RESIDENT CELLS – FIBROBLAST – MAST CELL
A fibroblast with an elliptical nucleus and its cytoplasm is shown. Observe the staining of its cytoplasm – it is bluish, basophilic. This means that this cell has a lot of ergastoplasm/ribosomes/RNA and is intensely active in synthesizing macromolecules.
Two other cells can be observed. One of them is a resident cell of the connective tissue that is not frequently stained by hamatoxylin/eosin, possibly a mast cell.
The other cell is a lymphocyte, a transient cell of the connective tissue. The lymphocytes have usually a small amount of cytoplasm around their the nuclei, and the cytoplsma is often not visible in histological sections.
The remainder of the image is occupied mostly by collagen fibers.
