Health / Stem Cells
They are unique cells, turn into any specific cells, as the body needs them.
Sources of origination of stem cells
|
1. Adult body tissues
|
2. Embryos/ Embryonic stem cells
|
|
Supply new cells as an organism grows and to replace cells that get damaged.
|
supply new cells for an embryo as it grows and develops into a baby
|
|
Said to be multipotent , which means they can only change into some cells in the
body, not any cell.
|
Said to be pluripotent, which means they can change into any cell in the body.
|
The research on stem cells has shown that it can be present inside different
types of tissues ( the brain , bone marrow, blood and blood vessels , skeletal
muscles , skin , liver).
Types of Stem Cells:
|
Totipotent
|
means they can only change into some cells in the body, not any cell.
|
|
Pluripotent
|
means they can change into any cell in the body
|
|
Multipotent
|
They differ closely related family of cells. Adult hematopoietic stem cells,
for example, can become red and white blood cells or platelets.
|
|
Oligopotent
|
They differ into a few different cell types. Adult lymphoid or myeloid stem
cells can do this.
|
|
Unipotent
|
These can only produce cells of one kind and renew them. Examples are adult
muscle stem cells.
|
Uses
They can regenerate damaged tissue, under the right conditions.
Future Use
Used to replace cells & tissues that have been damaged or lost due to
disease.
