Abstract

Methods are described for generating autologous tissue grafts, including generating grafts at the point of care, which include isolated cell populations that are enriched with stem cells and are mixed with biological fillers including hyaluronic acid and derivatives thereof. The hyaluronic acid localizes the cells to a desired injection site and stimulates collagen production thus enhancing the viability and the longevity of the graft.
