FIG. 7.

70:30 col/PCL scaffolds degrade more rapidly than 50:50 col/PCL scaffolds. (A) Scaffolds were stained a fluorescent red with DiI and implanted into rat full-thickness skin wound defects. At 7, 14, and 26 days, tissue was harvested, sectioned, and imaged to assess degradation (n=5). (B) The area of the remaining fluorescent scaffold was analyzed using NIS Elements software. Student's t-tests were used to compare the area of remaining scaffold of the various groups for all time points. *Significantly different (p<0.05) than 50:50 scaffolds of the same day. ^Significantly different (p<0.05) than 7 and 14 days of the same group.
