(Entranster-H4000)与脂肪来源干细胞和心肌梗死研究的文献,以供参考。
