Alkylation-induced apoptosis of embryonic stem cells in which the gene for DNA-repair, methyltransferase, had been disrupted by gene targeting

Gene targeting in embryonic stem cells.

One day, you will discover a new adventure and knowledge by spending more money. But when? Do you think that you need to obtain those all requirements when having much money? Why don't you try to get something simple at first? That's something that will lead you to know more about the world, adventure, some places, history, entertainment, and more? It is your own time to continue reading habit....

Gene targeting of a disease-related gene in human induced pluripotent stem and embryonic stem cells.

We report here homologous recombination (HR)-mediated gene targeting of two different genes in human iPS cells (hiPSCs) and human ES cells (hESCs). HR-mediated correction of a chromosomally integrated mutant GFP reporter gene reaches efficiencies of 0.14%-0.24% in both cell types transfected by donor DNA with plasmids expressing zinc finger nucleases (ZFNs). Engineered ZFNs that induce a sequen...

transfection of human hematopoietic stem cells by a gene targeting construct containing the β-globin gene

background: replacment of cd133+ cell’s β globin gene by using a gene targeting construct containing the β globin gene and essential elements for homologous recombination. materials and methods: pfbggt was amplified, then digested using the nhei and xhoi restriction enzymes, and finally, a 13.3 kb band (naked dna) was extracted from the agarose gel. biological activity of positive and negative ...
