In anatomy and histology, the term wandering cell (or ameboid cell) is used to describe cells that are found in connective tissue, but are not fixed in place. The papillary layer contains a large number of capillary arches, extending to the epidermal-dermal contact point. Mast cells are distributed in connective tissues, often adjacent to blood vessels and beneath epithelial surfaces (e.g. It is named so because it takes the form of fine threads crossing each other in every direction leaving small spaces called areolae.

Rachel Rush Columbia, Mast cells are found in mucosal and epithelial tissues throughout the body. See if you can identify some of the cells, with the labels off. Mast Cells are found close to small blood vessels in loose connective tissue. They also contain histamine, which promotes an inflammatory reaction when secreted. Fibroblasts Cells (Fibrocytes): Fibroblast is an active cell. Indirect Proof Logic Examples, Mast Cells. The principal cell of connective tissues is the fibroblast. They are mainly responsible for secreting the non-rigid extracellular matrix including the fibres: collagen, elastin or fibronectin.

Fibroblasts Cells (Fibrocytes): Fibroblast is an active cell. One may, however, hypothesize that keloid formation could be a result of an abnormal response to tissue injury, hence resulting in an exaggerated inflammatory state characterized by entry of excessive inflammatory cells into the wound, including macrophages, lymphocytes, and mast cells. Mast cells are found principally in mucosae and in connective tissue, generally clustered at epithelial surfaces and around nerves and blood vessels [3]. These APCs can phagocytose infected cells and tumor cells, place them in phagosomes, and degrade them with lysosomes. This term is used occasionally and usually refers to blood leukocytes (which are not fixed and organized in solid tissue) in particular mononuclear phagocytes.
