Hyperforin Impacts the Morphology of Melanoma Cells Morphological options acquired by melanoma cells immediately after 24 and 48 h treatment with low micromolar concentrations of HPF had been analyzed by microscopy examination. Figure two shows that HPF can have an effect on the organic shape of A375, FO-1, SK-Mel-28 and MeWo melanoma cells in 2D culture. Control cells turn out to become properly adherent to the plateInt.

Firstly, a cell proliferation assay was carried out by measuring Br-deoxy-uridine (BrdU) incorporation for the duration of the cell cycle DNA synthesis (S) phase. A375, FO-1 and SK-Mel-28 melanoma cells were treated with 2, three and four HPF for 48 h. At that time, BrdU was added for the culture medium and, soon after 8 h incubation, its incorporation.
