Fig. 4From: Donor age and long-term culture do not negatively influence the stem potential of limbal fibroblast-like stem cells a f-LSC two-dimensional electrophoresis master proteomic map with labeled proteins. Two-dimensional gel electrophoresis assay resulted in a master gel that revealed 164 spots, 78 % of which had an average pixel density of about 0.3. b Densitometry profile of f-LSC proteins. f-LSC fibroblast-like limbal stem cellBack to article page
