Preparation of an adipogenic hydrogel from subcutaneous adipose tissue

Abstract

The ability to generate controlled amounts of adipose tissue would greatly ease the burden on hospitals for reconstructive surgery. We have previously shown that a tissue engineering chamber containing a vascular pedicle was capable of forming new fat; however, further refinements are required to enhance fat formation. The development and maintenance of engineered adipose tissue requires a suitable source of growth factors and a suitable scaffold. A hydrogel derived from adipose tissue may fulfil this need. Subcutaneous fat was processed into a thermosensitive hydrogel we refer to as adipose-derived matrix (ADM). Protein analysis revealed high levels of basement membrane proteins, collagens ..
