What is the only tissue that can be transplanted from one person to another with little or no rejection in the retna of the eye?

The only tissue that can be transplanted from one person to another with minimal rejection in the retina of the eye is the retinal pigment epithelium (RPE). This is primarily due to the immune privilege of the eye, which reduces the likelihood of rejection compared to other tissues. The RPE plays a critical role in supporting photoreceptors, making it a valuable target for transplantation in retinal diseases.
