Bonus BioGroup is a product-focused biotechnology company applying proprietary technology to supply tissue-regenerating, viable bone grafts. The company develops cell therapy and tissue-engineering products based on autologous bone implants that enable efficient bone transplantation and provide cell-based bone replacement for repairing bone lesions. Bonus BioGroup is the developer of BonoFill, a method for growing high-density 3D bone grafts based on multicell 3D cultures. BonoFill is derived from the patients own cells and constructed from a variety of cells grown in multiple layers within a bioreactor system. BonoFills technology enables the construction of bone grafts outside of the human body (ex vivo) and promotes graft acceptance by the patients body following transplantation. It also allows growth of a human tissue graft tailored to the biological, physical, and clinical needs of each patient, without incurring immune reactions or graft rejection.
