A number of fundamental biological processes, ranging from fertilization and embryonic development to viral infection, depend upon a complex interplay between cells that results in the fusion of their plasma membranes. Surprisingly, the cellular and molecular mechanisms underlying cell-cell fusion remain largely unknown. Here, the authors discuss evidence suggesting that microvilli play a central role in fusion of many cells and present features of these actin-filled, a cell-surface protrusions that might make them particularly well suited as cell-fusion organelles.
