NR4A3 and laryngotracheoesophageal cleft: S1B) revealed three populations of mLCs: resident mLCs (Cd207, Epcam, and Mfge8), cycling mLCs (Top2a and Mki67, which also retained weakened expression of the resident mLC signature), and cells that appeared to be poised for migration out of the epidermis, which we have termed migrating mLCs (Cd83, Nr4a3, and Ccr7) to reflect a similar term used for these cells in human LC datasets (38–40).
