RESIDENT CELLS – FIBROBLAST – 1
The type of connective tissue that has been analyzed so far in this chapter is the most common type of non-specialized connective tissue, called Connective tissue proper. It is found in the skin, inside and around organs, and in the walls of blood vessels, and in many other places of the body.
The most common cell of this tissue is the fibroblast. It is the most frequent cell in the image to the side, whose elongated nuclei are observed even at low magnifications.
The fibroblast is a very important cell for the function tissue (and for the organism as a whole), as it synthesizes and secretes most of its extracellular matrix and also digests and reabsorbs the matrix. In addition, the fibroblast controls the quantity and quality of the matrix, obeying signals emitted by the organism or signals originating locally.
Look carefully at this image – there are two main components distinguish:
1 – collagen fibers, acidophilic, stained pink by eosin. These fibers vary in size, thickness and direction.
2 – fibroblasts, which are the majority of the cells present in this image. They are recognized by their elongated nuclei, since their cytoplasm is often very thin.
