Question

Why do scientists want to use stem cell lines?

Answer 1

Once a stem cell line is established from a cell in the body, it is essentially immortal, no matter how it was derived. Once established, a cell line can be grown in the laboratory indefinitely. Stem cell lines grown in the lab provide scientists with the opportunity to engineer them for use in transplantation or treatment of diseases. In the future, scientists are able to modify human stem cell lines by using gene therapy or other techniques to overcome this immune rejection.
