Abstract: Methods and compositions for directing adipose-derived stromal cells cultivated in vitro to differentiate into cells of the chondrocyte lineage are disclosed. The invention further provides a variety of chondroinductive agents which can be used singly or in combination with other nutrient components to induce chondrogenesis in adipose-derived stromal cells either in cultivating monolayers or in a biocompatible lattice or matrix in a three-dimensional configuration. Use of the differentiated chondrocytes for the therapeutic treatment of a number of human conditions and diseases including repair of cartilage in vivo is disclosed.

Abstract: The present invention provides methods and compositions for the consistent and quantitative differentiation of human preadipocytes isolated from adipose tissue into adipocytes bearing biochemical, genetic, and physiological characteristics similar to that observed in isolated primary adipocytes. The methods of the invention comprise incubating isolated human preadipocytes, plated at least about 25,000 cells/cm2, in a medium containing, glucose, a cyclic AMP inducer such as isobutylmethylxanthine or forskolin, a glucocorticoid or glucocorticoid analogue, insulin or an insulin analogue and a PPAR? agonist or a RXR agonist. The compositions of the invention include media for the differentiation of human preadipocytes, human adipocytes differentiated by the methods of the invention and transfected adipocytes.

Abstract: The invention relates to methods and compositions for the differentiation of stromal cells from adipose tissue into hematopoietic supporting stromal cells and myocytes of both the skeletal and smooth muscle type. The cells produced by the methods are useful in providing a source of fully differentiated and functional cells for research, transplantation and development of tissue engineering products for the treatment of human diseases and traumatic tissue injury repair.

Abstract: The invention provides methods for determining the ability of compounds to regulate lipogenesis and lipolysis by acting as a sulfonylurea-1 (SUR 1) potassium channel activator, an adipocyte potassium channel activator, an SUR 1 antagonist, and an adipocyte specific SUR 1 antagonist. The present invention recognizes the presence of the sulfonylurea receptor in adipocytes and its utility in identifying compounds and in regulating lipogenesis and lipolysis.

Abstract: The invention provides a composition of an isolated human adipose tissue-derived stromal cell that has been differentiated to exhibit at least one characteristic of a non-adipocyte cell lineage wherein the non-adipocyte cell lineage is osteoblastic. The adipose-derived cell possessing an osteoblastic characteristic can be genetically modified or combined with a matrix. The compositions of the invention can be used in vivo to repair bone and treat bone diseases.
