Thin sections of uterine cervices from pregnant mice at day 6 and 18 of 19-days gestation period at different spatial locations along the cervices were studied with imaging Mueller polarimetry (IMP) combined with statistical analysis and multi-curve fit. The results suggest using depolarization and linear retardance images for collagen scoring and identification of cervical collagen changes during pregnancy. One day before delivery the remodeling of extracellular matrix of cervical collagen was detectable at the external cervical os, thus, proving that IMP modality may serve for the preterm birth risk assessment associated with the accelerated remodeling of cervical collagen.
