Core Insights - The collaboration between Hangzhou BGI Life Sciences Research Institute and Southern University of Science and Technology has resulted in the creation of a multimodal dataset that decodes the developmental process of animals, specifically generating a 3D single-cell spatiotemporal multi-omics atlas of the entire developmental cycle of fruit flies [1][2] - The research findings were published in the international academic journal "Cell," highlighting the molecular-level references for biological development and the potential foundation for studying developmental defects and related disease mechanisms [1][2] Group 1 - The research team utilized BGI's proprietary technology to sample fruit fly embryos at critical stages every 0.5 to 2 hours, generating over 3.8 million spatially resolved single-cell transcriptomes [2] - The "Spateo" algorithm was employed to reconstruct a high-precision 3D model, allowing for the precise analysis of spatial dynamics in tissue morphology and gene expression [2] - The study constructed a "differentiation trajectory map" of fruit fly embryonic development, elucidating key molecular mechanisms that determine cell fate [2] Group 2 - The research identified that different embryonic layer cells differentiate along specific pathways, with transcription factors acting as "directors" to activate or inhibit genes, guiding cells to perform specific roles [2] - Multiple previously unidentified transcription factors were found to potentially play critical roles in the nervous, intestinal, and endocrine systems [2] - Understanding the developmental processes and gene regulatory mechanisms in fruit flies, which share approximately 70% of disease-related genes with humans, can aid in exploring significant scientific questions related to life development and provide references for research in human developmental diseases [2]

据了解，此次下行的材料类实验样品后续将随返回舱运输回京，包括高强韧钢、月壤加固材料等4类22种。 太空生命科学实验 助力守护人类健康 为什么要在太空开展生命科学实验，这些生命科学实验样品将为我们揭开哪些"生命密码"呢？一起来了解。 央视网消息：4月30日13时08分，神舟十九号载人飞船返回舱在东风着陆场东区成功着陆，中国空间站第八批空间科学实验样品也随神舟 十九号乘组返回地球，生命类科学实验样品于30日晚顺利交付给科学家。 据记者介绍，这次随神舟十九号飞船下行的科学实验样品涉及空间生命科学、材料科学、新技术等多个领域的25个实验项目，总重量约 37.25公斤。在现场交付的实验样品主要是生命类科学实验样品，因为生物活性的特殊要求，这些样品是第一时间从着陆场转运到中国科学院 空间应用中心。现场交付的生命类科学实验样品包括骨细胞和成骨细胞、人支气管上皮细胞、蛋白样品及果蝇等20类，是空间站应用与发展阶 段下行生物样品种类最多的一次。此次下行的果蝇，跟斑马鱼、小白鼠一样是重要的模式生物，人类有约75%的致病基因都可以在果蝇身上找 到同源基因。神舟十九号乘组在轨期间，果蝇在空间站特殊装置内展开了"亚磁-微重力"实验。在 ...
