Moreover, tissue preserved in cell block can be readily shared for second opinions and research without fear of losing the original diagnostic smear specimen. In fact, the cells of most plant cells can be grown in culture media. tissue for cell block can increase both diagnostic sensitivity and specificity (through both cellular morphology and ancillary testing). Cytokeratin 19 immunostaining of cell block preparations of thyroid aspirates serves as a useful tool for the diagnosis of papillary carcinoma.

Just like in mitosis, the parent cell uses this time to prepare for cell division by gathering nutrients and energy and making a copy of its DNA. 1 2 3 All known living things are made up of one or more cells. Given that several other widely used cell block preparation methods were also reported to have high rates of user dissatisfaction, 9 we embarked on experiments to improve cell capture in cell blocks in our laboratory.
