Stress-relaxation proceeds faster with enzymatic digestion. Stress-relaxation data were normalized to a range between 1, representing the peak stress and 0 representing the equilibrium stress. Stress-relaxation proceeded faster after both enzymatic digestion (c-d) and incubation in HBSS (b). No major changes in the rate of stress-relaxation were observed in control samples samples maintained in tissue culture (a). Marked changes in the rate of stress-relaxation were observed after 1 day of incubation in bacterial hyaluronidase. Bars represent ± sem.
