CELLS OF THE HAEMOPOIETIC SYSTEM
Haemopoietic Stem Cells
|
•
|
All blood cells are derived from the haemopoietic stem cell (HSC). |
|
•
|
The HSC is a multipotent cell with extensive self-renewal and proliferative capacity that can differentiate into progenitors of all blood cell types. |
|
•
|
estimated that HSC's comprise 0.01 to 0.05% of the total marrow cell population in humans. |
|
•
|
stem cell transplantation, HSC and haemopoietic progenitor cells can be harvested by multiple bone marrow aspirations under general anaesthesia |
|
•
|
Harvested HSCs and progenitor cells are infused through a vein into the circulation of the recipient, from where they are able to "home" to the bone marrow to reconstitute the haemopoietic system. |

|
New evodence points out to the capability of these cells to produce other types of tissues such as kidney cell. |
