In vitro formation of endothelial cells into capillary-like cords is promoted by keratocytes

When isolated bovine capillary endothelial cells were co-cultivated with rabbit corneal keratocytes, capillary-like cords extended actively from the capillary endothelial cells in multilayers of keratocytes. The developing cords continued to elongate, branch out and anastomose with each other, forming a capillary-like network by the 12th day of co-culturing. Electron microscopic observation revealed that the cords had tubular structures, which were composed of 3-8 endothelial cells in the multilayers of keratocytes, and that a basal-like matrix was situated on the outer surface of the endothelial cells. The roles of keratocytes in the cord formation by capillary endothelial cells were discussed. This simple in vitro experimental system is proposed as a useful tool in the study of corneal neovascularization.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
