Special Issue Information

Dear Colleagues,

For this Special Issue, we aim to gather scientific evidence related to the application and potential of regenerative medicine in the treatment of neurodegenerative diseases. Regenerative medicine is a multidisciplinary field based on the endogenous capacity of the living organism to self-repair and restore the functions of damaged tissues and organs. To facilitate and enhance this physiological regenerative process, different therapies and approaches are currently being studied in preclinical and clinical settings for the treatment of acute damage and chronic diseases. Stem cells play a pivotal role. Within the endogenous neural stem cell field, a homeostasis imbalance due to exogenous/endogenous toxic agents, the accumulation of reactive oxygen species (ROS), or impaired signaling pathways can cause neurotoxicity, contributing to chronic inflammation, which can lead to neurodegenerative pathologies and impede regeneration. Regenerative medicine strategies rely on the employment of stem cells, such as neural stem cells, mesenchymal stem cells (MSCs), induced pluripotent stem cells (iPSCs), or platelet-rich plasma (PRP), which use a systemic paracrine modality to produce a therapeutic response. Moreover, cell–cell contact may be also required. For example, MSCs can inhibit T-cell proliferation and dampen inflammation through direct contact between the transplanted MSCs and host immune cells. However, the numerous factors released by the healing cells may not only have an immunomodulatory function but also modulate the proliferation and differentiation of endogenous cells, as well as replacing the damaged cells themselves. A better understanding of the molecular mechanisms underlying the neurodegeneration process is necessary in order to improve the efficacy of regenerative medicine strategies.

Prion diseases are disorders caused by the misfolding of prion protein (PrPSc), leading to the accumulation of an abnormal form of the normal prion protein (PrP) found in the host. The secretome of mesenchymal stem cells (MSCs), including paracrine-soluble factors, holds promising potential to stimulate host regenerative capability and alleviate organ disorders. In this research, our goal was to investigate the neuroprotective properties of the secretome derived from adipose-derived mesenchymal stem cells (AdMSC secretome) in relation to the toxicity caused by PrP106−126 in SH-SY5Y cells. The findings showed that PrP106−126 treatment exacerbated the neurotoxicity of SH-SY5Y cells, as indicated by increased lactate dehydrogenase (LDH) release. However, the AdMSC secretome significantly decreased LDH release. Under PrP106−126 stimulation, the AdMSC secretome downregulated inflammatory markers (TNF-α and IL-1β) and upregulated anti-inflammatory IL-10. Treatment with the AdMSC secretome markedly reduced GFAP immunoreactivity in astrocytic C8D1A cells compared to treatment with PrP106−126 alone. In addition, the AdMSC secretome reduced Iba-1 immunoreactivity in BV2 cells activated by LPS. Western blot analysis showed that the AdMSC secretome inhibited pro-apoptotic factor Bax induced by PrP106−126 and increased the expression of anti-apoptotic factor Bcl-2. However, no significant difference was observed in the expression of caspase-3. The AdMSC secretome exhibited a considerable migratory effect on SH-SY5Y cells after 24 h, as demonstrated by the scratch assay. The results suggest that the AdMSC secretome can attenuate PrP106−126-induced neuronal damage. Full article
