Umbilical Cord-derived Mesenchymal Stem Cells with Surfactant Protein B Alleviates Inflammatory Response in Acute Respiratory Distress Syndrome by Regulating Macrophage Polarization.

The findings showed that isolated UC-MSCs possessed multilineage differentiation potential. Additionally, UC-MSCs and UC-MSCs-SP-B inhibited the inflammatory response by promoting M2-like polarization, as well as reduced Th17 differentiation and promoted Treg differentiation.

Researchers used a Countstar instrument to assess cell numbers in the study's cell samples during quality assessment in the 2022 Balkan medical journal study.
