Abstract
|
|
|
|
Animal cells have been widely and continuously studied due to their usefulness in biological researches and production of pharmacological agents as well as food additives. Nevertheless, there are several problems such as the existence of viruses which introduce the possibility of mammalian-infection. In this reason, recently, animal cells derived from marine organisms have emerged to overcome these problems by many researches. However, marine animal-derived cells have not yet been well developed. The banded hound shark occupies an important position in an evolutionary perspective and currently a few biological substances have been used for medicines or food additives such as shark squalene and cartilage extract. In this study, primary cells were cultivated from a banded hound shark nose containing many extracellular matrix (ECM) materials. After successful isolation of one type of primary nasal cell, we optimized culture conditions including coating materials, media composition, serum concentrations and pH. Additionally, these cells demonstrated proliferation ability in vitro, generating secretions of collagen and sulfated polysaccharides. The cultivated primary cells are useful in the study of cellular biology and may be used to create a variety of ECM-originated bioactive substances.
