Effect of Deep Space Radiation on Human Hematopoietic Stem and Progenitor Cell Function (NCC958IIH00404)
Principal Investigator
Research Area:
Cell and molecular biology
Radiation biology
Species Studied
Scientific Name: Homo sapiens Species: Human
Scientific Name: Mus musculus Species: Mouse

The original aims of this project were as follows: 1) Investigate the cellular consequences of exposing human hematopoietic stem (HSC) and progenitor (HPC) cells to an environment which simulates the radiation environment of deep space, 2) Examine the molecular consequences of exposing human hematopoietic stem cells to an environment which simulates the radiation environment of deep space, and 3) Design potential countermeasures to obviate or negate cellular and molecular damage discerned during the course of carrying out Aims 1 and 2.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
