Sources of Stem Cells
Stem cells come from a variety of sources including blood, bone marrow, umbilical cord blood, and adipose tissue.
GE Healthcare supports cell-based research by providing quality tools that facilitate the preparation of healthy, undamaged cells.
In autologous bone marrow transplantation, bone marrow is extracted from bone and given back to the same person to replenish the hematopoietic stems cells, for example in leukemia patients. For research use, stem cells from the blood are easier to obtain.
Ficoll-Paque products are sterile, ready–to-use density gradient media used to produce different density preparations of mononuclear cells from peripheral blood, bone marrow, and umbilical cord blood by density gradient centrifugation.
Autologous cord blood cells can be collected and stored at birth, and safely infused back into the individual at a later stage, without the risk of immune rejection. The use of cord blood stem cells in treating conditions such as brain injury and type I diabetes is already being studied in humans.
AXP AutoXpress Platform, developed by ThermoGenesis Corp. and distributed by GE Healthcare, provides efficient recovery of viable stem cells. This automated, functionally closed, sterile system harvests the buffy coat from cord blood, reducing a unit of cord blood to a precise volume determined by the operator.
Adipose tissue is a rich source of adult stem cells. These multipotent stem cells can differentiate into many cell types, such as fat, muscle and bone cells, as well as cartilage and nerve.
