Biology of umbilical cord blood progenitors in bone marrow niches.
Within the bone marrow (BM), hematopoietic progenitor cells (HPCs) are localized in poorly oxygenated niches where they interact with the surrounding osteoblasts (OBs) through VLA4/VCAM-1 engagement, and are exposed to interleukin-6 (IL-6), stem cell factor (SCF), and chemokines such as CXCL12 (OB factors). Umbilical cord (UC) is more highly oxygenated that the BM microenvironment. When UC-HPCs...
متن کاملUmbilical cord blood transplantation
Since the first umbilical cord blood transplantation (CBT) in 1998, cord blood (CB) has now become one of the most commonly used sources of hematopoietic stem cells for transplantation. CBT has advantages of easy procurement, no risk to donor, low risk of transmitting infections, immediate availability and immune tolerance allowing successful transplantation despite human leukocyte antigen disp...
متن کاملUmbilical cord blood transplantation.
Umbilical cord blood transplantation (CBT) has been widely used as an alternative source of hematopoietic cell support for stem cell transplant patients. CBT offers several advantages over traditional stem cell sources, such as immediate availability, absence of risk for donors, lower risk of acute graft-versus-host disease, and a less stringent requirement for human leukocyte antigen matching....
متن کاملUmbilical cord blood transplantation.
Interest in umbilical cord blood as an alternative source of hematopoietic stem cells is growing rapidly. Umbilical cord blood offers the clinician a source of hematopoietic stem cells that are readily available and rarely contaminated by latent viruses. Moreover, the collection of umbilical cord blood poses no risk to the donor; there is no need for general anesthesia or blood replacement, and...
متن کاملPaediatric umbilical cord blood transplantation.
Umbilical cord blood is being used increasingly as a source of haematopoietic stem cells for transplantation because of rapid availability, and the unavailability of a HLA matched adult donor for some patients. This study reports the characteristics and outcomes of 15 patients who have undergone umbilical cord blood transplantation (UCBT) in Ireland between 1998 and 2009. The median total nucle...
