The HB-adMSC group showed reduced TNF-α and interleukin-10, along with elevated interleukin-6 and CRP, consistent with excessive COVID-19-like immune response that involves elevations in proinflammatory cytokines such as TNF-α, interleukin-6, interleukin-10, and interferon-γ (22–25). Here, CRP is linked to COVID-19.
