8_20/2012Cellular Shuttles: Inter-endothelial Transport of Microvectors using Cellular Shuttles and Tunneling Nanotubes (Small 20/2012)

The transfer of material between cells includes macromolecules, organelles, and synthetic drug delivery vehicles. The cover image by B. Melendez and R. E. Serda is a pseudo-colored scanning electron micrograph showing cellular communication through tunneling nanotubes (TNTs). A silicon microparticle is shown engaged in cellular membrane folds, a process leading to cellular uptake. Despite the relatively large size of the microparticle, data presented by R. E. Serda and co-workers on page 3151 supports the transfer of microparticles between cells by means of TNTs.
