In this study, we showed that stemness markers (NANOG, OCT4, SOX2 and telomerase reverse transcriptase) and colony forming unit-fibroblast apparently decreased accompanied with incidence of senescence-associated β-galactosidase-positive cells by repeated passage. Additionally, we suggested that down-regulation of cell proliferation in senescent BM-MSC was related to increased expression of cyclin-dependent kinase inhibitor 2B (CDKN2B). On the other hand, forced expression of NANOG into senescent BM-MSC brought upregulation of several stemness markers and downregulation of CKDN2B accompanied with restoration of proliferation potential and osteogenic ability.

The presence of dermatitis in the subject individuals was recorded during blood sample collection. White blood cell and eosinophil counts, serum total IgE concentration, and serum allergen-specific IgE units (ARUs) were measured. White blood cell and eosinophil counts were significantly higher in horses with dermatitis in summer compared to winter. On the other hand, there was no significant difference in serum total IgE concentration regardless of the presence of dermatitis or the season. Horses with dermatitis in summer showed higher ARUs derived from red ants, horseflies, biting midges, cockroaches, deerflies, and mosquitoes than those in winter. These ARUs were positively correlated with white blood cell and eosinophil counts.
