It is important to secure various biological resources in situations of diminishing wildlife genetic diversity. Cultured cells are useful bioresources because they can stably store genetic information for a long time and can be expanded efficiently. Here, we established fibroblast cell lines from Apodemus agrarius as a new living resource. A. agrarius is an important sub-predator species in ecosystem food chains and for the study of infection epidemiology. Established cell lines were characterized by chromosome and mitochondrial gene analysis, the observation of cell morphology, and their anchorage-dependent growth pattern. We also examined susceptibility to endocrine disruptors (EDCs), which threaten biodiversity, using these established cell lines. Nonylphenol (NP) is a well-known EDC that threatens wildlife; however, its impact is poorly understood. Sensitivity to NP was confirmed based on two cell viability assays, namely MTT and lactate dehydrogenase. Cells exposed to NP were analyzed for abnormalities in cell growth and mitochondrial function by evaluating the expression of genes (specifically, those encoding growth hormone receptor and cytochrome C oxidase). This newly established cell line represents a valuable tool for the evaluation of toxic substances such as EDCs and this cell was biobanked for study about relationship between various environmental pollution and decreasing biodiversity.
