Table 1.

Site-specific expression of stem/progenitor and corneal endothelial differentiation markers.

Posterior Limbus Regions	Marker Expression
Peripheral endothelium (PE)	Lgr5, Prdx6, nestin (sporadic), CD34 (scarce), TERT (sporadic), ZO1, Na⁺K⁺ATPase
Transition zone (TZ) Entire TZ	Vimentin, HNK1, Pitx2, p75^NTR
Inner TZ	Lgr5, Prdx6, CD34, TERT, nestin
Outer TZ	CD44
Trabecular meshwork (TM)	Vimentin, CD44

Note: cells immunopositive to Lgr5, TERT, CD34, Pitx2 were detected in posterior stromal region close to the inner TZ surface.
