Fenestrations almost exclusively develop in older plants, so a Monstera grown from seed that has only popped out a few fresh sprigs of growth won’t develop fenestrations for a long time… somewhere near three years! And, even in an older plant, not every leaf will come out fenestrated.
Does the glomerulus have Fenestrations?
Glomerular capillaries and fenestrae Intriguingly, glomerular endothelial cells have cell cytoskeleton-associated transcytoplasmic pores, called fenestration, that are approximately 60–70 nm in diameter.
Is glomerulus fenestrated?
The glomerular capillaries are lined by a fenestrated endothelium that sits on the glomerular basement membrane, which in turn is covered by glomerular epithelium, or podocytes, which envelops the capillaries with cellular extensions called foot processes. In between the foot processes are the filtration slits.
Where does the word fenestration come from?
