However, we found a robust increase in ZO-1 expression in mice exposed to NEC and treated with both hBM-MSCs concentrations, reaching levels similar to those observed in control pups (Control vs. NEC + PBS, p = 0.032; NEC + PBS vs. NEC + hBM-MSCs (0.5 × 106), p = 0.017; NEC + PBS vs. NEC + hBM-MSCs (1 × 106), p = 0.032) (Figure 5E). The gene discussed is TJP1; the disease is necrotizing enterocolitis.
