1. A method of identifying a cell or cell marker, comprisinga) isolating target cells by label-free imaging flow cytometry;
- b) quantifying gene expression in the target cells by single cell sequencing,wherein sequenced transcript reads are obtained from RNA sequencing of 20,000 or more single cells from a biological sample, wherein the sequencing depth is about 10,000 or less reads per cell;
c) clustering the target cells based on the gene expression by application of one or more algorithms;
d) determining a transcription signature for each cluster based at least in part on identifying differentially expressed genes between two or more clusters and between each cluster and the remaining cells as background by applying an unsupervised machine-learning model; and
e) validating gene expression against cellular morphology.

8. A method of determining transcription signatures for cell types or cell sub-types, comprising:
-
isolating a population of cells by label-free imaging flow cytometry; identifying cell types and/or cell sub-types by applying one or more clustering algorithms to a set of sequenced transcript reads from the population of cells, wherein the sequenced transcript reads are obtained from RNA sequencing of 20,000 or more single cells from a biological sample, wherein the sequencing depth is about 10,000 or less reads per cell, wherein each resulting cluster of sequenced transcript reads identifies a particular cell type or cell sub-type; and determining a transcription signature for each identified cell type or cell sub-type based at least in part on identifying differentially expressed transcripts between the identified cell type or cell sub-type by applying an unsupervised machine-learning model. - View Dependent Claims (9, 10, 11, 12)
