Tunica media changes in the spontaneously hypertensive rat (SHR)
Atherosclerosis, 1987The histological, ultrastructural, morphometrical and histochemical aspects of the arterial media were studied in young and aged SHR, and compared to normotensive Wistar Kyoto rats. The diffuse thickening was the most characteristic feature of the hypertensive media. It seems due to three processes: Early generalized hypertrophy of smooth muscle cells (

The Medicolegal Significance of Proteoglycans in the Tunica Media of the Vertebral Artery
The American Journal of Forensic Medicine and Pathology, 1993After an apparently minor blow to the neck, the vertebral artery may rupture, with a fatal outcome. It is medico-legally important to assess whether the structural state of the artery is normal and, if not, whether this abnormality contributed significantly to the individual's death.

The aortic tunica media in aging rats
Experimental and Molecular Pathology, 1970Abstract The tunica media of aortas of female breeder rats ranging in age from 5–36 months were examined by light and electron microscopy. Similar material previously obtained from newborn to 3-month-old female rats was used for light microscopy. Aortas were fixed at their physiological lengths.

The early development of the tunica media in the vascular system of rat embryos
Anatomy and Embryology, 1990The use of a monoclonal antibody (HHF-35) against muscle-cell-specific actin has led to new insights into the early development and differentiation of the tunica media of blood vessels. The localization of this substance was studied by light and electron microscopy, in 22 rat embryos ranging between 10 and 15 days post coitum.

Several studies have already described the presence of specialized niches of precursor cells in vasculature wall, and it has been shown that these populations share several features with mesenchymal stromal cells (MSCs). Considering the relevance of MSCs

The Tunica media of the Thoracic Duct Contains a Heterogeneous Population of Muscle Cells
Cells Tissues Organs, 1994The three-dimensional cyto-architecture and ultrastructure of cells composing the different regions of the tunica media of canine and feline thoracic ducts (ThD) were investigated by scanning and transmission electron microscopy. The tunica media of the intervalvular regions consists of 2-4 layers of circularly oriented ribbon-like smooth muscle cells (

Although aortic or cardiac complications are common in patients with Marfan syndrome, the presence of an intracranial aneurysm is comparatively rare. In this study, the authors report on their experience with resection of a ruptured fusiform aneurysm of ...

Circumferential Alignment of Muscle Cells in the Tunica media of the Human Brain Artery
Journal of Vascular Research, 1983Our purpose was to measure how structurally coordinated is the network of muscle cells in the brain artery. Vessels from 7 autopsies were fixed with glutaraldehyde and formalin at physiologic pressure. We embedded each artery alongside a block of liver, formed into a rectangular prism, prepared it for light microscopy and stained the sections with ...

The turnover of newly formed proteins in the aortic myocyte was studied by means of quantitative light and electron microscopic radioautography. Adult and young mice were sacrificed at long intervals between 4 h and 108 days after one injection of tritiated leucine.

MULTIPLE PERIPHERAL ANEURYSMS ASSOCIATED WITH NONSYPHILITIC DEGENERATION OF THE TUNICA MEDIA
Archives of Surgery, 1937While multiple small aneurysms of the cerebral and of the pulmonary vessels have been discovered at necropsy, and multiple aneurysms of various of the individual intra-abdominal arterial trunks have been found at operation and at postmortem examination, but relatively few cases of multiple peripheral aneurysms have been reported.
