Abstract

A cytokine storm suppressor containing microparticles derived from a culture supernatant of dental pulp-derived stem cells, adipose-derived stem cells, bone marrow-derived stem cells, umbilical cord-derived stem cells or immortalized stem cells thereof wherein the microparticles contain extracellular superoxide dismutase (SOD3) in an effective amount capable of repairing a tissue or a cell damaged by a cytokine storm or a higher amount and which is used for administration to a human or nonhuman animal with a cytokine storm before damage of a tissue is caused by the cytokine storm to suppress the tissue damage by the cytokine storm through suppression of the cytokine storm or used for administration to a human or a nonhuman animal with damage of a tissue caused by a cytokine storm to repair the tissue damaged by the cytokine storm through suppression of the cytokine storm; method for using the cytokine storm suppressor; a screening method.
