This response exacerbates neural damage in the injured area by facilitating the infiltration of inflammatory cells and the release of cytokines, thereby remarkably impeding neural repair and functional recovery. Spermatogonial stem cells (SSCs) have the potential for spinal cord nerve regeneration. Concurrently, olfactory ensheathing cells (OECs), a unique cell type with neurorepair potential, can effectively enhance nerve regeneration through the secretion of various neurotrophic factors, the suppression of inflammatory responses, and improvements in the injury microenvironment. However, research concerning OEC induction systems and the differentiation of SSCs into spinal cord neurons remains limited.

Initially, primary SSCs were cultured and characterized through immunofluorescence, and the molecular mechanisms underlying the induction system were examined via western blot and quantitative reverse transcription (qRT-PCR) methods. An inflammatory environment was subsequently developed in a lipopolysaccharide (LPS)-activated microglial model to evaluate the impact of the induction system on SSC differentiation.

In addition, compared with those in the other experimental groups, the induced neuronal-like cells exhibited genuine neuronal characteristics. Importantly, JAK2/STAT3 pathway signaling plays a crucial role in this intricate cellular transformation. Suppression of the JAK2/STAT3 signaling pathway significantly improved differentiation efficiency and facilitated neural repair.
