Figure 7.

At day 3, a small amount of greenish type III collagen deposits were observed in the CTR (a), GEL (b), and GELPG (c). At day 7, reticular type III collagen was seen in the CTR (d) and GEL (e), while parallel arrangements of type I collagen were seen in GELPG (f). At day 14, dense parallel arrangements of type I collagen were observed in the CTR (g) and GEL (h), whereas, in GELPG (i), the fibers were slightly interlaced. At day 21, gross, interlaced type I collagen fibers were seen in all of the groups, but they were less compact in the CTR (j) and GEL (k) than in GELPG (l) (Sirius Red/polarized light, 400× magnification).
