H&E staining of the junction of primary rib (red triangular arrow) and scaffold (green triangular arrow). (A) (×10) The primary rib and scaffold of the PDO/DBM/BMSCS group. No clear borderline was observed in the junction of the primary rib and scaffold. (B) (×40) At the junction of primary rib and scaffold of PDO/DBM/BMSCS group, marrow (black arrow) and new bone were observed; (C) (×10) In the primary rib and scaffold of the PDO/DBM group, a clear borderline was observed at the junction. (D) (×40) In the junction of the primary rib and scaffold of PDO/DBM group, fibrous tissue (blue arrow) was found both in the junction and in the scaffold.
