Previously, foetal sampling in the UK has only been permitted up to 22 weeks after conception (which is the legal deadline for termination), hindering the ability to study late-stage foetal development. As the stem cells collected by the researchers are sourced from the amniotic fluid, rather than the foetus itself, it allows a &#8216;bypass&#8217; of the legislation. <\/p>\n\n\n\n<p>The research paper, published this week (March 4th 2024) in <em><a href=\"https:\/\/www.nature.com\/articles\/s41591-024-02807-z#citeas\">Nature Medicine<\/a><\/em>, explains in detail the process of collecting stem cells from the amniotic fluid non-invasively, and culturing epithelial organoids that exhibit features reflecting their tissue of origin (i.e. small intestine, kidney and lung). <\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Stem cells collected in late pregnancy herald advances in prenatal medicine\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/D-0C1XTvDcM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p class=\"has-white-color has-black-background-color has-text-color has-background has-small-font-size\"><em>Video by Rajamanickam Antonimuthu explaining the process and potential of stem cell-derived &#8216;organoids&#8217; in prenatal medicine. <\/em><\/p>\n\n\n\n<p>This development is extremely exciting for prenatal medicine! The work provides a new opportunity to study late-stage foetal development (something which has not been possible before now), furthering knowledge and understanding. The organoids can also be used to model congenital disorders, extending knowledge on these, particularly in the later stages of development. Researchers now have the potential to develop new methods of diagnosis, prognosis and personalised therapy for congenital disorders, all because of a tiny little organ!<\/p>\n\n\n\n<p>I find this research inspiring and highly interesting, as well as hugely promising for prenatal medicine. Anything that can help reduce the morbidity and mortality of congenital disorders is a huge step in the right direction. The researchers have since expressed their vision to extend the method into the production of organoids from mesenchymal and haematopoietic tissues, allowing the treatment of a wider variety of diseases. I am excited to see how this develops, and, who knows, maybe these tiny organs will be the key to curing congenital birth defects!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Congenital disorders (more commonly known as congenital birth defects) contribute to a large portion of paediatric disabilities, and can persist into adult life, if the patient survives that long.
