cell-type identification using marker gene expression could lead to difficulties in distinguishing alternations in the cell-type specification from changes in gene regulation. Identifying cell types using information
生物学重复的不同条件下的scrna-seq数据的差异基因表达分析 (https://www.10xgenomics.com/resources/analysis-guides/differential-gene-expression-analysis-in-scrna-seq-data-between-conditions-with-biological-replicates) 需要注意的是,这部分差异表达分析不应与下一部分,计算来自两个簇的细胞之间的差异表达基因以...

一张图总结一下CellMarker 2.0数据库概况:👇 3CellMarker 2.0 更新亮点 本次更新的亮点如下:👇 新增36300个tissue-cell type-marker条目、474个组织、1901个细胞类型和4566个marker; 新增48种测序技术分类的细胞marker,包括10×Chromium、Smart-seq2和Drop-seq等; 新增29种细胞Marker,包括蛋白编码基因,lncRNA和p...
Potential doublets were scrutinized using Scrublet from the scran package (1.14.6)66, and marker gene expression was used to assess whether a hybrid transcriptome could mimic the cell type in focus; these analyses did not lead to further removal of cell-associated barcodes. Clustering...
Conversely, the expression of cell-cycle genes is low in INT cells and therefore they are the quiescent interommatidial cells. Interestingly, we did not find a distinct cell population corresponding to cone cells but their respective marker cut was detected throughout the LPR population. This is...
Since Helios expression is associated with T cell activation and cellular division, regardless of the cell subset involved, it does not appear suitable as a marker to distinguish natural and induced Treg cells. 展开 关键词: Animals Humans Mice T-Lymphocytes Cells, Cultured Transcription Factors DNA...
最后,我们调用cellassign()函数进行细胞类型注释,使用基因表达矩阵、marker基因和size factors作为输入。 fit <- cellassign(exprs_obj = example_sce[rownames(example_marker_mat),], marker_gene_info = example_marker_mat, s = s, learning_rate = 1e-2, ...
Define the expression 细胞类型定义的第一个也是最重要的说明是其表达的marker基因。Garnett提供了几种用于指定marker基因的选项,详细信息如下。 image 以上是为细胞类型指定marker基因的默认方法。使用此规范时,Garnett会计算每个细胞的marker基因的得分,并考虑到总体的表达水平和测序深度。
3. The cell type labels are based on marker expression patterns shown in Additional file 1: Figures S2–9. b Principal component analysis of the z-scored matrix of average chromosomal expression for each tumor showing a characteristic axis of variation, which we call the “malignancy score”, ...
