TL;DR: The morphofunctional characteristics of CD34+ stromal fibroblastic/fibrocytic cells (CD34+ SFCs) are reviewed and their in vivo behaviour during proliferation and differentiation in different physiologic and pathologic conditions is explained.

TL;DR: Human resident CD34+ SC/TCs in the enteric wall have progenitor capacity and are activated with or without differentiation into αSMA+ stromal cells during inflammatory/repair processes.

TL;DR: Inter intestinal TCs have a phagocytic‐like property, a function that may be generalized to TCs in other locations, and this function (the ability to internalize small particles), together with the capacity of these cells to release extracellular vesicles with macromolecules, could close the cellular bidirectional cooperative circle of informative exchange and intercellular interactions.

TL;DR: Intussusception participates in the formation of the meshwork of processes in LN sinuses during LN development, which contributes to the general knowledge of intussusceptive lymphangiogenesis, provides a basis for further studies and supports a new role for vessel intussUSception (formation of an intraluminal meshwork with known action in fluid filtering, cell interactions and immunology.

TL;DR: The ultrastructure of myopericytes makes it possible to distinguish them from pericytes, SMCs, and fibroblast/myofibroblasts, which is useful forMyopericytoma diagnosis, and supports an intermediate form between pericytic and muscular microvasculature.
