Intussusception was first observed in neonatal rats. In this type of vessel formation, the capillary wall extends into the lumen to split a single vessel in two. There are four phases of intussusceptive angiogenesis. First, the two opposing capillary walls establish a zone of contact.
A cell wall is a structural layer that surrounds some cell types, ... (1882, 1889), and the intussusception theory by Julius Wiesner (1886). ...

Intussusception is an emergency requiring rapid treatment. [1] Treatment in children is typically by an enema with surgery used if this is not successful. [1] Dexamethasone may decrease the risk of another episode. [2] In adults, surgical removal of part of the bowel is more often required. [1] Intussusception occurs more commonly in children ...

The secretion of the vesicles at the growing tip anticipates the increase in growth rate, [75] indicating that the turgor pressure driven intussusception of the methylesterified pectin into the cell wall at the growing tip and its subsequent demethylesterification by pectin methylesterase may relax the cell wall by robbing the load-bearing ...
