Effect of partially purified P. linteus polysaccharide extract on the morphology of THP-1 cells. (a) THP-1 cells cultivated with 1 mg/mL P. linteus polysaccharide extract for 24 h. Cells show strong shrinkage, nuclear condensation and nuclear fragmentation into apoptotic bodies. Cells were stained with an AO/EB mixture and immediately photographed using excitation/emission at 485/530 nm using a 20× objective. (b) Control THP-1 cells.
