Morphological observation of hDPs (passage 3) and ihDPs (passages 5, 10, 15, 25, and 50) using phase-contrast microscopy. Scale bars: 300 µm (A). Evaluation of stem cell surface markers using flow cytometry (B). Multilineage differentiation potential toward osteogenic lineage. Scale bars: 300 µm (C). Oil red O staining after adipogenic induction. Scale bars: 30 µm (D).
