Accidental or deliberate ionizing radiation exposure can be fatal due to widespread hematopoietic destruction. However, little is known about either the course of injury or the molecular pathways that regulate the subsequent regenerative response. Here we show that the Wnt signaling pathway is critically important for regeneration after radiation-induced(More)
Hematopoietic regeneration following chemotherapy may be distinct from regeneration following radiation. While we have shown that epidermal growth factor (EGF) accelerates regeneration following radiation, its role following chemotherapy is currently unknown. We sought to identify EGF as a hematopoietic growth factor for chemotherapy-induced(More)
Graft-versus-host disease (GVHD) complicates half of hematopoietic stem cell transplants (HCT), and the gastrointestinal tract is commonly affected. Endoscopic biopsies have a key role in the diagnosis. The optimal procedure(s) to perform and site(s) to biopsy remain unclear. We retrospectively analyzed the charts of all adult patients who underwent(More)
