Uptake of pyridoxine as a function of concentration in primary human pancreatic acinar cells (hPACs). Cells were incubated at 37°C in Krebs-Ringer buffer at pH 7.4 in the presence of different concentrations of pyridoxine. Uptake by the saturable component was calculated as detailed in materials and methods. Data are means ± SE of 3–4 separate uptake determinations.
