The morphology of the ELs from ovarian cancer induced by hypoxia and microdissected by LCM. The ovarian cancer cells were cultured in 3-dimisonal Matrigel system on EVA membrane under hypoxia for 7 d before harvest. The pictures were taken under the light microscope. A and B. The original and after microdissected by LCM of the single cell. C and D. The original and after microdissected by LCM of the grouped cells. Magnification X200. Arrow: The morphology of the cells after microdissection.
