Background: Galaxy cannibalism/merging appears to be an important process through which galaxies grow in mass/size and evolve. There are many examples of ongoing collisions between two large galaxies and many involving the tidal disruption of a small (“dwarf”) galaxy by a large one. We have identified a rare case of a dwarf galaxy cannibalizing an…Continue Reading Studying a Rare Dwarf Galaxy Cannibalism Event

Flk2 Lineage Tracing Reveals a Novel, Developmentally-Restricted Hematopoietic Stem Cell
Using a recently characterized in vivo lineage tracing model, I have identified a novel fetal hematopoietic stem cell (HSC) that, although capable of supporting reconstitution of the blood system in an irradiated adult recipient, does not reside in the adult bone marrow in situ. This novel fetal HSC exhibits a differential lineage bias and gives…Continue Reading Flk2 Lineage Tracing Reveals a Novel, Developmentally-Restricted Hematopoietic Stem Cell
