Abstract
Compositions including a first soft tissue-derived matrix and a second soft tissue-derived matrix are provided, as well as methods of making such compositions. In some embodiments, the composition comprises dilapidated, decellularized adipose tissue-derived matrix and dilapidated, decellularized fascial tissue-derived matrix, which may be combined in various proportions. Such adipose-fascia matrix compositions provide improved volume retention when implanted into a patient. The composition may further include exogenous cells or other substances, and/or a carrier. The composition is suitable for use in plastic surgery procedures, including reconstructive or cosmetic surgery procedures, as well as procedures for wound treatment and tissue regeneration. The methods for making the compositions may involve separation of first and second soft tissues from one another, followed by performing one or more treatments on the separated soft tissues, then combining the treated soft tissues and, optionally, performing one or more additional treatments on the combined soft tissues.
