主要方法:
- 40只多胞胎圣伊内斯羊被分为治疗 (rbST) 和控制 (盐水) 组.
- 使用FSH诱导超排卵,在协议前3天服用rbST.
- 卵巢反应,IGF-1水平和胚胎基因表达 (BCL2,PRDX1,SIRT2,CDH1) 进行了分析.
主要成果:
- rbST显著增加了血清IGF-1水平.
- 在胚胎中,rbST降低了BCL2和PRDX1的表达,同时提高了SIRT2和CDH1的表达.

01:08Cloning of Dolly the Sheep
7.2K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

01:24Methods of Nuclear Reprogramming
2.1K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...
