Analysis of PTH secretion and intracellular Ca<sup>2+</sup> after prolactin treatment.

<p>A) Measurements of PTH secretion from parathyroid adenoma cells upon treatments with prolactin at 100 µg/L or 200 µg/L. Results from four independent experiments are shown. B) Example of a measurement of intracellular Ca<sup>2+</sup> in parathyroid adenoma cells treated with 100 µg/L followed by 200 µg/L prolactin, as indicated by vertical red lines.</p>
