the present study was designed to ascertain , by in situ hybridization , whether adrenal chromaffin cells could synthesize anp , to define by an in vivo ultrastructural autoradiographic approach , whether anp could , in fact , bind to rat adrenal medulla cells , to determine whether there was a cellular [ noradrenaline ( na ) vs. adrenaline ( a ) ] selectivity in the binding process , and to establish whether extracellular [ 125i ] anp could be internalized by these cells .
