Abstract
The invention provides a composition for promoting regeneration of tissue which has degenerated in a subject as a result of a disease or disorder and a method of using the composition is provided. The composition comprises a biodegradable acellular matrix, and passaged autologous fibroblasts substantially free of immunogenic proteins, c.g., culture medium serum-derived proteins, integrated within the matrix. Also provided is an injectable composition comprising an acellular filler material (e.g., any type of collagen) and passaged autologous fibroblasts substantially free of immunogenic proteins, e.g., culture medium serum-derived proteins, for correcting defects in skin, such as wrinkles or scars, and for augmenting tissue in the subject, particularly facial tissue.
