前面一直介绍的胃癌单细胞数据集GSE163558,是10个样品的10x技术的单细胞转录组,可以分成6组,并不适合做相关性探索。首先是组别太多了,其次每个组就单个或者两三个样品。 这个是时候我们可以拿2022的这个胃癌单细胞文献做案例,标题是:《Parallel single-cell and bulk transcriptome analyses reveal key features of the gastric tumor microenvironment》,它的实验设计是 48 samples from tumors and matched normal tissue of 24 treatment-naïve patients were sequenced using 10X single-cell RNA-seq platform and then analyzed. 也就是说,这个GSE206785也是胃癌单细胞数据集,但是就两个分组,每个组是24个样品,首先同样的同时量化不同样品的不同单细胞亚群的相关性,如下所示的代码: rm(list=ls()) options(stringsAsFactors = F ) library (Seurat) library (ggplot2) library (clustree) library (cowplot) library (dplyr) library (stringr) library (ggs
