Sažetak

Limbal stem cells play a crucial role in maintaining the integrity of the corneal surface in a healthy condition or after injury through corneal renewal and repair. In pathologic conditions these cells could be replenished with cultivated allogenic limbal cells. In this investigation, limbal stem cells from small fragments of donor tissue were cultivated in vitro for treatment of corneal lesions in dogs. Fourteen dogs were divided into two groups of seven animals each: a group of dogs with corneal lesions treated using the classical veterinary ophthalmology approach, and a group of dogs with corneal lesions treated with the application of cultivated allogenic limbal cells. Regardless of the size and location of the corneal lesions, after 30 days in the group of dogs with corneal lesions treated with the application of cultivated allogenic limbal cells ophthalmological examination showed no signs of any eye disorder except corneal edema (14.29 %). In the group of dogs with corneal lesions cured using the classical veterinary ophthalmology approach, 30 days after the beginning of treatment ophthalmological examination showed 42.86 % mild/incisional blepharospasm, 85.71 % secretion, 100 % observable conjuctival congestion, 14.29 % eye liquor dimming, 85.71 % corneal edema and 85.71 % irritation. After application of cultivated allogenic limbal cells, corneal lesions were completely healed 15 days earlier than the lesions treated with conventional ophthalmological therapy. Allogenic limbal cells were capable of restoring corneal clarity with no development of ocular complications.
