Detailed explanation-1: -Importance of stem cells in medical research Stem cells are considered to be of great importance in medical research due to their unique ability to differentiate into various types of cells and tissues, as well as their potential for self-renewal.
Detailed explanation-2: -Stem cells provide new cells for the body as it grows, and replace specialised cells that are damaged or lost. They have two unique properties that enable them to do this: They can divide over and over again to produce new cells. As they divide, they can change into the other types of cell that make up the body.
Detailed explanation-3: -Induced pluripotent stem cells (iPS) Scientists create these in a lab, using skin cells and other tissue-specific cells. These cells behave in a similar way to embryonic stem cells, so they could be useful for developing a range of therapies.
Detailed explanation-4: -The embryonic stem cells used in research today come from unused embryos. These result from an in vitro fertilization procedure. They are donated to science. These embryonic stem cells are pluripotent.
