Abstract (original English)
This study describes the potential of the conditioned medium (CM) from adipose-derived mesenchymal stromal cells (ASCs) to affect the response of bone cells and support bone remodeling. This was in particular assessed by an in vitro model represented by a 3D human osteoblast-osteoclast co-culture. It has been reported that the effects of ASCs are predominantly attributable to the paracrine effects of their secreted factors, that are present as soluble factors or loaded into extracellular vesicles. They may affect various biological processes, including bone turnover. Our interest was to provide further evidence to support ASC-CM as a promising cell-free therapeutic agent for the treatment of bone loss. ASC-CM was characterized using nanoparticle tracking analysis (NTA), cytofluorimetry, and proteomic analysis. Human osteoblasts (hOBs) from vertebral lamina were cultured with monocytes, as osteoclasts (hOCs) precursors, in a Rotary cell culture system for 14 days. Histochemical analysis was performed to evaluate the effect of ASC-CM on bone-specific markers such as tartrate-resistant acid phosphatase (TRAP), osteopontin (OPN), RUNX2, Collagen 1 (COL1), and mineral matrix. ASC-CM characterization confirmed the content of CD63/CD81/CD9 positive extracellular vesicles. Proteomic dataset considering bone-remodeling-related keywords identified 16 processes significantly enriched. The
