Other studies have found that human umbilical cord‐derived mesenchymal stem cells (hUC‐MSCs) have immunomodulatory and regenerative potential, and hUC‐MSCs ameliorate lung injury in ARDS and regulate YAP to facilitate AECs II differentiation into AECs I by decreasing pro‐SPC expression while increasing podoplanin (T1α) expression.65 Here, PDPN is linked to acute respiratory distress syndrome.
