RT-PCR results showing (A) osteoblast cadherin expression in Day 5 gels treated with octanol, (B) connexin-43 expression in Day 5, Day 5-loaded, Day 30, and Day 5 long-term gels without communication inhibitors, (C) connexin-43 expression in Day 5 gels treated with octanol, (D) differences in connexin-43 expression between short and long-term recovered Day 5 gels treated with octanol, and (E) connexin-43 expression in Day 5, 15, and 20 long-term recovered gels loaded with octanol. Asterisks show significant differences at α=0.05.
