Research Data Supporting Biomechanical and Compositional Changes in the Murine Uterus with Age

The uterus is a hollow, fibromuscular organ involved in physiological processes such as menstruation and pregnancy. The content and organization of extracellular matrix constituents such as fibrillar collagen dictates passive (non-contractile) biomechanical tissue function; however, how extracellular matrix composition and biomechanical function change with age in the uterus remains unknown. This study utilizes Raman spectroscopy coupled with biaxial inflation testing to investigate changes in the murine uterus with age (2-3 months, 4-6 months, 10-12 months, and 20-24 months).
