HSC phenotype database

This database collates information on the hematopoietic phenotypes of knock-out mice as collected from the scientific literature. Entries have been curated by members of the Goodell Lab. For the most part, we have only included genes whose role in hematopoiesis has been tested by transplantation of bone marrow or stem cells from knockout mice into recipients. We encourage you to add your favorite genes and phenotypes into the database.
