in

The Basic Research Division of the Skeletal Biology Laboratory focuses on underlying mechanisms that govern the regulation of bone growth and homeostasis. This knowledge is utilized to design strategies to prevent or treat metabolic bone disease and bone cancer. Our research is performed using cell culture and animal models. Current specific research foci include:

  • Neuroendocrine regulation of body weight and bone metabolism.
  • Beneficial and detrimental effects of alcohol on bone.
  • Nutrition as a factor in tumor metastasis to bone.
  • Cross-talk between immune cells, fat cells, cancer cells, and bone cells.
  • Regulation of stromal (stem) cell differentiation into bone cells and fat cells
  • Effects of spaceflight/weightlessness on bone.
