Summary of Activity

Basic research

  • ・ Over 10 members have joined the Shinshu Univ. Biomedical Center for biomaterial research with a focus on carbon nanotubes
  • ・ Departmental collaborations at Shinshu Univ. School of Medicine to conduct research on bone, cartilage, muscle and nerve
  • ・ Collaborative research with the Institute of Fiber Engineering on spinal biomechanics
  • ・ Fiber biology, drug design for osteosarcoma, bone biology


Clinical research

  • ・ Cohort study to investigate musculoskeletal systems in the elderly
  • ・ Elucidate pathological conditions and find therapeutic strategies for extremity, spine, soft tissue and bone tumor, & osteoporosis
  • ・ Offer new treatments for elderly patients
  • ・ Show a bright future for child patients with musculoskeletal disorders
  • ・ Provide excellent quality of life (QOL) for people through sports and exercise
