The researchers found that
the endothelial layer was partially restored at 14 days and completely restored at 28 days post-balloon angioplasty in the group treated with the herpes virus.
One undesirable, yet expected outcome of angioplasty and stent placement is the disruption of the artery's
endothelial layer, which forms the inner lining of the artery.
Forty - eight hours after wounding,
the endothelial layer of cells (from the periphery all the way to the central area) showed considerable fluorescence due to BrdU incorporation.
Among other effects, immune cells disrupt the function of
the endothelial layer, the lining of the blood vessels, counteracting «all the good things that the endothelial cells produce,» says physiologist Brett Mitchell of Texas A&M College of Medicine in College Station.

To study this barrier and determine why a lack of blood flow causes it to leak, the researchers built a blood - vessel - on - a-chip model consisting of a channel lined with a
layer of human
endothelial cells surrounded by extracellular matrix within a microfluidic device, which allowed them to easily simulate and control the flow of blood through a vessel and evaluate the cells» responses.

layer, which is adjacent to the neurons of the brain, forms septate junctions, which function as a barrier to separate the humoral space and the brain, analogously to the mammalian tight junctions formed between
endothelial cells.

layer of mature podocytes that extend long cellular processes through the pores in the membrane and contact the underlying
endothelial cells.
