Document Summary
When you search for embryonic stem cell case (spinal cord injury), you find a whole lot of business journals- huge interest among investment community. Subsequent trials will tell whether it can really work. Promises of animal biotechnology and stem cells: conserve environment- get animals to live on small acreage, advance human health- we use a lot of animal models. Frozen bull semen and embryos: embryo transfer- early 1980s. * in vivo- in living organism: embryo splitting and cloning- early 1990s. Embryo formed- can split into two bunches of cells or more. This is how you get fraternal twins: genetic preservation. This is when you freeze tissue and germ cells from highly-prized animal: somatic cell nuclear transfer. Transferring genes among species- make lots of copies. Dan gardner- columnist for ottawa citizen- predictions usually wrong: mcgrath in 1987 was wrong. Ian wilmut- runs institute in scotland where they cloned sheep: possibility of cloning humans- evil.
