Prolactin Promotes Adipose Tissue Fitness and Insulin Sensitivity in Obese Males.

abstract：:Dispersed cells from whole testes or from isolated interstitial tissue of mature rats, yielded two distinct populations of Leydig cells when subjected to centrifugation in a 0-40% metrizamide gradient. One population (I) was found in a fractions with a density of 1.085-1.117 g/cm3, and the other population (II) was fo...
