title: Bidirectional myoblast-pericyte plasticity.
abstract: Microvascular pericytes are able to generate multiple mesenchymal cell types, including skeletal muscle myoblasts. Cappellari et al. (2013) report in this issue of Developmental Cell that myoblasts can return the favor by generating pericytes via the action of Dll4 Notch ligand and PDGF-BB.
