How are fish cells developed for cell-based aquaculture?

March 24, 2026

The process begins with the establishment of new cell lines from tissue explants.

From these small tissue fragments, cells proliferate and form stable cultures in the laboratory.

The next step is to understand the differentiation potential of these cells.

Através da coloração Oil Red O, é possível observar a diferenciação em adipócitos, as células responsáveis pela formação de gordura – um componente fundamental para o sabor, textura e qualidade nutricional do peixe.

Another important step is analysing differentiation into muscle cells. Using phalloidin staining, actin filaments characteristic of myocytes can be visualized, confirming the formation of muscle tissue.

The combination of muscle and fat cells is essential for developing relevant cellular models for the future of cellular aquaculture.

Each step in the lab brings biotechnology closer to new ways of producing seafood in a more sustainable and innovative way.

Circularity in cellular agriculture

At GreenCoLab, we turn a challenge into an opportunity.
The effluent from fish cell culture, which is still rich in nutrients, can be given a new lease of life instead of being discarded; it is being used to cultivate microalgae.
