Acta Neuropathologica: Spatial enrichment of glioblastoma cell state.

The authors determine whether the cell state may correspond to the terrain location within the tumorThe gene expression spectrum of cell state and proliferation was extracted from the study and applied to the databaseThe study found that these newly defined cell states did enrich in specific anatomical locationsThe project analyzed five anatomical areas: the leading edge () is an extremely rare glioma cell at the outermost boundary of the tumor; the intermediate region between the immersion tumor () and the core contains % of the tumor cells; the cell tumor () core has almost no non-tumor cells; the pseudopale cell () neuroglioma cells around necrosis gather around the necrosis region; and microvascular hyperplasia ()The authors used the analysis to compare the expression of the "cell state" gene determined by five anatomical locationsImportantly, a group of eight commonly used genes () did not show a significant association with any characteristicsIn addition (a non-malignant feature of a tumor composed of blood vessels) the cell status markers are positive for and proliferative characteristics but are neutral or negatively correlated with these four malignant characteristicsIn contrast, malignant cell state characteristic genes predict one or more anatomical regionsand together form the main intrusive interface or boundary between the tumor and the normal brainEnriches the characteristics of nerve () and protrusion glial progenitor cells () and astrocyte differentiation ()In contrast, the proliferative characteristics of this feature are neutral or very weak, indicating that these tumor areas contain fewer circulating cellsFinally, taking into account the reduction of cells in the region, we cannot exclude the potential contribution of non-tumor microenvironment elements to the correlation of these characteristicsIs the main anatomical feature contains an oxygen-deprived-dependent signal, and a negative signal indicates that the proliferation around necrosis is slowerIn contrast, the strongly enhanced proliferation signal in the core represents a rapidly divided gliomaIn addition, this function shows strong and negative signatures that highlight the specificity of gene signatures to the hypoxia regions of tumorsRESULTS: Use to determine which characteristic gene is most likely to predict cell state and anatomical locationBy setting eight thresholds in ten possible comparisons between five anatomical features, it is important to identify highly predictable genes The analysis determines the best predictors for the state of and, respectively Testing these genes as potentially reported genes for specific cell states and addresses may prove to be a powerful new tool for studying cell plasticity in preclinical studies Original link: - Original Source: Original Content Presentation EndStojudged Whether login ends.
