在兔接受单侧8 mm直径板层角膜移植术后，研究了供体角膜上皮的存活情况。术后3周、6周和12周，将从直径为5 mm的中央按钮、相邻0.75 mm宽的供体环、直径为10 - 13 mm的外周环和直径为5 mm的中央宿主按钮生长的培养的角膜上皮用于性染色质分析。结果表明，部分供体角膜上皮可存活至术后12周。然而，即使没有明显的上皮排斥反应，供体角膜上皮也会随着时间的推移而减少，同时宿主角膜上皮也会受到侵袭。
The survival of donor corneal epithelium was investigated in rabbits after they received unilateral 8 mm diameter lamellar keratoplasties with living donor tissue of a different sex from the host. Three weeks, 6 weeks, and 12 weeks postoperatively, cultured corneal epithelia, grown from 5 mm diameter central buttons, the adjacent 0.75 mm wide donor rings, the peripheral 10 to 13 mm diameter rings, and 5 mm diameter central host buttons were used for sex-chromatin analysis. The results indicated that some of the donor corneal epithelium survived up to 12 weeks postoperatively. Even in the absence of overt epithelial rejection, however, a time-dependent decrease of donor corneal epithelium and simultaneous invasion of host corneal epithelium were demonstrated.
