Effects of dynamin inhibitors on PpIX accumulation Cancer cells were incubated with 1 mM 5-ALA for 4 h in the presence of 1 μM to 16 μM MiTMAB, and then intracellular and extracellular PpIX accumulation was determined. (A) Intracellular PpIX; (B) extracellular PpIX. Data are expressed as the means ± S.D. of multiple experimental replicates (n = 3).
