Evidence for Functional Roles of MicroRNAs in Lineage Specification During Mouse and Human Preimplantation Development.
Proper formation of the blastocyst, including the specification of the first embryonic cellular lineages, is required to ensure healthy embryo development and can significantly impact the success of assisted reproductive technologies (ARTs). However, the regulatory role of microRNAs in early development, particularly in the context of preimplantation lineage specification, remains largely unknown. Taking a cross-species approach, this review aims to summarize the expression dynamics and functional significance of microRNAs in the differentiation and maintenance of lineage identity in both the mouse and the human. Findings are consolidated from studies conducted using in vitro embryonic stem cell models representing the epiblast, trophectoderm, and primitive endoderm lineages (modeled by naïve embryonic stem cells, trophoblast stem cells, and extraembryonic endoderm stem cells, respectively) to provide insight on what may be occurring in the embryo. Additionally, studies directly conducted in both mouse and human embryos are discussed, emphasizing similarities to the stem cell models and the gaps in our understanding, which will hopefully lead to further investigation of these areas. By unraveling the intricate mechanisms by which microRNAs regulate the specification and maintenance of cellular lineages in the blastocyst, we can leverage this knowledge to further optimize stem cell-based models such as the blastoids, enhance embryo competence, and develop methods of non-invasive embryo selection, which can potentially increase the success rates of assisted reproductive technologies and improve the experiences of those receiving fertility treatments.
期刊介绍:
The Yale Journal of Biology and Medicine (YJBM) is a graduate and medical student-run, peer-reviewed, open-access journal dedicated to the publication of original research articles, scientific reviews, articles on medical history, personal perspectives on medicine, policy analyses, case reports, and symposia related to biomedical matters. YJBM is published quarterly and aims to publish articles of interest to both physicians and scientists. YJBM is and has been an internationally distributed journal with a long history of landmark articles. Our contributors feature a notable list of philosophers, statesmen, scientists, and physicians, including Ernst Cassirer, Harvey Cushing, Rene Dubos, Edward Kennedy, Donald Seldin, and Jack Strominger. Our Editorial Board consists of students and faculty members from Yale School of Medicine and Yale University Graduate School of Arts & Sciences. All manuscripts submitted to YJBM are first evaluated on the basis of scientific quality, originality, appropriateness, contribution to the field, and style. Suitable manuscripts are then subject to rigorous, fair, and rapid peer review.
