Abstract

Transparency of the cornea is maintained by regulation of stromal hydration through the barrier and pump functions of thecorneal endothelium. Human corneal endothelial cells (CECs) normally have a limited proliferative capacity in vivo. Humancorneal endothelial cells gradually decrease with age throughout life and decline dramatically after endothelial damage dueto; surgical and non surgical trauma, and acute angle-closure glaucoma. Therefore, corneal endothelial deficiency resultsin irreversible corneal edema because of the relative lack of endothelial cell proliferative capacity. Over the last two decades,the surgical treatment has evolved from traditional penetrating keratoplasty to several new endothelial keratoplasties procedures to replace patient's dysfunctional human corneal endothelial cells with a healthy one that contains varying amountsof the posterior corneal stroma or no corneal stroma from a cadaveric donor. However, all of these keratoplasty proceduresrequire a donor cornea and the worldwide shortage of corneas limits its application. To overcome the problems of donorcornea shortage, the application of corneal endothelial cell sheet transplantation using cultured human corneal endothelialcells has been attempted in experimental studies. This review presents current knowledge on the tissue engineering of cornealendothelium using cultured human corneal endothelial cells.

Özet

Korneanın saydamlığı korneal endotelin stromal hidrasyonu düzenleyen bariyer ve pompa fonksiyonları aracılığıyla korunur. İnsan korneal endotel hücreleri in vivo olarak sınırlı çoğalma kapasitesine sahiptir. Yaşla birlikte insan korneal endotelhücre sayısı gittikçe azalır. Cerrahi - cerrahi dışı travma ve akut açı kapanması glokomundan sonra da endotel hasarınabağlı korneal endotel hücre sayısında dramatik düşüş görülür. Endotelyal hücrelerin çoğalma kapasitesinin yetersizliği nedeniyle kornea endotel yetmezliği geriye dönüşümsüz kornea ödemine neden olur. Cerrahi tedavi son 20 yılda geleneksel penetran keratoplastiden, hastanın işlevsel olmayan korneal endotel hücre tabakasının, sağlıklı donör kornea endotel tabakasıile yer değiştirildiği birçok yeni endotelyal keratoplasti prosedürüne dönüşmüştür. Ancak tüm keratoplasti prosedürleri birdonör kornea gerektirir ve dünya çapındaki donör kornea yetersizliği bu uygulamaları sınırlar. Donör kornea yetersizliğininüstesinden gelmek için kültüre korneal endotel hücreleri kullanılarak korneal endotel hücre tabakalarının transplantasyonudeneysel çalışmalarda uygulanmıştır. Bu derleme, kültüre korneal endotel hücreleri ile kornea endotel doku mühendisliğihakkında güncel bilgileri sunmaktadır.
