Abstract

Objectives: This study compares the efficacy of stem cell transplantation in corneal regeneration and restoration of the limbic deficit in an experimental chemical burn in rabbits.


Methods: Biopsy was performed of the limbus and the chemical burns for all rabbits, and we collected the amniotic membranes from a pregnant female rabbit. We kept a control group without transplantation, to study spontaneous and natural healing, and we transplanted the stem cells produced in vitro under the corneal epithelium burned. To compare the result, we tested a group for amniotic stem cell transplantation, a group for limbal stem cell graft, and another group for combined transplantation of both types of stem cells.


Results: Transplanted rabbits develop permanent unilateral blindness due to a severe limbic deficit. The group receiving only amniotic stem cells shows temporary anatomical improvement without functional recovery. The two groups receiving limbal stem cells alone or combined with amniotic stem cells showed anatomical and functional satisfaction with quick recovery time for the combined transplantation.


Conclusions: A simple chemical burn can establish permanent blindness. When the limbic deficit is important, spontaneous healing is not available. Transplantation of stem cell transplant is the only way to repair this deficit and regenerate the cornea. Only limbic stem cells can be sufficient. Amniotic stem cells can support and speed up the healing time when it combined to limbal stem cells graft.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
