If all goes well, it grows strong until it breaks out of the egg into the world.<\/p>\n\n\n\n<p>In the<a href=\"https:\/\/www.embl.es\/research\/unit\/trivedi\/index.html\"> Trivedi Group<\/a> at EMBL Barcelona, Krisztina Arat\u00f3 and Jia Le Lim study the early development of zebrafish embryos. As the structure of the embryo grows more complex, a contractile network made up of two proteins \u2013 actin and myosin \u2013 helps cells rearrange. To understand how this process works, the researchers must examine embryos that are stripped of their protective outer layer.<\/p>\n\n\n\n<p>In this image, myosin appears in green on the embryo&#8217;s surface, labelled with green fluorescent protein (saturated pixels are in red), while the bulk of the embryo shows as a blue halo in a different focal plane. When Krisztina Arat\u00f3 saw this embryo after a night of live imaging, she realised something had gone wrong.<\/p>\n\n\n\n<p>Despite standard sterilisation procedures, a microbial invader had managed to sneak into the medium and attack the embryo. Some embryonic cells had already undergone apoptosis \u2013 a form of programmed death that can occur in response to stress, for example during an infection. Here, large punctuated patches of myosin reveal dying cells.<\/p>\n\n\n\n<p>The two researchers had to take a closer look to figure out what had happened. They captured this striking scene \u2013 resembling a satellite image of the Earth \u2013 with a multiview light-sheet microscope (MuVi-SPIM).<\/p>\n\n\n\n<figure class=\"vf-figure wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"702\" class=\"vf-figure__image\" src=\"https:\/\/wwwdev.embl.org\/news\/wp-content\/uploads\/2020\/02\/potw2008_news_large-1024x702.png\" alt=\"\" class=\"wp-image-18509\" srcset=\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2020\/02\/potw2008_news_large-1024x702.png 1024w, https:\/\/www.embl.org\/news\/wp-content\/uploads\/2020\/02\/potw2008_news_large-300x206.png 300w, https:\/\/www.embl.org\/news\/wp-content\/uploads\/2020\/02\/potw2008_news_large-768x526.png 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"vf-figure__caption\">Credit: Krisztina Arat\u00f3, Jia Le Lim and the<a href=\"https:\/\/www.embl.es\/services\/mesoscopic-imaging-facility\/\"> Mesoscopic Imaging Facility<\/a>\/EMBL<\/figcaption><\/figure>\n\n\n\n<p>If you have a stunning picture of your science, your lab, or your site, you can submit it <a href=\"mailto:mathias.jaeger@embl.de\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the Trivedi Group at EMBL Barcelona, Krisztina Arat\u00f3 and Jia Le Lim study the early development of zebrafish embryos.<\/p>\n","protected":false},"author":76,"featured_media":18508,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[6,17591],"tags":[497,563,11022,679,931],"embl_taxonomy":[19389],"class_list":["post-18507","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-picture-of-the-week","category-science-technology","tag-barcelona","tag-embryonic-development","tag-spotlight","tag-trivedi","tag-zebrafish","embl_taxonomy-trivedi-group"],"acf":{"article_intro":"","related_links":false,"article_sources":false,"description_pdf_archive_link":"","pdf_archive_link":"","vf_locked":false,"featured":false,"color":"#15153b"},"embl_taxonomy_terms":[{"uuid":"a:3:{i:0;s:36:\"302cfdf7-365b-462a-be65-82c7b783ebf7\";i:1;s:36:\"18a7a17b-e276-4afd-b0ca-8ddac1883d45\";i:2;s:36:\"365161ee-79a9-4010-8e7b-948e597af400\";}","parents":[],"name":["Trivedi Group"],"slug":"trivedi-group","description":"What &gt; Tissue biology and disease modelling &gt; Trivedi Group"}],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Accidental beauty | EMBL<\/title>\n<meta name=\"description\" content=\"This image shows the patterns of a protein, myosin, in the cells of a zebrafish embryo.
