Abstract

BackgroundThe continuous accessibility of local animals for sustainable use is being eroded annually. Thus, a strategic vision for the conservation of biodiversity is of far-reaching emphasis to deal with unprecedented challenges in the local population extension facing in the future. This study aimed to establish and cryopreserve endangered Markhoz goat (Capra hircus) fibroblast cell lines in vitro.Methods and resultsThese primary fibroblast cells were isolated from 58 Iranian Markhoz goats and individually cultured by explant technique in DMEM medium supplemented with 10% FBS and 2 mM L-Glutamine, in the presence of Penicillin (200 U/ml)—Streptomycin (200 mg/ml) during the first passage number. The extracted cell lines were confirmed morphologically as fibroblast cells. The population doubling time for DMEM-cultured cells was 23 ± 0.5 h. Chromosomal analysis indicated a total chromosome number of 2n = 60 with > 95% frequency. The cultured cells were checked for bacteria, fungi, yeast, and mycoplasma contaminations and the results were reported negative. The efficiencies of the fluorescent protein encoded by VSV-G (pMDG) and lentiviral pCSGW vectors reported in a range of 65% value. According to the species identification analysis, the goat cell lines were banked and confirmed without any miss- and cross-contamination.ConclusionsThe significant issue in this paper can be concluded about the first report of the establishment of endangered Markhoz goat cell banking inside the country. This study demonstrated the successful establishment of a genetically stable fibroblast bank as a valuable genetic resource for the endangered Iranian Markhoz goat breed.

Highlights

Biodiversity conservation aims to manage the human use of natural resources to get the sustainable benefit of present and future generations
The essential aim of this research was the conservation of fibroblast cell lines derived from the ear margin tissues of Markhoz goat
The migrated cells included a combination of fibroblast-like cells and epithelial-like cells, because of using fibroblast culture mediums, a relative pure fibroblast line was observed after passages number three (Fig. 1a)
