Intracellular Zn pools in human tumorgenic T47D cells are increased in response to prolactin (PRL). Zinc accumulation was visualized by immunofluorescence using FluoZin-3 in cells treated with PRL (d–f) and compared with untreated cells (a–c). Prolactin significantly increased well-defined cellular Zn pools (d–f), compared with untreated cells (a–c)
