abstract：:In the murine Ob 17 preadipocyte cell line, the thyroid hormone T3 is an adipogenic factor necessary at an early stage for differentiation into adipocyte. We demonstrate here that this T3 dependence may involve a transient expression (at both the messenger RNA and the protein levels) of c-ErbA beta-type receptors (T3R...
