Photomicrograp showing a cell that produce the cartilage matrix, called chondroblasts or chondrocytes, depending on the relative maturity of the cells. Chondrocytes occupy small cavities in the extracellular matrix called lacunae. BEtween the chondrocyte and the extracellular cartilag matrix there is a pericellular matrix circumscribed by a ...

Photomicrograph of hyaline cartliage showing the specific disposition of chondrocytes bundled into the isogenic groups.
During embryogenesis, mesenchimal cells aggregate and differentiate into chondroblasts, which form centers of chondrogenesis that consists of chondroblasts surrounded by extracellular matrix. Chondroblasts divide by mitosis, and ...

This image of a section of hyaline cartilague shows chondrocytes located in matrix lacunae. Preparation for sectioning usually causes shrinkage of the matrix which may cause the chondrocytes to pull away from the matrix and become distorted. Note
the gradual transition and differentiation of cells from the perichondrium to the cartilague, with ...

Photomicrography of elastic cartilage shows perichondrium on both surfaces. Cell size and distribution in elastic cartilage is very similar to the hyaline cartilage. Note the presence of elastic fibers that provide greater flexibility to this form of cartilage.

Photomicrographs showing three hyaline cartilage staining method.

The photomicrograph shows brown adipose tissue. Brown adipocytes are slightly smaller and characteristically contain many small lipid droplets and central spherical nuclei (not show).

This photomicrograph shows adipocytes in the connective tissue associated with striated muscle tissue. The fat cells are very large, and empty because lipid dissolved away in slide preparation. Note the cell nuclei in a peripheral disposition.

White or unilocular adipose tissue is commonly seen in sections of many organs. In this photomicrograph adipocytes are seen in the connective tissue associated with blood vessels. The fat cells are very large, many with nuclei not present in the section, and are empty because lipid was dissolved away in slide preparation.

The most common manner to stain lipids is using the Sudan method that stain lipids present in the preparation. With this method we can differentiate the lipids presents in the slide. The rest of the preparation is transparent because it has not been dyed.

This interactive image shows a closeup of the parenchyma of the liver lobe in a semi-thin section of the rat liver stained with toluidine blue, showing the cells that compose it.
The hepatocytes are arranged adjacent and leave some small gaps between them. These spaces are called bile canaliculi and into them, hepatocytes excrete the bile. The ...
