Isolated Cardiomyocyte

A fluorescence microscopy image featuring several isolated muscle cells (cardiomyocytes) glowing in a vibrant green against a black background. The cells are elongated with jagged ends, and a fine, striated pattern of internal structures is visible within the most brightly lit cell in the center. A $100\ \mu\text{m}$ scale bar is located at the bottom of the frame.

Description: We are studying the effects of common substances that can impact human cardiovascular health. In this picture, we are showing a cardiomyocyte that has been exposed to nicotine, an active compound found in cigarette smoke. We used fluorescence imaging to capture the cardiomyocyte that was loaded with Fura-2 a calcium indicator dye. Sometimes I can see these single cells still beating under the microscope!
