Fig. 2From: Growth environment and organ specific variation in in-vitro cytoprotective activities of Picea mariana in PC12 cells exposed to glucose toxicity: a plant used for treatment of diabetes symptoms by the Cree of Eeyou Istchee (Quebec, Canada)Comparison of cytoprotective and mitogenic activities of P. mariana needle (●), bark (■) and cone (▲) extracts in PC12-AC grown in hyperglycemic media. MANOVA analysis was used to average all extracts based on their organ type and concentration. Significant cytoprotection (*) or mitogenic activity (#) was afforded when Dunnett post hoc tests were p ≤ 0.05 as compared to the normoglucose (C) and high glucose (HG) controls. All organs showed significant protection at all concentrations except cone at 2 μg/mL (needle n = 120, bark n = 60, cone n = 18)Back to article page
