The Forsberg lab focuses on stem cell fate decisions of the blood system. Hematopoietic stem cells are responsible for generating a life-long supply of mature blood cells. Each stem cell is capable of making all of the mature blood cell types with widely different functions: some blood cells specialize in carrying oxygen, others fight off infections, and still others prevent bleeding in the process of blood clotting. How does a stem cell decide which cell type to give rise to? Are these decisions made by the stem cell itself, by its descendant multipotent progenitors, or both? How are these decisions dysregulated to cause cancer and other disorders?

We tackle these questions from multiple angles - by in vivo and in vitro experimental approaches, by focusing on specific molecules as well as analyzing global changes. Ultimately, we want to understand the molecular determinants of hematopoietic stem cell fate decisions so that we can prevent and treat both genetic and acquired disorders of the hematopoietic system, including anemia, autoimmune disease, leukemias and lymphomas.
