Figure 4. Data demonstrating the pulp cell-mediated contraction of the collagen-glycosaminoglycan matrices. (a) Graph showing the reduction in diameter of the non-seeded and cell-seeded matrices with time in culture. Mean ± SEM. For the cell-seeded samples: 0 (n = 24), 1 (n = 24), 7 (n = 18), 14 (n = 12), and 28 (n = 6) days. For the non-seeded samples, n = 6. The error bars are smaller than the symbols used for the means. (b) Graph showing the DNA content of the matrices with time in culture (Mean ± SEM; n = 4). (c) Bar chart showing the cell-mediated contraction normalized to DNA content of the matrices. Mean ± SEM. 1 (n = 24), 7 (n = 18), 14 (n = 12), and 28 (n = 6) days.
