ABSTRACT
Development of viviparity in mammals requires that the placenta evolves as an intermediate interface between the fetus and maternal uterus. In addition to the retention of the fetus and secretion of nutrients to support growth and development to term, it is essential that viviparous species modify or inhibit the maternal immune system from recognizing the semi-allogeneic fetus. Following blastocyst hatching from its zona pellucida, trophoblast differentiation provides the initial communication to the maternal endometrium to regulate maintenance of progesterone production from the corpus luteum and biological pathways in uterine and conceptus development necessary in the establishment and maintenance of pregnancy. Many conceptus factors have been proposed to serve in the establishment and maintenance of pregnancy. CRISPR-Cas9 gene-editing technology provides a specific and efficient method to generate animal models to perform loss-of-function studies to investigate the role of specific conceptus factors. The utilization of CRISPR-Cas9 gene editing has provided a direct approach to investigate the specific role of conceptus factors in the development and establishment of pregnancy in the pig. This technology has helped address a number of questions concerning peri-implantation development and has altered our understanding of maternal recognition and maintenance of pregnancy in the pig.
