Figure 6. Analysis of reverse transcriptase polymerase chain reactions (RT–PCR) of limbal stromal cells. A: Expression of SSEA-4 transcripts by limbal stromal (LS) cells as compared to human embryonic stem cells, BG01V. B: Expression of various transcripts by limbal stromal cells such as ABCG2, p63, Pax 6, AE5, and keratocan sulfate was compared
to corneal stromal (CS) and corneal epithelial (CE) cells. GAPDH was served as housekeeping gene.
