Lactation driven dynamics of adiponectin supply from different fat depots to circulation in cows.

abstract：:We have determined the binding affinity and capacity and relative distribution of epidermal growth factor (EGF) receptors in the skin of the Merino sheep fetus before and during the development of the wool follicle population. Autoradiography of tissue sections incubated with [125I]EGF revealed that label was confined...
