Embryo-maternal relationships during the periimplantation period – new and old players

Blitek A. , Kaczmarek M.M. , Waclawik A. , Ziecik AJ. ,

This review attempts to integrate available data on embryo-maternal communication during maternal recognition of pregnancy and implantation in the pig. Progesterone (P4) is an essential hormone that makes the uterus receptive to accept conceptuses for implantation and subsequent placentation. As well as P4, the receptive stage of the endometrium is further primed by paracrine factors secreted by the conceptus prior to and during implantation. Oestro...

With the advent of next generation sequencing platforms (RNA-seq), transcriptional profiling permits the characterization of millions of RNAs from even the most limiting samples like early embryos. High-throughput RNA-seq can generate over 600 gigabases (Gb) in a single sequencing run, providing a near-complete record of all of the genes expressed in a sample at the time of collection. Condensing and finding coherence in the immense amount of raw data generated by transc...
