Stem cells are collected from donors through two main methods.
Methods of Stem Cell Collection
Peripheral Blood Stem Cell Collection
- Process: Blood is taken from a vein and circulated through a specialized machine.
- Machine Function: This machine separates and collects the stem cells.
- Return of Blood: After the stem cells are removed, the remaining blood and plasma are returned to the donor.
Bone Marrow Stem Cell Collection
- Procedure: This method requires a minor surgical procedure performed in an operating room.
- Collection Point: Stem cells are collected from the bone marrow, which is the soft center of the bone.
- Collection Method: A needle is used to extract the stem cells directly from the bone marrow.
Summary Table
| Collection Method | Description |
|---|---|
| Peripheral Blood Stem Cell Collection | Blood is circulated through a machine to separate and collect stem cells; remaining blood is returned. |
| Bone Marrow Stem Cell Collection | Stem cells are extracted using a needle from the soft center of the bone (marrow) in an operating room. |
Both methods are important for various medical treatments where stem cells are needed for transplantation or other therapeutic purposes.
