Diagram of the cardiac cycle highlighting phases 3 and 4, ventricular ejection: As the left ventricle remains contracted, the ventricular pressure (red line) peaks and begins to decrease as blood is ejected out of the ventricle. The phase coincides with the ST segment of the electrocardiogram fol...
including angiogenesis, and pericytes secrete exosomes containing miR-132. These exosomes stimulate angiogenesis by transferring miR-132 to endothelial cells (cells lining the inner surface of blood vessels) [154]. One of the most important mechanisms of miR-132 function...

This is followed by the proliferative phase, during which new cells and blood vessels are formed to rebuild the damaged tissue. Finally, in the remodeling phase, the newly formed tissue undergoes maturation and organization to restore its normal function. The success of wound healing depends on ...
It does this by alternating cycles of contraction and relaxation, in which the heart fills with blood and then ejects the blood into the blood vessels to be circulated throughout the body. What are the stages of the cardiac cycle? The cardiac cycle consists of two phases: systole and dia...
Alternatively, direct staining using fluorophore-conjugated markers, such as Griffonia Simplicifolia isolectin B4 and wheat germ agglutinin, can label blood vessels and cardiac sarcolemma, respectively. These markers usually have limited specificity, and their efficacy varies across tissues and species12,13...

2. either of the two lower chambers of the heart that receive blood from the atria and in turn force it into the arteries. 3. one of a series of connecting cavities of the brain. [1350–1400; Middle English < Latin ventriculus belly, ventricle. See venter, -i-, -cle1] Random ...
Currently, the primary treatment for myocardial infarction is opening blocked vessels to restore blood flow to the ischemic myocardium, which is called reperfusion. However, reperfusion can cause further damage to cardiac tissue, including cytokine production, neutrophil infiltration, and ROS production, ...
