EXPERIMENT INFORMATION

Electron Microprobe Analyses of Calcium, Sulfate, Magnesium, and Phosphorous Distribution in Incisors of Spacelab-3 Rats (SL3 BSP6)
Principal Investigator
Research Area:
Skeletal physiology
Species Studied
Scientific Name: Rattus norvegicus Species: Rat Strain: Sprague-Dawley

Description
Objectives:

This experiment was to determine if the microgravity of space flight altered the normal patterns of mineralization during amelogenesis and dentinogenesis in the rat incisor, a tissue which preserves a thirty-day record of growth in its concentric growth increments. Ca, S, Mg, and P distributions were determined to assess mineralization patterns.
