The initiation of endochondral ossification starts by proliferation and condensation of mesenchymal cells in the area where the bone will eventually be formed. Subsequently, these mesenchymal progenitor cells differentiate into chondroblasts, which actively synthesize cartilage matrix components.
The Junqueira cow is a cattle breed from Brazil that is the result of crosses between Caracu and other Brazilian varieties. [1] It is of the subspecies Bos taurus ibericus [2] and has submetacentric Y chromosomes, suggesting it is of taurine origin. [3] The breed has been raised since the 18th century in São Paulo, but only about 100 remained ...
Studies conducted with 3D micro-CT on pig and human arteries from different vascular beds have shown that there are three different types of vasa vasorum: . Vasa vasorum internae, that originate directly from the main lumen of the artery and then branch into the vessel wall.

This approach (e.g., ViewRNA assays) can be used to visualize up to four targets in one assay, and it uses patented probe design and bDNA signal amplification to generate sensitive and specific signals. Samples (cells, tissues, and CTCs) are fixed, then treated to allow RNA target accessibility (RNA un-masking).
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein.
