The outer ear, called the pinna, predominantly consists of muscle and cartilage, but the molecular mechanisms that shape the developing pinna remain poorly understood. In a new study, Juan Fons, Abigail Tucker and colleagues find that coordinated development of muscle and cartilage supports pinna formation, and investigate the molecular mechanisms underpinning this. To find out more, we spoke to first author Juan Fons and corresponding author Abigail Tucker, Professor at Kings College London, UK.
