Mesenchymal stem cell (MSC) implantation holds promise, with studies indicating their efficacy through the secretome. This study aims to assess the secretome\u2019s potency in regenerating peripheral nerve defects.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Animals and methods<\/jats:title>\n<jats:p>Twenty-eight spraque dawley (SD) rats were divided into four groups, with a 10mm segmental sciatic nerve defect created. Group I received autografts, while Groups II, III, and IV had proximal and distal nerve stumps fixed with a conduit. Group II received MSC implantation, Group III received umbilical cord MSC secretome, and Group IV was treated with silicone conduits. Motoric recovery was assessed using the Sciatic Functional Index (SFI) at 6, 9, and 12 weeks. After 12 weeks, rats were sacrificed for measurements of gastrocnemius muscle weight ratio and sciatic nerve histomorphometry.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Result<\/jats:title>\n<jats:p>The highest ratio of the gastrocnemius muscle were found in groups 1 and 3, namely 0.7 \u00b1 0.06 and 0.7 \u00b1 0.2 (p &lt;0.001). The highest number of myelinated axons was found in group 1 and 3, namely 175.1 \u00b1 15.9 and 168.9 \u00b1 11.7 (p &lt;0.001).
