induce a strong enough response. Mesenchymal stem/stromal cells (MSCs) have demonstrated potent and broad immunomodulatory and anti-inflammatory capacity (Abdi et al., 2008; Wada et al., 2013). Therefore, MSC-based therapy could potentially be an effective treatment for COVID-19. Notably, due to their regenerative properties (Mahla, 2016), MSCs can promote the repair of damaged ti
