Spatial-in-Spatial: The Utility of Combining Fluorescence-Guided Multiple Sampling with Spatial-Omics in Human Glioblastoma.
Human glioblastoma (GBM) is a remarkable example of a highly aggressive and untreatable tumor. A formidable challenge in treating GBM is its extensive intratumor heterogeneity, which traditional bulk tissue analysis fails to capture. Fluorescence-guided multiple sampling, utilizing 5-aminolevulinic acid for tumor visualization, offers objective tumor tissue identification and enhanced spatial resolution. In this study, we present a perspective on a novel "spatial-in-spatial" approach that enables comprehensive analysis of tumor areas and their microenvironment-at macroscopic and microscopic levels-by combining fluorescence-guided multiple sampling with spatial-omics technologies. This perspective discusses how this integrated methodology has the potential to advance our understanding of GBM biology through the high-resolution, multidimensional characterization of tumor heterogeneity and identification of novel, area-specific therapeutic targets.
期刊介绍：
Molecular Cancer Research publishes articles describing novel basic cancer research discoveries of broad interest to the field. Studies must be of demonstrated significance, and the journal prioritizes analyses performed at the molecular and cellular level that reveal novel mechanistic insight into pathways and processes linked to cancer risk, development, and/or progression. Areas of emphasis include all cancer-associated pathways (including cell-cycle regulation; cell death; chromatin regulation; DNA damage and repair; gene and RNA regulation; genomics; oncogenes and tumor suppressors; signal transduction; and tumor microenvironment), in addition to studies describing new molecular mechanisms and interactions that support cancer phenotypes. For full consideration, primary research submissions must provide significant novel insight into existing pathway functions or address new hypotheses associated with cancer-relevant biologic questions.
