Ystem originates from an academic research laboratory specialized in the study of stem cells, with particular regard to muscle regeneration. Years of experimental research have led up to the development of specific and optimized protocols for the extraction and purification of different stem cell populations. Besides, the formulation of cell culture media oriented to the improvement of stem cell proliferation has represented a further tool in this research field. The attention to the phenotypic characterization and genotypic expression of stem cells have generated a know-how focused on the application of these cells for the treatment of muscle degeneration in physiologic and pathologic processes.
