Abstract (original English)
Anosmia, a serious condition that affects the sense of smell, has no universally agreed-upon treatment. Adult stem cells are considered a potential option for treating anosmia. This study aims to evaluate the efficacy of mesenchymal stem cells derived from different tissues in an anosmic mouse model induced by 3-methylindole (3-MI). In our study, 36 mice with 3-MI-induced anosmia were divided into subgroups. Anosmia was confirmed by performing a food-finding test (FFT) in each group. Intranasal phosphate-buffered saline was administered to the first group, adipose tissue-derived mesenchymal stem cells (ADSCs) to the second group, and bone marrow-derived mesenchymal stem cells (BMSCs) to the third group. Stem cells were obtained from green fluorescent protein (GFP)-transgenic mice. Olfactory function was evaluated weekly using the FFTs. Mice were sacrificed at the second and fourth weeks following 3-MI injection and examined histopathologically. Compared to the control group, stem cell-transplanted groups demonstrated significantly improved food-finding times measured at week 2 and week 4 FFTs following the 3-MI injection (respectively; p = 0.001, p = 0.008). Additionally, increased olfactory marker protein expression and olfactory epithelial thickness, along with reduced epithelial damage, were observed in the stem cell-transplanted groups compared to the control group (p < 0.0
