Research Focus

The objective of our research is development of innovative cell therapies based on haemopoietic stem cells.

Overview

The overall focus of the laboratory is to dissect the intrinsic and extrinsic aspects of haemopoietic regulation that are attributable to haemopoietic stem cell (HSC) and the HSC niche. Specifically, this involves defining molecules comprising the HSC niche, as well as the mechanisms involved in attracting, retaining, regulating and releasing HSC from the niche.

An understanding of these mechanisms will allow us to develop strategies for constructing an artificial niche recapitulating the interactions evident in situ.

This will provide opportunities to gain a further insight into the mechanisms influencing HSC within the niche, as well as the potential to manipulate HSC ex vivo for therapeutic purposes. A longer term goal is to encompass the collaborative development of bioreactors for large scale HSC manipulation. A comprehensive understanding of the HSC niche as well as the mechanisms involved in HSC regulation will allow us to more critically analyse aberrant haemopoiesis, and specifically leukaemia. Furthermore, an understanding of the HSC niche will allow us to collaboratively analyse other stem cell niches, both normal and neoplastic.
