Abstract

Despite extensive research spanning several decades, a commercial cell line for prawns remains elusive, and we have yet to determine the ideal conditions required for successful in vitro cell cultures of crustaceans. This study marks the first application of mass spectrometry to analyze lipid content changes in prawn culture media, allowing us to investigate how specific metabolites in media correlate with cell cycle and proliferation status. To investigate these relationships, short-term cell culture experiments were conducted using three commercial media: Dulbecco's modified eagle medium (DMEM) high glucose, Opti-Minimal essential media (Opti-MEM), and DMEM:F12. We monitored metabolic activity, performed cell-cycle analysis, and used mass spectrometry to analyze lipid metabolic profiles of culture media. This comprehensive approach enables us to examine the interplay between media lipidomic content and cellular behavior. Our results revealed that all three media sustained cellular metabolic activity. DMEM high glucose and Opti-MEM showed peaks in metabolic activity at day 4, while DMEM:F12 exhibited a peak at day 7. Opti-MEM supported the shortest doubling time, making it ideal for short-term culture. Interestingly, DMEM high glucose retained more attached cells on day 1 and had the highest count on day 4, with a noticeable trend towards the G2/M cell-cycle phase. Moreover, our lipidomic analysis of Opti-MEM revealed significantly higher concentrations of 26 annotated lipids compared to the other media. Notably, lipids like phosphatidylcholine and phosphatidylserine were consistently abundant in all three media, and palmitate levels correlated with proliferation phase. These findings have significant implications for establishing sustainable crustacean cell culture lines. Understanding the lipidomic compositions and their associations with cell-cycle dynamics and proliferation allows for precise conditioning of culture media to promote sustainable growth and delay cellular entry into quiescence phases. This knowledge contributes to the long-term goal of maintaining robust prawn cell cultures for various research and biotechnological applications.
