Current Research Interest

Stem cells possess two fundamental properties; self-renewal and differentiation. Bone marrow-resident adult hematopoietic stem cells (HSC) respond to physiological stimuli and regenerate hematopoiesis. Dysregulated self-renewal and arrest in differentiation of HSC and progenitors induce leukemic transformation. From a translational perspective HSCs draw attention because of their potential use in stem cell and gene therapy. We are interested at understanding the cell-autonomous and non-cell-autonomous molecular determinants that regulate HSC self-renewal, differentiation and interaction with hematopoietic microenvironment or niche.

  1. Cell-autonomous mechanisms of hematopoietic stem cell transformation.
  2. Epigenetic regulation of leukemia stem cell heterogeneity.
  3. Microenvironment regulation in hematopoiesis
