Internalization and recycling of lutropin receptors upon stimulation by porcine lutropin and human choriogonadotropin in porcine Leydig cells.

abstract：:We took advantage of one of the main possibilities of ion microscopy, ie isotopic analysis, to study the cellular distribution of molecules labelled either with carbon 14 or with stable isotopes of low natural abundance such as nitrogen 15 and deuterium.
