Differential expression genes(downstream analysis)

Question

[odi]

I have generated a list of differentially expressed (DE) genes following bulk RNA-seq analysis. I am interested in classifying these genes according to their association with specific stem cell developmental stages, namely 2i, epiblast, and post-epiblast. Could you advise me on how to go about this classification? Is there a specific database or resource that I can utilize to determine which developmental stage these genes are associated with? Gene set enrichament analysis or is single cell the only way? Thank you for your assistance!

I believe you should go to gene co-expression analysis
