scRNAseq: How to select your reference dataset for cell type identification

Question

[Solal]

HI guys, Sorry that's gonna be a pretty naive question, I am trying to the cell types coming from my sample (Mice Hippocampus) and am kind of lost as to what reference dataset I should use. I've created my tSNE plot using Seurat but I don't know how to proceed to identify my clusters.

Cheers and thanks.
