Fate decision of hematopoietic stem cells by Wnt signaling

Abstract

Over the past 15 years, many studies have revealed that Wnt signaling has a strong impact on hematopoietic stem cell fate. After a controversy over the interpretation of some results, the current understanding is that an appropriate degree of canonical Wnt signaling induces hematopoietic stem cell self-renewal and that noncanonical Wnt signaling keeps the quiescence. It is also likely that the balance between canonical and noncanonical Wnt pathways regulates the stress response and aging of hematopoietic stem cells.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
