Description of research
One of the simplest and most provocative concepts in all of stem cell biology is how a single stem cell can give rise to both copies of itself as well as daughter cells that can give rise to any of the highly specialized cell types of a given tissue. As a population, this decision making process must exist in a tightly regulated balance in order to avoid tissue degeneration (too few stem cells) or progression to cancer (too many stem cells). Many malignancies are thought to arise from a mutation or series of mutations in a single stem cell that goes on to cause an overproduction of cells eventually leading to cancer. Our lab focuses on how aberrant cell fate choice drives malignancy on a single cell level.
Our current research is focused on three main themes in adult blood stem cell biology:
1) Molecular drivers of blood stem cell heterogeneity
2) The early stages of cancer evolution from single cells
3) Blood stem cell expansion outside the body
The Kent lab is grateful for research funding from Bloodwise, the European Research Council, the European Hematology Association and the Rosetrees Trust. Students and postdocs have received funding from the Wellcome Trust, BBSRC, MRC and Danish Lundbeck Foundation.
