Pathways for transport of choline by human placental epithelia were investigated using brush border membrane vesicles isolated by divalent cation precipitation. The presence of choline transport mechanisms mediating Na(+)-choline cotransport, choline/H+ exchange and facilitated diffusion were assessed from [3H]choline tracer flux measurements. The rate and magnitude of intravesicular choline accumulation was unaffected by the imposition of an inwardly directed Na+ gradient suggesting an absence… CONTINUE READING
