Figure 5From: Cytotoxicity effect of degraded and undegraded kappa and iota carrageenan in human intestine and liver cell lines Morphology observations before and after MGG staining of Caco-2, FHs 74 Int, HepG2 and Fa2N-4 cells following exposure to degraded k -carrageenan. Cells were seeded at a cell density of 2 × 105 cells per ml and incubated for 24 h. A (a-h) Untreated cells. B (a-h) Cells treated with FGKC; 5C (a-h) Cells treated with DKC; 5D (a-h) Cells treated with CGKC and 5E (a-h) Cells treated with tamoxifen at the IC50 values for 72 h were observed for apoptotic morphological characteristics. Treated cells showed chromatin condensation (blue arrow), microspike formation (green arrow), nuclear fragmentation (yellow arrow) and apoptotic bodies (red arrow).Back to article page
