H&E images obtained 12 weeks postoperatively in different groups: a defect without scaffold, b–d PLA, e–g PLA/G-nHA, and h–j PLA/G-nHA/PRP. The scaffold, bone, connective tissues, and defect site are signified by "S", "B", "C", and "D", respectively. The new bone islands are indicated by black arrows and osteocytes are identified in rectangles. The magnifications are × 40, × 200, and × 400 in (a, b, e and h), (c, f and i), and (d, g and j), respectively
