Seeking a Simpler life
To create mice with manipulated chromosomes, Bradley's group alters the DNA of stem cells stem cells, unspecialized human or animal cells that can produce mature specialized body cells and at the same time replicate themselves. Embryonic stem cells are derived from a blastocyst (the blastula typical of placental mammals; see embryo gucci replica), which is very young and injects these chanel replica immature cells into early-stage embryos. If the altered stem cells develop into the mouse's reproductive hermes outlet cells, all cells in the embryo's offspring will have the modified chromosomes.
