Immunosuppression in corneal transplantation [PDF]

Eye, 1995
This paper reviews the clinical post-operative management of keratoplasty and the management of corneal graft rejection. In both instances corticosteroids remain the mainstay of treatment; however, the literature shows a wide range for both route and frequency of administration.

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Multiplex polymerase chain reaction for pathogen detection in donor/recipient corneal transplant tissue and donor storage solution

Scientific Reports, 2017
Corneal transplantation is a safe, reliable method of restoring visual acuity in patients with corneal disorders. Although it has a very high success rate, rejection can still occur, especially if the site is infected.

Bioprinted Organoids: An Innovative Engine in Biomedicine

Advanced Science, EarlyView.
Bioprinted organoids refer to either the printing of stem cells into tissue shape and subsequent differentiate into organoids, or assembling induced organoids as bioinks to replicate native organ. It enables the creation of miniaturized organs with complex architectures and physiological functions, potentially enhancing reproducibility, throughput, and
