Figure 1From: Human adipose tissue-derived multilineage progenitor cells exposed to oxidative stress induce neurite outgrowth in PC12 cells through p38 MAPK signalingConditioned medium from hADMPCs exposed to oxidative stress induces neurite outgrowth in PC12 cells. (A, B) Decrease of the reduced/oxidized glutathione ratios and increase in the intracellular ROS levels in hADMPCs treated with BSO. hADMPCs were treated with 1 mM BSO for 16 h, and cellular GSH/GSSG levels (A) or ROS (H2O2) levels (B) were analyzed. (C-G) Induction of neurite outgrowth in PC12 cells by conditioned medium from BSO-treated hADMPCs. PC12 cells were induced to differentiation by changing medium to differentiation medium alone (C), CM-BSO (−) (D), CM-BSO (+) (E), or differentiation medium with NGF (50 ng/mL) (F) for 2 days. Scale bars, 200 μm. (G) One hundred individual neurites were measured in each sample using Dynamic Cell Count Analyzer BZ-H1C (Keyence, Osaka, Japan) and average neurite length was calculated. **, P < 0.01 (Student’s t test). (H) Percentage of neurite-bearing PC12 cells. A cell was scored positive for bearing neurites if it has a thin neurite extension that is double the length of the cell body diameter. A total of 500–600 cells in each sample were counted. **, P < 0.01 (Student’s t test).Back to article page
