Abstract (original English)

There is little research concerning the role of stem cells in necrotizing enterocolitis (NEC). Bone marrow-derived mesenchymal stem cells (BMDSC) and amniotic fluid-derived stem cells significantly reduced the amount and severity of NEC in the animal models. ADSCs share similar surface markers and differentiation potential with BMDSCs. Their potential role in the setting of NEC has not been researched before. The hypothesis of the study was that prophylactic intraperitoneal administration of ADSCs before the onset of the disease will result in limiting the inflammatory response, effecting a lower incidence of NEC. On a molecular level, this should result in lowering the levels of inflammatory cytokines IL-1 and IL-6. The local ethical committee for animal experiments approval was acquired (WAW2/093/2021). We utilized a self-modified rat NEC model based on single exposure to hypothermia, hypoxia, and formula feeding. One hundred and twenty-eight rat puppies were divided into two groups-prophylaxis (ADSC-NEC, n = 66) and control group (NEC-PLCB, n = 62)-to measure the influence of ADSCs administration on the inflammatory changes in NEC, the level of cell engraftment, and the histopathology of the disease. The analysis did not show a significant effect on histopathology between groups, H(2) = 2.12; p = 0.347; η²H = 0.00. The intensity of the NEC variable results was similar across
