Background: Indolent ulcers are noninfectious epithelial defects of the cornea, typically presenting as chronic, superficial lesions. These ulcers are most commonly observed in dogs and are the leading cause of ophthalmic consultation in the UVS Ophthalmology service. These ulcers, which are more common in older dogs, often have difficulty healing naturally. Underlying eye conditions and infections can further hinder the healing process, potentially causing vision impairment and eventually removal of the eye. In this manuscript, we present the success of using mesenchymal stem cells (MSC) in a preliminary pilot trial to treat indolent ulcers.
Methods: Companion animals with indolent eye ulcers that did not respond to traditional treatment protocols were treated with suspended canine bone marrow-derived MSCs (5 x 105 cells total) administered via an eyedropper and then monitored for a period of 2-3 hours post infusion before being released back to their owners. Dogs had a follow up visit after 48-72 hours by the veterinary team.
Results: Of the 12 adult canine pets with indolent ulcers, MSC treatment led to recovery of the ulcers within 5-6 weeks after administration.
Conclusions: This pilot trial showed the promise of the use of topical canine MSC for dogs with indolent ulcers. In the near future we are planning to conduct a randomized prospective trial. We consider the use of expanded stem cells to treat indolent ulcers represent a novel and potentially effective approach and it is our intention to further expand the use of MSCs in the indication of ocular indolent ulcers.
