Extracellular Matrix Remodeling in Follicle Regression Process
The Extracellular Matrix: The Follicle’s Structural Foundation Hair follicles do not float in empty space — they are embedded in a complex extracellular matrix (ECM) that provides structural support, signaling cues, and mechanical signals essential for follicle function.
