Tracking the fate of cancer-stromal hybrids.

Abstract

<p>Representative morphologies of the hybrid cells during colony formation are shown. <b>A</b>, Two weeks into the culture, most of the hybrids contained two nuclei of similar fluorescence. No cell division was observed. <b>B</b>, Four weeks into the co-culture, hybrid cells adopted atypical morphology with multiple nuclei. No cell division was observed. <b>C</b>, Six weeks into the culture, the remaining hybrid cells became thin or narrow, with multiple nuclei in segments of the cell. <b>D</b>, Eight weeks into the culture, cell division became prevalent. The cell division was abnormal because it produced daughter cells in varied shapes and with reduced viability. For each view, a phase contrast image (top) and red fluorescence image (bottom) are shown. When necessary, arrows are used to indicate nuclei. All the images are shown at 200× magnification.</p
