Solution Overview

Problem

Current methods for isolating and culturing primary cells from aquatic animal tissues are hindered by the use of chemical reagents or enzymes, leading to short cell lifespan, inconsistency, high costs, and limited production volume, as well as ethical concerns related to animal welfare, particularly for aquatic invertebrates which are sensitive to these reagents.

Innovation Solution

A method involving physical sectioning of aquatic animal tissues without chemical reagents or enzymes, followed by centrifugation and culture with a cell culture medium containing complex antibiotics such as penicillin/streptomycin, amphotericin B, gentamycin, kanamycin, ampicillin, and tetracyclin, to isolate and culture primary cells effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If chemical reagents or enzymes are used for tissue sectioning, then cell isolation efficiency is improved, but cell lifespan decreases and animal welfare issues arise

Engineering Contradiction:
