Comparison of the rate of collagen gel contraction from day-3 to -5 between WT and SPARC−/− mouse conjunctival fibroblasts.

Values represent the mean % of initial gel sizes ± SD of 3 independent experiments, each performed in triplicate. The rate of contraction between day 3 and day 5 is evaluated as the difference in % of initial gel size between day 5 and day 3 over 2 days. The mean rate of contraction is the average of the rates of contraction of 3 independent experiments. The fold slower in rate is calculated based on mean rate of contraction from day 3 to day 5 of WT over SPARC−/− fibroblasts. *P = 0.01.
