Bookmark or Share- Embryonic Stem Cell - Definition and Uses - Biology DictionaryEmbryonic stem cells are totipotent, meaning they can divide into any other cell type within an animal. This is a process known as cellular differentiation. After the sperm reaches an egg (oocyte), fertilization occurs and the DNA from the two cells merge into a single nucleus, in a single cell.
- Stem Cell Basics | STEM Cell Information - National Institutes of HealthResearchers study many different types of stem cells. There are several main categories: the “pluripotent” stem cells (embryonic stem cells and induced pluripotent stem cells) and nonembryonic or somatic stem cells (commonly called “adult” stem cells).
- Stem cells: What they are and what they do - Mayo ClinicEmbryonic stem cells are the most versatile since they can develop into all the cells of the developing fetus. The majority of stem cells in the body have fewer abilities to give rise to cells and may only help maintain and repair the tissues and organs in which they reside.
- Embryonic Stem Cells - The Definitive Guide - Biology DictionaryEmbryonic stem cells (ESCs) are stem cells derived from a 3 – 5 day old human embryo (AKA a blastocyst). ESCs are pluripotent, meaning they have the potential to become any of the other 200+ types of cells found in the human body.
- Embryonic Stem Cells - Stem Cells and the Future of Regenerative ...Embryonic stem cells (ESCs) are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4th to 7th day after fertilization. In normal embryonic development, they disappear after the 7th day, and begin to form the three embryonic tissue layers.
