Fig. 6From: High molecular weight of polysaccharides from Hericium erinaceus against amyloid beta-induced neurotoxicityMorphological changes in PC12 cells were induced by Aβ, and cells were protected by pretreatment with HEPS. a Morphological changes in PC12 cells were observed by microscope after incubation with 1.2 μM Aβ1–40 for 24 and 48 h. b PC12 cells were protected by HEPS (250 μg/mL) followed by incubation with 1.2 μM Aβ1–40 for 24 and 48 h. Intracellular fluorescence was observed by fluorescence microscopy. RPMI-1640 complete medium containing 10 % horse serum and 5 % fetal bovine serum are indicated as N+. Circles and arrows indicate nuclear fragments and cell rupture, respectivelyBack to article page
