Analysis of Radiographs and Biosamples from Primate Studies (COS 1887-27)
Principal Investigator
Research Area:
Skeletal physiology
Species Studied
Scientific Name: Macaca mulatta Species: Monkey Strain: Rhesus


The present experiment was designed to serially study the growth and development of the juvenile primate peripheral skeleton, and to determine if a two-week period of space flight affected this development. This design was chosen because in the juvenile primate (3-5 kg), the skeleton is still undergoing rapid development at this stage, with longitudinal growth at the unfused metaphyseal-epiphyseal junctions, and periosteal and endosteal architectural modeling. This provides the possibility to detect an effect of microgravity by a change in the normal rate of growth and modeling.
