Histochemical analysis of cartilage regeneration in the defect area. (A,D) No detectable cartilage regeneration in the control group at both 15 d and 60 d post-implantation, (B,C) Reduced defect size with new cartilage formation at the treated zone within 15 d, and (E,F) Neo-cartilage formation with presence of formed lacunae at the treated zone 60 d post-implantation (a, b, d, and e are ×10 magnified images; c and f are ×20).
