What are facts about embryonic stem cell research?

All embryonic stem cells are undifferentiated cells that are unlike any specific adult cell.

Human embryonic stem cells are derived from in vitro fertilized embryos less than a week old

Embryonic stem cells are of great interest to medicine and science because of their ability to develop into virtually any other cell made by the human body.

Scientists have been attempting to isolate and culture human embryonic stem cells for more than a decade.

Human embryonic stem cells will offer insights into developmental events that cannot be studied directly in humans in utero or fully understood through the use of animal models

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
