WORLD WIDE FIRST [IP PROTECTED] PRODUCTION METHOD OF INVITRO GROWN CAVIAR- CELL BASED OOCYTES
In November 2020 we’ve initiated the MAGICCAVIAR Project as the world wide first cellular agriculture company to develop cell-based (ACIPENSERIDAE) Oocytes in vitro. We’ve finalized the appointment of our scientific advisory board comprised of world renowned Endocrinologists, Ichtyologists and Molecular Biologists holding positions as full appointed Professors at Berlins Humboldt University and at Wageningen University. Within the filing of “Means and Methods to produce cell based Caviar” and our produced Caviar Spheroids (prototypes) we’ve set the benchmark with its solid foundation on our years long tissuengineering expertise and patents in life sciences applications.
However, supporting literature suggests that the maturation of viable fish eggs ex vivo remains a challenging, but realistic objective, for the conservation and research community. Arguably a less technically ambitious aim in biological terms is to construct an ex vivo microenvironment that favours development of FGSCs into mature oocytes that can match the taste and mouthfeel of caviar. Our proprietary, 3D-printed, ex vivo fish ovary analogue also represents a valuable platform technology in the fields of aquaculture and conservation of biodiversity.
Fig. 1. - Production of functional eggs and sperm from in vitro-expanded ASGs by ASG transplantation. b Eggs produced by triploid female recipients that received expanded ASGs in culture (Cul-TP) or wild-type diploid female trout (2N cont). c Milt produced by wild-type diploid trout (2N cont), triploid trout (3N cont), male recipient trout that received in vitro-expanded ASGs (Cul-TP), or male recipient trout that received freshly prepared testicular cells (Non-cul-TP). Therefore, the method of in vitro expansion of ASGs established in this study is a breakthrough for these situations. Combination of in vitro expansion, cryopreservation, and transplantation of ASGs can be utilized to rescue fish species on the verge of extinction. *Takahashi et al. 2020
