Invasive migration requires cells to break through extracellular matrix barriers, which is an energy-expensive process. In this issue, Park et al. (https://doi.org/10.1083/jcb.202402035) highlight the importance of biosynthesis of fatty acids, phospholipids, and isoprenoids in driving invasive migration of the Caenorhabditis elegans anchor cell through a basement membrane barrier during development.
