Each hepatocyte may have one, two or even three nuclei, meaning that there are probably less than 30 hepatocytes in this image.<br \/>\nPlace the cursor and remove or click on and off the image several times to check if you agree with the choice of the boundaries drawn by the author.<br \/>\n<\/div><\/div>\n<div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\">\n<div>\n<div class=\"image-container\">\n<p><a href=\"javascript:void(0)\"><br \/>\n  <img decoding=\"async\" src=\"https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/1-6.jpg\"\n       class=\"hover-image\"\n       data-original-src=\"https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/1-6.jpg\"\n       data-hover-src=\"https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/1-7MO.jpg\" \/><br \/>\n<\/a><br \/>\nLiver.
