Lipocartilage cells, a newly identified cell type, provide cushioning and structural support similar to bubble wrap in various body parts, including the ear and nose. Unlike typical fat cells, these cells don't play a metabolic role, as their size remains constant despite diet changes. They contain large lipid-filled vacuoles, contributing to tissue flexibility. This discovery challenges the conventional understanding of tissue stiffness regulation, typically controlled by the extracellular matrix. The study offers unprecedented insights into these cells' structure and function and their existence in many mammals.
