Remodeling of uterine endometrial extracellular matrix (ECM) is pivotal to successful implantation and placentation, and has been well described in the rodents and humans. However, bovine endometrial ECM remodeling is still vaguely defined, especially at the time of implantation. Therefore, this study investigated the distribution of four ECMs namely, types I and IV collagen, laminin and fibronectin, from days 0 to 30 of gestation in bovine endometrium by immunofluorescence microscopy. A change in the distribution pattern of ECMs was evident by day 14 of gestation as features at this stage were clearly different from those of day 14 of the estrous cycle. The immunoreactivity of type I collagen, fibronectin and laminin decreased from day 14 of gestation and was obscured by day 24 of gestation. The type I collagen fibers formed were of thinner consistency than those of the estrous cycle and showed a coarser meshwork within the epithelium sites during the implantation period. In addition, the type IV collagen and laminin immunoreactivities of epithelial basement membrane also remarkably declined at exactly the same time. By day 30 of gestation, the four ECMs had regenerated with the formation of the placentome. In conclusion, this study reveals that remodeling of ECM is essential for the successful establishment of pregnancy in the bovine.
