_________ link extracellular matrix to keratin intermediate filaments.
ExplanationIn hemidesmosomes, integrins attach to ECM proteins called laminins in the basal lamina, which is the ECM secreted by the epithelial cells. Integrins link ECM to keratin intermediate filaments. Hemidesmosomes are important in maintaining the structural stability of epithelial cells by anchoring them together indirectly through the extracellular matrix.
