Musculoskeletal Research Training Program (T32)

This NIH training program boasts a group of highly qualified mentors in state-of-the-art research environments, providing an ideal modern setting for training young scientists.

2nd Annual Combined T32 Symposium - U of MN/Mayo - October 4, 2017 


Symposium program and more 

The University of Minnesota has a long and rich tradition in training individuals to study musculoskeletal biology and disease. The research strengths of the training program are in the areas of animal models for bone cancer research and osteoarthritis, outcomes-based research for orthopaedic and bone cancer treatments, adult stem cell research, molecular biology and genomics research.

Our goals:

  • Train predoctoral students and postdoctoral fellows for research careers as basic scientists or clinical investigators studying the causes and treatments of musculoskeletal diseases
  • Develop an educational environment for students and postdoctoral fellows, which encompasses a modern spectrum of research in musculoskeletal diseases, including basic discovery, investigation of musculoskeletal disease models and study of outcomes of standard treatments. 


The strengths of musculoskeletal research at the University of Minnesota are in the areas of basic discovery, mechanisms of musculoskeletal disease in animal models and outcomes-based research of standard clinical treatments. These strengths are found in the four primary focus groups. 

These focus groups allow for and encourage cross-disciplinary interactions between molecular biologists, (stem) cell biologists, orthopaedic surgeons, veterinary researchers and bioengineers. The primary interests of each faculty member guided his/her placement into the groups; however, many faculty members make significant contributions to more than one focus group.

Musculoskeletal Cancer Biology and Therapeutics

(D.R. Clohisy,* M. Garwood, D. Largaespada, J. Modiano)

The collective focus of this group is to understand the etiology, progression and clinical sequelae of musculoskeletal cancers and to develop new therapies for treatment and prevention; specific areas of research include the cellular mechanisms regulating osteolysis in cancer; bone cancer-associated pain and tumor metastasis to bone; animal models of sarcoma; clinical epidemiology research in osteosarcoma and rhabdomyosarcoma; and the development of new techniques in MR imaging and oncology.

Osteoarthritis and Cartilage Biology Group

(C. Carlson,* J. Bechtold, P. Ludewig, G.E. Pluhar)

This group has a common interest in understanding the etiology and treatments of osteoarthritis. Specific areas of research include the development and validation of animal models of osteoarthritis; bone fracture repair; biomechanics of the shoulder joint; and the pathophysiology of degenerative osteoarthritis of the spine.

Musculoskeletal Development Group

(R. Gopalakrishnan, D. Kaufman, K. Mansky, L. Potter, M. O'Connor)

This group is unified by the common interest of understanding the molecular mechanisms that regulate skeletal development, maturation, and differentiation. Specific areas of research include osteoblast and osteoclast biology and the role of these cells in the physiologic and pathophysiologic formation of the skeleton; mechanisms involved in limb regeneration in xenopus tadpoles; skeletal aberrations occurring in dwarfism; and estrogen signal transduction cascades in bone metabolism and cancer biology.

Epidemiology and Clinical Outcomes Research Group

(L. Spector*, M. Swiontkowski)

This group of investigators applies state-of-the-art epidemiologic and clinical outcomes research methodologies to critically evaluate a wide variety of musculoskeletal treatments. This group has multiple strengths but the two most important are their access to large patient/sample populations through cooperative multi-institutional trials and their international reputation in orthopaedic-based clinical outcomes research. Specific areas of research include the assessment of functional outcomes for the treatment of musculoskeletal conditions and the etiology and behavior of musculoskeletal cancers.

Emily Bermel
Department: Biomedical Engineering 
Graduate Program: Biomedical Engineering
Appointment Date: July 1, 2016
Mentor: Victor Barocas, PhD
Project Description: My research deals with the lumbar facet capsular ligament (FCL). The FCL guides and constrains spinal motions such as flexion/extension, lateral bending, and axial rotation. It is comprised of highly aligned collagen fiber bundles on the posterior surface and nonaligned elastin fibers on the anterior surface. My goal is to develop a theoretical/computational model of the degeneration process using growth and remodeling theories in conjunction with realistic models of the tissue geometry and properties. 

Nicholas Blixt
Department: Developmental & Surgical Sciences 
Graduate Program: Molecular, Cellular, Developmental Biology & Genetics
Appointment Date: May 1, 2016
Mentor: Kim Mansky, PhD
Project Description: I am researching the molecular mechanisms behind how histone deacetylase enzymes regulate osteoclast differentiation. The end goal of this research is to provide mechanistic insight into controlling osteoclast differentiation as potential new therapy for osteoporosis or other diseases characterized by uncontrolled bone loss. This compliments my main research interests, which involve elucidating the transcriptional and epigenetic profiles among cell types that produce and maintain the skeletal system, as well as how the skeleton is modeled and remodeled based on the activity of these cells. 

Branden Smeester 
Department: Pediatrics
Graduate Program: Comparative & Molecular Biosciences 
Appointment Date: May 1, 2016

John Looft, PhD
Department: Physical Medicine & Rehabilitation 
Appointment Date: July 1, 2016
Mentor: Paula Ludewig, PhD
Project Description: Developing a high fidelity shoulder finite element model for clinical applications. The goal of this model is to combine finite element models along with MRI and fluoroscopy to develop predictive models for diagnosing shoulder pain and dysfunction. Additionally working on collaborative research projects improving MRI auto-segmentation software for clinical applications.

Department: Physical Medicine & Rehabilitation 
Appointment Date: January 1, 2017
Mentor: Dawn Loe, PhD
Project Description: Advancing the musculoskeletal field by investigating how estrogen affects the inflammatory responses and strength recovery following traumatic muscle injury, and how we can utilize our research to develop therapeutic strategies to prevent, lessen, regain, and finally improve muscle strength in females with low levels of circulating ovarian hormones. I’m also interested in the therapy strategies with bone marrow transplantation and recombinant enzyme modifying behavioral and musculoskeletal impairment in Hurler mice, a mouse model for Hurler Syndrome (or MPS I-H).

Project Description: My primary research aim is to develop a biomechanical model based in kinematic data that will help establish a foundation for a clinical examination of movement impairments for people with shoulder pain.

We believe this model will result in a more specific diagnostic paradigm from which doctors and physical therapists base their interventions.
