Abstract: Aspects of the technology disclosed herein generally (and in part) relates to use of Angiogenin (ANG) for increasing hematopoietic reconstitution of in vivo hematopoietic cells and transplanted hematopoietic cells. Provided herein are methods and compositions useful in treatment of diseases characterized by decreased levels of hematopoietic cells, decreased levels of hematopoietic reconstitution, blood cell deficiency and prevention and treatment of radiation injury. One aspect relates to angiogenin treated hematopoietic cell compositions and methods of their use in stem cell transplantation. Treatment of hematopoietic cells with angiogenin enhances quiescence and reduces proliferative capacity of primitive hematopoietic stem cells while increasing proliferation of myeloid restricted progenitor cells. Another aspect relates to use of ANG in prophylactic and therapeutic treatment methods for radiation injury.
