Abstract

Study Design: Experimental animal study. Purpose: This study investigated the therapeutic effects of human breast milk stem cell (BMSC)-conditioned medium (BMSC-CM) in a model of spinal cord injury (SCI) in male Sprague-Dawley rats. Overview of Literature: SCI is one of the leading causes of disability in addition to sensory and motor impairment. So far, there have been no successful treatments for SCI. Given the positive outcomes associated with using stem cells and their derivatives as a treatment for various diseases, there is a growing interest in using them as an SCI treatment. Recent research has demonstrated that CM from stem cells has therapeutic advantages.
Methods
Human BMSCs were isolated and characterized, and CM was subsequently collected. Animals received an intrathecal administration of BMSC-CM after SCI. The activity of caspase-3 was measured to assess apoptosis, and levels of tumor necrosis factor-α and interleukin-1β were measured to assess inflammation. Also, sensory and locomotor performances were assessed after SCI and BMSC-CM administration.
Results
Administration of CM from BMSC reduced apoptosis and inflammation at the site of injury in a rat model of SCI (p<0.05). Motor, sensory, locomotor, and sensorimotor performances were significantly improved in rats that received BMSC-CM after SCI.
Conclusions
Intrathecal administration of BMSC-CM improved recovery in a rat model of SCI.
