Research Focus
Haemopoietic stem cell niche biology.
Overview
The Niche laboratory’s research interests stem from a desire to understand the role of the haemopoietic microenvironment in stem cell biology. This is essential to be able to maximise as well as manipulate haemopoietic stem cell (HSC) potential in both normal and disease states. Considerable evidence supports the proposal that the localisation of haemopoiesis to the bone marrow involves developmentally regulated adhesive interactions between stem cells and the stromal cell mediated haemopoietic microenvironment of the marrow. We have focused our research on the lodgement of cells once they trans-endothelially migrate into the bone marrow, and the adhesion molecules on HSC and within the haemopoietic microenvironment that influence this process. We have recently developed methodologies to be able to assess engrafting transplanted cells at the single cell level and are beginning to identify key adhesion molecules that not only regulate this process, but also have effects on HSC survival, growth and differentiation. Specifically, our research focuses on identifying and characterising the mechanisms involved in attracting, retaining, regulating and releasing HSC from the stem cell niche.
