Cell-to-Cell communication: “The first kiss”

All living creatures communicate, including individual human cells that use thousands of wireless signals to talk to each other, such as cytokines and proteins. Immunofluorescence image of human embryonic kidney cells HEK-293 shows two cells communicating by extending their cellular projections towards each other and increased localization of cytoskeletal protein β-Tublin (shown as green) and methyltransferase protein SMYD5 (shown in red).
