Cellular Integrity

Meaning

Cellular integrity describes the structural and functional soundness of a cell, particularly its plasma membrane, organelles, and genetic material. This state signifies a cell’s robust ability to maintain its internal organization, regulate transport across its boundaries, and execute its specialized physiological duties without compromise. A high degree of cellular integrity is a prerequisite for tissue function and resistance to stressors like oxidative damage or pathogen invasion. Compromised integrity, conversely, is a hallmark of aging and chronic disease states, impacting everything from hormone production to immune response.
