Cell culture and cell lines have assumed an important role in studying physiological, pathophysiological, and differentiation processes of specific cells. It allows the examination of stepwise alterations in the structure, biology, and genetic makeup of the cell under controlled environments.
With the deepening of economic globalization, people’s demand for aquatic products is gradually increasing. Aquaculture practitioners began to pursue high yield and high income, but the emergence of this large-scale and high-density farming technology will inevitably accelerate the transmission and spread of diseases in water. In order to better this problem, cellular models are needed for studying fish growth, disease, reproduction, genetics, and biotechnology.
A cell line, in simple terms, refers to a defined population of cells capable of proliferating indefinitely in vitro. The path toward developing a cell line starts with the development of primary cell culture, which is derived from a specific tissue of the donor animal. Many factors come into consideration while choosing the donor animal such as age, health condition, etc. The type of tissue chosen depends on the application intended for the developed cell line. For example, hemocyte culture can be used for applications in immunology. Other critical factors are the inherent ability of the cells to proliferate (hemocytes and heart cells have limited capacity for proliferation whereas stem cells and germ cells have good proliferation capacity), and lesser chances of contamination by bacteria, fungi, etc. in the primary cell culture (gills being in continuous contact with the external environment have more chances to harbour bacteria and fungi, whereas internal organs tend to more aseptic in nature).
The cell culture medium in which cells are cultured should be able to provide all the necessary factors required by the cells to survive, proliferate, and carry out metabolic activities. Therefore, the development/optimization of organism/tissue-specific cell culture medium is itself a research area of importance. The cell culture conditions provided in vitro such as pH, temperature, etc. should be as close as possible to the physiological conditions.
Certain cell culture systems undergo spontaneous immortalization in vitro leading to the development of a continuous/immortal cell line. Carcinogenic primary cell cultures also often develop into continuous cell lines. Immortalization can also be induced in cell culture systems by way of transfecting the cells with viral oncogenes or by developing hybrid cells (fusion of primary cells with those from a continuous cell line).
Aquatic animal health and disease management are now studied from a variety of angles, such as environmental protection and pollution control, human health and epidemiology, site selection and culture technologies, monitoring and sanitation of aquaculture facilities, diagnosis and treatment of diseases of cultured species, avoidance of nutritional diseases, prevention of epidemics of mortality in culture facilities, formulation and implementation of regulatory measures, and more. Aquatic farm animals, in contrast to terrestrial farm animals, require greater care to monitor their health because they live in a complex and dynamic habitat and are not easily visible except under tank holding settings.
Aquatic animal health management is one of the core research themes of the centre. The research team focusing on bacterial, viral, fungal and protozoan and metazoan parasitic diseases of finfish and shellfishes and it’s epidemiology, pathology, host-pathogen interaction, immunology, development of management measures for the control of diseases such as vaccine development, probiotics, bioremediation, prophylactic measures etc. the team working on the development of novel diagnostic tools for the detection and identification of pathogens.
