Current treatments, including topical lacrimostimulants and lacrimomimetics, primarily offer symptomatic relief without restoring lacrimal gland function. Mesenchymal stem cell (MSC) therapy, with its regenerative and immunomodulatory properties, has been investigated in preclinical and veterinary studies but remains critically underexplored for its clinical relevance in treating KCS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic review was conducted on April 24, 2024, using Medline, Embase, Web of Science, and CABI databases. Studies evaluating MSC therapy in dogs and cats with KCS were included. Data collected included demographic information, baseline and post\u2010treatment Schirmer tear test (STT) values, and ocular symptoms such as discharge, conjunctival hyperemia, and corneal changes. The risk of bias was assessed using validated tools, and the quality of evidence was graded using the Oxford Centre for Evidence\u2010Based Medicine (OCEBM). Statistical analyses were performed with STATA to compare STT values at baseline and after 1\u2010 and 6\u2010month follow\u2010ups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Six studies involving 151 eyes from 98 dogs were included. Studies demonstrated low to moderate risk of bias, and evidence quality was graded as level C. MSC therapy significantly increased tear production and improved ocular comfort, with mean STT increases of 0.68\u2009mm\/min at 1\u2009month and 1.51\u2009mm\/min at 6\u2009months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>MSC therapy offers statistically significant improvements in tear production in dogs with KCS and is considered a safe treatment option.
