Production of small-scale laboratory-grown cell-based fish meat from Asian seabass muscle and fin cell lines.

Abstract

Aquaculture is essential to satisfying the world's increasing demand for seafood. Likewise, overfishing is becoming more common across the world, inflicting tremendous damage to the marine environment. There is a critical need for protecting sustainable fishing resources to fulfil the increasing demand for seafood. The current work focuses on the cells derived from Asian seabass muscle (SBM) and Asian seabass fin (SBF) for producing cell-based fish meat. SBM and SBF cells were seeded separately in the TubeSpin bioreactor and placed on a 3D orbital rocker. Cell sheets formed on the TubeSpin were detached and formed spheroid-like structures. These structures aggregated and formed visible tissue-like structures on 45 d of culture. Immunotyping results revealed that the presence of myosin in the cells of muscle and fin tissue, and indicating that these cells might have originated from myoblasts. The origin of cultured tissue from SBM and SBF cell lines was confirmed by amplification and sequencing of the L. calcarifer specific mitochondrial larger subunit rRNA gene. Additionally, these cells could be cultivated in multilayered forms that were appropriate for large-scale production. This approach provides a new method for the production of cell-based, laboratory-grown meat from the Asian seabass muscle and fin cell lines.
