Bilateral ear punctures were made in 6-wk old mice and healing outcomes were measured after 30 d. At 8 wks of age, acute full-thickness articular cartilage injuries were introduced in the trochlear groove. Mouse knee joints were sectioned at indicated times post-injury and stained to evaluate regeneration. Time course analysis showed no significant regeneration until 16 wks post-wounding.

Summary of procedures that were conducted
• health assessment Post-injury wound healing. Ear cartilage and articular cartilage.
• histopathology Post-injury wound healing. Articular cartilage at 12wks and 16wks post-injury.
