Actin-based tubular connections between cells have been observed in many cell types. Termed "tunneling nanotubes (TNTs)," "membrane nanotubes," "tumor microtubes (TMTs)," or "cytonemes," these protrusions interconnect cells in dynamic networks. Structural features in these protrusions vary between cellular systems, including
