Establishment of shrimp cell lines: perception and orientation

Area of Science:

• Aquaculture
• Invertebrate Cell Culture
• Virology

Background:

• Continuous shrimp cell lines are crucial for investigating shrimp viruses impacting the multi-billion dollar aquaculture industry.
• Despite advances in cell line development for other species, no shrimp cell lines exist due to inherent cellular resistance to transformation.
• Over 25 years of research has failed to establish stable shrimp cell lines, hindering viral disease research.

Purpose of the Study:

• To review the current status of shrimp cell line development.
• To discuss the challenges and potential strategies for creating continuous shrimp cell lines.
• To outline future directions for shrimp cell line research.

Main Methods:

• Review of existing literature on invertebrate cell culture and shrimp virology.
• Analysis of molecular biology and gene transfer technologies for cell immortalization.
• Discussion of oncogenic induction and modified media approaches.

Main Results:

• No continuous shrimp cell lines have been successfully developed to date.
• Shrimp cells appear to inhibit spontaneous neoplastic transformations.
• Modified media improve cell growth but do not induce immortalization.

Conclusions:

• Development of exclusive shrimp cell culture media and appropriate transformation methods are critical.
• Oncogenic induction and gene transfer technologies offer potential pathways for future shrimp cell line development.
• Successful cell line development is essential for advancing shrimp disease research and aquaculture sustainability.
