Group Leader - A/Prof Stephen Ting
A/Prof Stephen Ting is a Haematology clinician-scientist based at Alfred Health-Monash University. He is an active practising haematologist and a principal investigator studying self-renewal pathways of haematopoeitic and leukemia stem cells.

Tissue-specific stem cells replenish the mature, functional cells of that tissue throughout the life of the organism. Self-renewal and cell quiescence are important properties of normal stem cells that must be tightly regulated to maintain homeostasis. The goal of the Stem Cell Research Group is to understand the regulation of self-renewal and cell quiescence in normal HSCs and how these processes are perturbed in acute leukaemia. This research has broad therapeutic implications for ex vivo expansion of stem cells for bone marrow transplantation or regenerative medicine and identifying new ways of killing quiescent leukemic stem cells.
