发表在 Nat Methods. 2015 May;的文章，至今（2019-10-14）引用已经近1000啦，提出了一个非负矩阵分解的算法CIBERSORT根据LM22来计算不同类型细胞的比例。
CIBERSORT should enable large-scale analysis of RNA mixtures for cellular biomarkers and therapeutic targets (http://cibersort.stanford.edu/).
数据在Supplementary Table 1
Leukocyte signature matrix (LM22). Details of LM22, including gene expression matrix and source data.
关于LM22
文章是这样描述的：It contains 547 genes that distinguish 22 human hematopoietic cell phenotypes, including seven T cell types, naïve and memory B cells, plasma cells, NK cells, and myeloid subsets (Supplementary Table 1, Supplementary Fig. 2, and Online Methods).

CIBERSORT同时提供R包和在线网页工具，可以对用户的表达矩阵进行非负矩阵分解后计算不同细胞类型的比例。（后面我们会出一系列教程）
这是一个很火爆的数据挖掘方向
我安排我们生信菜鸟团数据挖掘团队成员帮忙收集整理了全部使用CIBERSORT在bulk癌症转录组数据看LM22免疫细胞比例的文章，详细列表如下：
