title: [Presence of nuclear triiodothyronine (T3) receptors in mouse fibroblasts].
abstract: The present preliminary data obtained from intact fibroblasts of adult mice (polyploid stem L 929) suggest that this cell system possesses high-affinity and saturable nuclear binding sites for triiodothyronine. As estimated by the Scatchard analysis, the equilibrium dissociation constant is approximately 2 X 10(-10) moles, the maximal binding capacity is about 2 000 sites for T3 per cell nucleus.
