News - Complete human day 14 post-implantation embryo models from naïve Embryonic Stem Cells

Carnegie Stage 6 Embryo

This recent Nature paper^[1] describes the use of naïve human Embryonic Stem Cells to recapitulate the early stages of human development.

"The ability to study human post-implantation development remains limited due to ethical and technical challenges associated with intrauterine development after implantation....only genetically unmodified human naïve human ES cells...recapitulate the organization of nearly all known lineages and compartments of post-implantation human embryos including epiblast, hypoblast, extra-embryonic mesoderm, and trophoblast surrounding the latter layers...These human complete SEMs demonstrated developmental growth dynamics that resemble key hallmarks of post-implantation stage embryogenesis up to 13-14 days post-fertilization (dpf) (Carnegie stage 6a)."

+This recent Nature paper{{#pmid:37673118|PMID37673118}} describes the use of naïve human Embryonic Stem Cells to recapitulate the early stages of human development.
-<br>"Residential proximity to major roadways, and prenatal exposures to particulate matter <2.5 μm (PM2.5) and ozone (O3) are linked to poor fetal outcomes but their relationship with childhood development is unclear. We investigated whether proximity to major roadways, or prenatal and early-life exposures to PM2.5 and O3 increase the risk of early developmental delays. 4089 singletons and 1016 twins born between 2008 and 2010. Proximity to major roadway was calculated using road network data from the NY Department of Transportation. Concentrations of PM2.5 and O3 estimated by the Environmental Protection Agency Downscaler models were spatiotemporally linked to each child's prenatal and early-life addresses incorporating residential history, and locations of maternal work and day-care. In this prospective cohort study, proximity to major roadway and prenatal/early-life exposures to PM2.5 and O3 were associated with developmental delays. While awaiting larger studies with personal {{air pollution}} assessment, efforts to minimize {{air pollution}} exposures during critical developmental windows may be warranted."
