Characteristics of tunneling nanotube-like structures formed by human dermal microvascular pericytes in vitro.

Tunneling nanotubes (TNTs) represent an innovative way for cells to communicate with one another, as they act as long conduits between cells. However, their roles in human dermal microvascular pericytes (HDMPCs) interaction remain elusive in vitro. In this work, we identified and characterized the TNT-like structures that connected two or more pericytes in two-dimensional cultures and formed a functional network in the human dermis.
