Intercellular Matrix (Stratum Corneum) (SC Intercellular Matrix)

Target
SC Intercellular Matrix
Molecular classification
Lipid Matrix, Extracellular Matrix, Lipid Bilayer, Protein Matrix
01

Overview

The intercellular matrix of the stratum corneum is the lipid-rich extracellular material filling the spaces between corneocytes. It is composed primarily of ceramides, cholesterol, and free fatty acids, organized into multilamellar structures. This matrix is crucial for maintaining the skin's barrier function, preventing water loss, and protecting against external insults such as pathogens, toxins, and mechanical stress. Disruption of this matrix leads to skin disorders characterized by impaired barrier function.
