Data for comparison between control and treat samples (cells or patients) by single-cell RNA-Seq

Question

[landscape95]

Hello everyone, I am trying to compare the outcome (survival time, etc.) between the treated and control group of cancer cells or patients (it could be breast cancer or any other types of cancer) by single-cell RNA-Seq to investigate the advance of scRNA-seq instead of RNA-Seq. However, as I searched, most of the studies on single cell now just focus on one direction, such as observing and analyzing the cellular characteristic after all treat or all control patients/cell.

Does anyone have some idea on studies which we may get control and treated group of cells or patients based on scRNA-seq? Thank you very much!
