Leukemic stem cell biology
Dr. Gerber's research focuses on cancer stem cell biology, particularly in myeloid leukemias. His work involves the identification and characterization of leukemia stem cells in comparison to their normal counterparts, with the goal of identifying differences which can be clinically exploited. Leukemia stem cells, which typically constitute only a small minority of the total leukemic burden, are theorized to be responsible for disease relapse. These leukemia stem cells appear to be distinct from their offspring with respect to potential therapeutic targets and drug sensitivity profiles. Indeed, it seems existing therapies often kill only the bulk leukemic cells, while sparing the rarer and more resistant leukemia stem cells which are then capable of regenerating the disease. Clinically, this phenomenon may explain the significant disparities in leukemia (as well as in many other cancers) between remission and cure rates. The successful targeting of leukemia stem cells remains a critical step in the development of curative treatments for leukemia, which are more effective but less toxic than current options.
