Human adipose-derived stromal cells (ASCs) exhibit strong plasticity and proliferation potentials. In addition, ASCs are easy to harvest and are found at high frequency in adipose tissue samples. This gives us opportunities for their use in bone regeneration therapy. We thus evaluated the bone formation potential of ASCs in vitro and in vivo.ASCs were isolated from subcutaneous adipose tissue (following Local Ethical Guideline and after...

Objectives: The Brtl mouse, a unique model for the autosomal dominant forms of osteogenesis imperfecta was used to prove the feasibility of a lentiviral-shRNA-based strategy to improve collagen quality by targeting the mutant Col1a1 allele at the point mutation responsible for the causative substitution Gly349Cys. The ability to specifically suppress the mutant allele should convert the moderate Brtl outcome to the mild one caused by quantitative defect.<p class="...

Introduction: Conventional therapy of osteosarcoma, a primary malignant bone tumor, includes surgical excision with wide resection, which leads to physical and aesthetic defects. Allografts for reconstruction of bone and joints and adipose tissue autologous grafts for soft tissue defects can be supplemented with mesenchymal stromal/stem cells (MSCs). Additionally MSCs may be used in tumor-targeted cell therapy. However MSCs may have adverse effects on osteosarcoma development,...
