In our integrated dataset, fgf24-expressing Müller glia were divided into two cell clusters based on the expression of the cell surface glycoprotein-encoding gene cd99, which is involved in leukocyte migration and endothelial cell adhesion (Schenkel et al., 2002; Tanaka, 2016), as well as inhibiting tumor growth through suppressing EGFR signaling (Lee K. J. et al., 2020). This evidence concerns the gene CD99 and neoplasm.
