identifying contribution of specific cell subpopulation from mixture,with RNA-Seq data

Question

[Qingyang Xiao]

If the mRNA- Seq data is acuquired from a mixture of cells, such as whole blood cells, can I use some bioinformatics methods to distinguish the contribution of each cell subpopulation? Are there some databases provide with reference cell population expression profile, and corresponding packages?

Not unless the RNA was tagged at the cellular level during library prep (e.g. drop-seq, 10x single cell etc.)
