Ultrastructural features of SN-MM cell lines. TEM images show SN-MM cell morphology (A–C, G–I) and melanosomes (black arrows) at different stages of development including early (E, F) and mature (J–L) melanosomes. A well-developed Golgi apparatus is also shown (D). Scale bars are 10 µm (G, I), 5 µm (A, B, C, H), 2 µm (D, F, J) and 1 µm (E, K, L)
