Twenty-four horses with lameness localized to the metacarpo-\/metatarsophalangeal joint or a single joint of the carpus were enrolled in this study. We evaluated the response of intra-articular injection with 10 million activated (aMSC) or non-activated (naMSC) allogeneic equine umbilical cord blood-derived mesenchymal stromal cells (MSCs). Subjective and objective lameness was assessed on Days 0, 1, 21, and 42. The treatment injection was randomly assigned and performed following the baseline assessment on Day 0. naMSC-treated horses had straight-line lameness scores that were significantly lower on Day 21 (1.0 \u00b1 1.15) and Day 42 (1.13 \u00b1 1.00) than on Day 0 (p = 0.0098 and p = 0.0418, respectively). aMSC-treated horses had straight-line lameness scores that were significantly lower on Day 21 (0.96 \u00b1 1.03) and Day 42 (0.79 \u00b1 1.05) than on Day 0 (p = 0.0011 and p &lt; 0.0001, respectively). There was no significant difference between the treatment groups for any parameter at any timepoint. In conclusion, both aMSC and naMSC allogeneic MSCs resulted in significantly improved subjective lameness scores in horses when compared to baseline lameness scores.<\/jats:p>","DOI":"10.3390\/ani14233406","type":"journal-article","created":{"date-parts":[[2024,11,26]],"date-time":"2024-11-26T04:02:18Z","timestamp":1732593738000},"page":"3406","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Pilot Study to Assess the Safety and Efficacy of Umbilical Cord Blood-Derived Mesenchymal Stromal Cells for the Treatment of Synovitis in Horses"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3088-8827","authenticated-orcid":false,"given":"Kathryn","family":"Seabaugh","sequence":"first","affiliation":[{"name":"Orthopaedic Research Center, Translational Medicine Institute, Colorado State University, Fort Collins, CO 80523, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9234-0082","authenticated-orcid":false,"given":"Sangeeta","family":"Rao","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO 80523, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4872-9231","authenticated-orcid":false,"given":"Judith B.","family":"Koenig","sequence":"additional","affiliation":[{"name":"Department of Clinical Studies, Ontario Veterinary College, University of Guelph, Guelph, ON N1G2W1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4990-5006","authenticated-orcid":false,"given":"Lynn","family":"Pezzanite","sequence":"additional","affiliation":[{"name":"Orthopaedic Research Center, Translational Medicine Institute, Colorado State University, Fort Collins, CO 80523, USA"},{"name":"Department of Clinical Sciences, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO 80523, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven","family":"Dow","sequence":"additional","affiliation":[{"name":"Orthopaedic Research Center, Translational Medicine Institute, Colorado State University, Fort Collins, CO 80523, USA"},{"name":"Department of Clinical Sciences, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, CO 80523, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas G.","family":"Koch","sequence":"additional","affiliation":[{"name":"eQcell Inc., University of Guelph, 50 Stone Road East, Guelph, ON N1G 2W1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keith A.","family":"Russell","sequence":"additional","affiliation":[{"name":"eQcell Inc., University of Guelph, 50 Stone Road East, Guelph, ON N1G 2W1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sahar","family":"Mehrpouyan","sequence":"additional","affiliation":[{"name":"eQcell Inc., University of Guelph, 50 Stone Road East, Guelph, ON N1G 2W1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
