Scientists Create Human Embryo-Like Structures with Stem Cells
Recently, a team of scientists from UK and USA has made a major breakthrough in the field of In Vitro Fertilization (IVF) and human reproduction.
- These scientists have developed the world’s first artificial human embryo-like structures using stem cells. These embryos appear to be similar to natural embryos from early stages of human development.
- Although these artificial human embryo-like structures lack the development of a beating heart or brain, they do contain cells that can form into a placenta, yolk sac, and embryo.
Importance of new achievement:
- This will help in understanding the effects of genetic disorders and biological causes of recurrent miscarriage.
- Reportedly, neither eggs nor sperm would be needed for the creation of a human embryo.
Stem Cells:
- These are stem cells, which have the unique ability to develop into specialized cell types of the body.
- As the body develops, stem cells continue to provide new cells. Also, they replace specialized cells that have been damaged or destroyed.
Types of Stem Cells:
- Embryonic stem cells: These cells are formed during the blastocyst stage of the embryo. These are pluripotent, but do not contribute to the development of extra-embryonic cells such as the placenta.
- Adult Stem Cells: These cells are found in specific tissues. They repair and build cells of these tissues only.
- Induced pluripotent stem cells (iPS): These are created by fusion of adult stem cells with embryonic stem cells. They help in medical treatment.
