|
Growth factor
|
An external regulatory protein that stimulates the growth and division of cells
|
|
|
Apoptosis
|
a process in which a cell is programmed to die
|
|
|
Cancer
|
a disorder in which some of the body's own cells lose the ability to control growth
|
|
|
Embryo
|
an organism in its early stage of development
|
|
|
Differentiation
|
a process in which cells become specialized in structure and function
|
|
|
Totipotent
|
having the ability to develop into all the tissues of the body.A fertilized egg divides over and over to form new cells. The fertilized egg and the cells produced by the first few divisions are totipotent
|
|
|
Pluripotent
|
able to develop into all the body's cell types, but not capable of developing into the tissues surrounding the embryo. EArly in development, a human embryo forms into a blastocyst. a blastocyst is a hollow ball of cells with a group of cells inside called the inner cell mass. The inner cell mass becomes the embryo itself.The cells of the inner cell mass are pluripotent and can develop into all the types of cells in the body except for the tissues that surround the embryo..so they are not totipotent.

|
Stem Cell
|
an unspecialized cell that can give rise to one or more types of specialized cells. There are embryonic stem cells which are pluripotent and adult stem vcells which can produce new skin and blood cells. Adult stem cells are multipotent.
|
|
|
Mulitipotent
|
having the ability to produce many, but not all, kinds of differentiated cells. An example of multipotent cells are adult stem cells which can only produce new skin and blood cells.
