A variety of TGF-β superfamily members affect adipocyte differentiation and function with consequential effects on energy metabolism. There has been a growing interest in this area because of the apparent influence of the BMP subgroup on brown adipose characteristics and potential application to the treatment of human obesity. In this chapter we describe methods that are useful in allowing one to assess the roles of specific members of the superfamily on adipocyte differentiation and mature adipocyte function, including the isolation and differentiation of mouse embryo fibroblasts (MEFs) to examine cell autonomous effects and the efficient transfection of two commonly used (but difficult to transfect) adipogenic cell lines, C3H/10T1/2 and 3T3-L1.
