Effect of polysaccharides on cell proliferation of NIH/3T3 cells NIH/3T3 at 37°C in the absence (○) or presence of 10 (△), 100 (■) or 1000 μg/ml (◆) of Porphyridium sp. polysaccharide or 100μg/ml of either dextran cells were seeded at a concentration of 0.5 × 10⁶ cells per 9.6-cm² plate and incubated sulfate (●) or carrageenan (□). Data are mean ± SD, (n = 4).
