Figure 9. Expression of keratocyte-specific markers in isolated cells from ReLEx (Refractive Lenticule Extraction) lenticules. Fresh (A) and cryopreserved (B) lenticues. Human keratocan (KERA) with 167 bp, aldehyde dehydrogenase 3A1 (ALDH3A1) with 495 bp and the housekeeping gene glyceraldehyde 3-phosphate dehydrogenase (GAPDH) with 498 bp. (+): Lenticule sample. (-): Negative control.
