Granule diffusion coefficients (D) and velocities.

Granule diffusion coefficients for diffusive-like motion and directed granule motion velocities for low and high glucose under various experimental conditions. “*” indicates that in diffusive populations, granules have significantly higher D upon glucose stimulation compared with low glucose samples (p<0.001, t test). “#” indicates diffusion coefficient or velocity are significantly lower than in control cells for the same stimulatory state (p<0.05, t test). “$” indicates that diffusion coefficient is significantly higher than in control cells for the same stimulatory state. Error term for D is defined as the square root of the 90% confidence interval [41]. Granule diffusion coefficients (D) and velocities.
