Aebp2 is intracellular. Therefore, intracellular staining would be required to identify Aebp2-positive cells; for instance, prior to scRNA-seq. However intracellular staining creates pores in the cell membrane that can result in loss of transcripts and inaccurate gene expression measurements.
Identifying cell surface markers associated with Aebp2 could provide a proxy to circumvent that technical difficulty.
