histo-, hist-, histi- +

1. A cell or group of cells capable of forming tissue.
2. One of the precursor cells that give rise to the tissues of the body; usually in the embryo and fetus, but also later in life.

1. The chemistry of body tissues; especially, in the sense of the characterization of the distribution of specific chemical compounds within cells.
2. The location of particular chemical compounds within tissues by the use of specific staining techniques; for example, phloroglucinol to stain lignin.

The treatment of disease with chemical compounds or drugs.

Any of several diseases involving the reticuloendothelial system.

1. Pertaining to the breakdown or resorption of tissue by cells.
2. The ability to break down tissues, said of certain cells.

1. The extent to which an organism's immune system will tolerate tissue grafts from another organism.
2. A compatibility between the genotypes of donor and host such that a graft generally will not be rejected.

Normally, a graft from an unrelated individual is recognized as foreign by the recipient's white blood cells because the marker molecules (self-antigens) on the surface of the foreign cells differ from the recipient's marker molecules; therefore, the white cells are stimulated to mount an immune response against the foreign tissue.

Only certain close relatives share the same self-antigens, and can tolerate grafts of each other's tissues. The most important of these self-antigens are proteins coded by a complex cluster of genes called the Major Histocompatibility Complex (MHC).

Marked by histocompatibility; not likely to induce an immune response lading to rejection; said especially of a tissue graft or organ transplant.

A connective-tissue macrophage; a cell found in many tissues in the body which is derived from the blood monocyte and which has an important role in host defense mechanisms.

It phagocytizes and kills many bacteria and is the site of infection for a number of intracellular parasites.

Any of several disorders in which there is a proliferation of histocytes without any known underlying cause; such as, infection, or a disorder of lipid metabolism.

Histocytosis may be solitary or multiple, and may be restricted to bone or may be generalized.

The diagnosis of disease processes by means of microscopic examination of the affected tissues and cells.

Disintegration of a tissue caused by conditions other than infection.

1. The development of the characteristics peculiar to a particular tissue type from less organized groups of cells.
2. The process of cellular maturation in which a primitive cell develops into specific cellular tissue types.

Fluorescence produced in tissue by the administration of some substance; such as, one that was previously irradiated.

1. The development of the special characters of the tissue of an embryo or of the developing organ of an adult.
2. The creation and development of tissues arising from undifferentiated embryonic cells.

Histogenesis involves the formation of multinucleate fibers and striations of muscle and of collagen and fibroblasts in the skin.

A reference to histogenesis (the origin and development of tissue).
