What are iPS Cells?
What is SCNT?
A process that occurs during development by which cells take on their specialized functions, such as the ability of a red blood cell to carry oxygen or a nerve cell to send an electrical signal.
An early stage embryo, about 5 days old. A blastocyst is a microscopic clump of about 150 cells. It is produced from an egg that has been fertilized in vitro but has not yet been implanted in the uterus. The blastocyst is about the same size as the cross section of a human hair.
The ability of a stem cell to produce more stem cells with identical characteristics as the "parent" cell.
The activation of an unfertilized egg by chemical means. These chemical signals cause the egg to begin to divide much as it would after normal fertilization. Scientists believe that these dividing cells could also be used to derive embryonic stem cells. However, these embryonic stem cells would carry the genes from only the woman from whom the unfertilized eggs were retrieved.
Pluripotent stem cells
Can make all 210 cell types in the body
Cord blood stem cells
Can make about 15 cell types in the body
Adult stem cells
Can make only the same type of cells
