Where the stem cells come from?

Embryonic stem cells. These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.Mar 23, 2013 read more

First and foremost, it should be noted that not all stem cells come from embryos. As a matter of fact, despite the amount of public attention they get, embryonic stem cells are among the smallest group of stem cells currently being researched. read more

Placenta derived stem cells - Up to ten times as many stem cells can be harvested from a placenta as from cord blood. Adult stem cells - Many adult tissues contain stem cells that can be isolated. The goals of stem cell research include curing diseases, cloning, and gene-line engineering. read more

When a stem cell divides, each "daughter" cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. read more
