Invertebrate cell culture considerations: insects, ticks, shellfish, and worms

Area of Science:

• Invertebrate cell biology
• Cell line development
• Biotechnology

Background:

• Cell line establishment is routine for insects and arachnids but challenging for other invertebrates, particularly marine species.
• There is a significant need for cell lines from marine invertebrates crucial for aquaculture, parasite research, and biomedical applications.

Purpose of the Study:

• To anticipate challenges in establishing cell lines from refractory invertebrate taxa.
• To discuss potential solutions and strategies for successful invertebrate cell culture.
• To provide guidance on optimizing culture conditions and cell line characterization.

Main Methods:

• Reviewing experiences with molluscs and trematodes, and ongoing invertebrate cell culture research.
• Analyzing critical culture parameters: media, temperature, pH, additives, and sterile techniques.
• Exploring methods for feeding, tissue fragment retention, feeder layers, and inducing cell replication.

Main Results:

• Identified key variables and challenges in establishing invertebrate cell lines.
• Proposed strategies for sterile primary cultures and optimizing cell growth conditions.
• Highlighted advancements in cell line characterization and immortalization techniques.

Conclusions:

• Successful strategies exist for overcoming barriers in invertebrate cell line establishment.
• Recent successes and emerging technologies suggest a future where cell propagation in refractory species becomes routine.
• This work provides a roadmap for developing essential cell lines from diverse invertebrates.
