The morphological features and karyotype of hADSCs. The hADSCs are typical fibroblast-like cells with fusiform shape from the 3rd passage (P3) (A) to the 12th passage (P12) (B) (Bars = 100 μm). Under transmission electron microscope, hADSCs exhibited irregular nuclear morphology and abundant organelles (C), abundant microvilli with some inclusion body-like structures (arrow) (Bars = 500 nm) (D). (E) One of two reports from G-banding karyotype analysis at P12 showed normal female chromosome type: 46, XX.
