Study Notes

Embryonic Stem Cells

Embryonic stem cells are cells derived from embryos, which have the ability to differentiate into all cell types in the body.

Obtaining Embryonic Stem Cells

Embryonic stem cells can be obtained from excess embryos created during in vitro fertilization (IVF) procedures.
They can also be obtained through somatic cell nuclear transfer (SCNT), a process where the nucleus of an adult cell is transferred into an egg cell.

Purpose of In Vitro Fertilization

The purpose of in vitro fertilization (IVF) in obtaining embryonic stem cells is to generate excess embryos that are not used for reproductive purposes.

Somatic Cell Nuclear Transfer

Somatic cell nuclear transfer (SCNT) is commonly used for cloning animals and potentially for therapeutic purposes.

First Mammal Developed using SCNT

The first mammal developed using somatic cell nuclear transfer (SCNT) is Dolly the sheep, cloned in 1996.
