华大最新Cell论文：时空组学新技术，破解FFPE样本难题，看清宿主-微生物“战场全景”

Core Viewpoint - The article discusses the breakthrough of a new spatial transcriptomics technology, Stereo-seq V2, developed by a Chinese research team, which enables high-resolution, in-situ analysis of host-microbe interactions in FFPE samples, unlocking vast clinical data for research and diagnostics [3][4]. Breakthroughs - Breakthrough 1: Unlocking 90% of Clinical "Treasures" - Over 90% of clinical samples are FFPE, which have been difficult to analyze due to RNA degradation. Stereo-seq V2 can analyze samples preserved for up to 9 years, providing detailed spatial maps of tumor gene expression [8][9]. - Breakthrough 2: Random Primers as a "Universal Key" - Unlike traditional methods that only capture mRNA, Stereo-seq V2 uses random primers to capture the entire transcriptome, significantly increasing the number of detected genes and allowing for precise identification of tumor-specific splicing events [10][11]. - Breakthrough 3: In-situ Capture of Pathogens and Immune Cells - Stereo-seq V2 allows for simultaneous capture of all human and microbial RNA, enabling comprehensive analysis of host-microbe interactions without prior knowledge of the pathogen [12][13]. - Breakthrough 4: Wide Clinical Applications - The technology has broad implications for precision medicine, including identifying gene copy number variations in breast cancer and tracking the dynamics of immune responses in tuberculosis infections [16][19]. Implications for Research and Development - The advancements in Stereo-seq V2 position it as a powerful tool for various fields, including infectious diseases, antibody drug development, and neuroscience, facilitating high-resolution spatial analysis of precious archived samples [25]. - The technology represents a significant leap from merely observing cells to understanding the intricate interactions within them, marking a new era in life sciences research [20][21].
