The Armstrong laboratory is focused on the mechanisms of cancer development with a focus on leukemia. One major interest in the lab is the relationship between leukemia, normal hematopoietic stem cells and the various hematopoietic cells of origin of leukemia. The lab is also studying the role of histone modifications and chromosome Read more about Scott Armstrong, MD, PhD

The step-by-step differentiation of embryonic cells into different types of neurons lays the foundation for our sensory responses, motor commands, and cognitive behaviors. Our research explores such differentiation programs in mammals using a combination of genetic, embryological, and molecular biological methods. While the generation of such neural diversity is a complex process culminating in the most sophisticated of wiring circuits, one simplifying approach is to start by tracking the specification, differentiation, and migration paths taken by specific sets of cells originating from primitive neuroectoderm.

Allogeneic hematopoietic stem cell transplantation (HSCT) is widely used in the treatment of patients with hematologic malignancies, but continues to be associated with severe toxicities. Both the effectiveness and toxicity of HSCT are mediated by donor T-cells in the stem cell graft. Those T cells that target antigens expressed on recipient leukemia cells play an important role in eradicating residual tumor cells and preventing leukemia relapse after transplant. In contrast, T cells that target antigens expressed by normal tissues in the recipient are the primary mediators of graft versus host disease (GVHD) and thus lead to substantial toxicities. My laboratory focuses on the assessment of donor immune function after HSCT and characterization of the immune mechanisms responsible for graft versus leukemia (GVL) and GVHD.

Stem cells are rare and unique cells capable of generating many different types of cells needed in the body. In adult tissues, different organs contain different stem cell populations, each of which produces a subset of the body's cells. For example, hematopoietic (blood-forming) stem cells generate all of the red and white blood cells needed to deliver oxygen to body tissues, fight infection, and stop bleeding. Similarly, myogenic (muscle-forming) stem cells generate mature muscle fibers necessary for controlled contraction of skeletal muscle. Work in the Wagers Lab focuses on understanding the mechanisms that regulate the function of these blood-forming and muscle-forming stem cells so that their potential can be optimally exploited for the treatment of diseases such as cancer, anemia, muscular dystrophy, and diabetes.
