What are Stem cell? Stem Cells are remarkable cells that can form into much other type of cells, which is in the body. A stem cell is like a repairing system that is within the body. The stem cell can be divide unlimited replenish to other cells so it can have the potential to either remain a stem cell or become another type of cell with a more specialized function within the body system (muscle cell, red blood cell, or brain cell).Stem cell can have the ability to renew themselves through mitosis and it can turn into many different specialized cells. Embyronic stem cells are derived from blastocysts, adult stem cells are found in adult tissues, cord blood stem cell can be found in a harvested from an umbilical cord (following birth). Stem cells are cells that have yet to become designated for a particular function inside the body. They are capable of morphing into all kinds of human tissue and some people believe they may hold the cure to some devastating diseases. Stem cells can be obtained in several ways, but when an embryo is used, it is either the product of cloning or in-lab fertilization. In its first few days, the embryo divides and grows into a ball of uniform, unspecialized cells. Once approximately six days have passed, the cell cluster has developed into a blastocyst. The blastocyst consists of a spherical layer of cells surrounding a cavity filled with fluid and stem cells. The stem cells are harvested, destroying the blastocyst.
The harvested stem cells multiply into more unspecialized cells in the lab. The hope held by research supporters is that these cells may be directly transplanted into diseased human tissue in the body or be morphed into specialized tissue and then transplanted.

 “A medical procedure whereby Human Fetal Stem Cells are transplanted into a patient” "These cellular building blocks are usually administered intravenously and subcutaneously (under the skin). It is a painless procedure, which takes place in approximately one hour, and has no negative side effects.” |
