Bioprinting of Complex Vascularized Tissues

2020
Functional vasculature is crucial for the maintenance of living tissues via the transport of oxygen, nutrients, and metabolic waste products. As a result, insufficient vascularization in thick engineered tissues will lead to cell death and necrosis due to mass transport and diffusional constraints.

Kallikrein release by vascular tissue

American Journal of Physiology-Heart and Circulatory Physiology, 1993
Vascular tissue contains kallikrein and kallikrein mRNA, suggesting a vascular kallikrein-kinin system. We questioned whether 1) kallikrein concentration varies among large and small vessels; 2) kallikrein is released by vascular tissue; and 3) blocking protein synthesis inhibits release, suggesting de novo synthesis.

Advances in vascular tissue engineering

Cardiovascular Pathology, 2003
Coronary and peripheral artery bypass grafting is commonly used to relieve the symptoms of vascular deficiencies, but the supply of autologous artery or vein may not be sufficient or suitable for multiple bypass or repeat procedures, necessitating the use of other materials.

Tissue engineered prefabricated vascularized flaps

Head & Neck, 2007
AbstractBackground.Microvascular free tissue transfer has become increasingly popular in the reconstruction of head and neck defects, but it also has its disadvantages. Tissue engineering allows the generation of neo‐tissue for implantation, but these tissues are often avascular.

Kininogenase from Rat Vascular Tissue

1986
A kininogenase resembling glandular kallikrein was partially purified from vascular tissue and characterized. Saline perfused rat tail arteries and veins were homogenized in 0.25 M sucrose containing 10 mM Tris-HCl (pH 7.4). The homogenate was centrifuged at 105,000 X g for 60 min and a vascular kininogenase was purified from the supernatant by ...

Catecholamine biosynthesis in vascular tissue

Experientia, 1970
Die Umwandlung von Tyrosin in Katecholamin wurde in verschiedenen Blutgefassen untersucht. Die Katecholamin-Biosynthese erfolgte am schnellsten in der Arteria mesenterica sup. (0,6 μg/g/h), was zehnmal hoher liegt als diejenige in der Aorta oder in der Arteria pulmonalis.

Engineering vascularized skeletal muscle tissue

Nature Biotechnology, 2005
One of the major obstacles in engineering thick, complex tissues such as muscle is the need to vascularize the tissue in vitro. Vascularization in vitro could maintain cell viability during tissue growth, induce structural organization and promote vascularization upon implantation.

Angiotensin receptors in vascular tissue

The American Journal of Medicine, 1976
The biologic effect of angiotensin II is triggered by its interaction with components of target organs, which specifically recognize the hormone. These receptors have been studied with the use of radioactive angiotensin and, as for other peptidic hormones, have been localized in the plasma membrane of target cells. Such angiotensin receptors have been

Vascular tissue development in plants

2019
The plant vasculature is a sophisticated system that has greatly contributed to the evolution of land plants over the past few hundred million years. The formation of the vascular system is a well-organized plant developmental process, but it is also flexible in response to environmental changes.

CORTICOSTEROIDS AND VASCULAR CONNECTIVE TISSUE

Acta Endocrinologica, 1969
ABSTRACT Male albino rabbits were injected with prednisone 2 mg/kg body weight, daily for two weeks. The aortic content of acid mucopolysaccharides and the synthesis of sulphated acid mucopolysaccharides decreased, whereas the collagen content remained unchanged as compared to the saline injected controls.
