Regeneration of Osteonecrosis of Canine Scapho-lunate Using Bone Marrow Stromal Cells: Possible Therapeutic Approach for Kienböck Disease
Abstract:We evaluated the ability of canine bone marrow stromal cells (cBMSCs) to regenerate bone in a cavity of the scapholunate created by curretage and freeze–thawing with liquid nitrogen (LN). Autologous BMSCs were harvested from the iliac crest and expanded in vitro. Their potential to differentiate into osteo-, chondro-, and adipogenic lineages was confirmed using a standard differentiation induction assay. LN-treated scapholunates showed no regeneration of bone tissue when the cavity was left alone, demonstrating severe collapse and deformity as observed in human Kienböck disease. A combination of -tri-calcium phosphate and a vascularized bone graft with autologous fibroblasts failed to regenerate bone in the LN-treated cavity. When the same procedure was performed using BMSCs, however, LN-treated scapholunates showed no collapse and deformity, and the cavity was completely filled with normal cancerous bone within 4 weeks. These results suggested the potential of using BMSCs to treat Kienböck disease.

- Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
