Open Cell Bank

Mission

We are working to democratize the fundamental building blocks of cultivated meat.

Cultivated meat researchers around the world share a fundamental need: access to relevant, well-studied, and fit-for-purpose cell lines. By making food-relevant cell lines and accompanying media formulations available for researchers across the field, we are working to:

  • Lower barriers to entry to allow new players to enter the field faster
  • Distribute shared tools to improve reproducibility and data sharing
  • Offer resources to reduce animal use in cell ag research and beyond
     

Initiating the TUCCA Open Cell Bank

As we continue to build the TUCCA Open Cell Bank, we will share current and upcoming resources here:

Suspension-adapted Immortalized Bovine Fibroblasts

SCiFi Foods, previously Artemys Foods, was a cultivated meat start-up focusing on the development of a hybrid plant-based/cultivated beef product. Through the use of CRISPR/Cas9 technologies to knock out p53 and insert Telomerase Reverse Transcriptase (TERT), they developed immortalized bovine cell lines, then adapted several of these cell lines for growth in single-cell suspension—a highly attractive phenotype for scale-up of cultivated meat.

When SCiFi Foods announced its closure and began the process of selling its intellectual property in 2024, The Good Food Institute (GFI) and Tufts collaborated to obtain these cell lines and their associated media formulations (GFI), and bank them for future distribution in the TUCCA Open Cell Bank (Tufts). 

We are now working to make these cell lines widely available. For researchers from academia and industry interested in accessing the cells, join the waitlist by completing this formShipments to academic researchers will begin first, with Tufts and GFI working to facilitate access to the cells by commercial entities at a later phase. Planned initial cell line offerings and media formulations can be found below:

  • TU-GFI-SCL1 is an immortalized suspension cell line developed by SCiFi Foods from domestic cattle (Bos taurus) connective tissue. TU-GFI-SCL1 was obtained by the Good Food Institute and deposited in the TUCCAf Open Cell Bank. TU-GFI-SCL1 was reported by SCiFi Foods to be their fastest growing cell line in serum-free media.

    Species: Bos taurus
    Common name: Domestic cattle
    Growth Properties: Suspension
    Cell type: Fibroblast
    Immortalization status (reported by SCiFi Foods): Immortalized; TERT, P53 knockout
    Comments (reported by SCiFi Foods): Antibiotic resistance markers still present (NeoR)
    Developer: SCiFi Foods
    Media: Media formulations for TU-GFI-SCL3 cells can be found open-sourced by GFI here.

    • FSF4 (minimal medium reported by SCiFi Foods, not yet validated at Tufts: formulation)
    • FSF6 (enriched medium reported by SCiFi Foods, not yet validated at Tufts: formulation)
    • FSF6-EZ (an easy-to-make medium adapted from FSF6 at Tufts and used by the cell bank: formulation and protocol for preparation)

  • TU-GFI-SCL3 is an immortalized suspension cell line developed by SCiFi Foods from domestic cattle (Bos taurus) connective tissue. TU-GFI-SCL3 was obtained by the Good Food Institute and deposited in the TUCCA Open Cell Bank. TU-GFI-SCL3 was reportedly used by SCiFi Foods in a submission to the FDA.

    Common name: Domestic cattle
    Growth Properties: Suspension
    Cell type: Fibroblast
    Immortalization status (reported by SCiFi Foods): Immortalized; TERT, P53 knockout
    Comments (reported by SCiFi Foods): Antibiotic resistance markers removed
    Developer: SCiFi Foods
    Media: Media formulations for TU-GFI-SCL3 cells can be found open-sourced by GFI here.

    • FSF4 (minimal medium reported by SCiFi Foods, not yet validated at Tufts: formulation)

  • TU-GFI-SCL4 is an immortalized suspension cell line developed by SCiFi Foods from domestic cattle (Bos taurus) connective tissue. TU-GFI-SCL4 was obtained by the Good Food Institute and deposited in the TUCCA Open Cell Bank. TU-GFI-SCL4 was reportedly cultured by SCiFi Foods in a 500L bioreactor format.

    Species: Bos taurus
    Common name: Domestic cattle
    Growth Properties: Suspension
    Cell type: Fibroblast
    Immortalization status (reported by SCiFi Foods): Immortalized; TERT, P53 knockout
    Comments (reported by SCiFi Foods): Antibiotic resistance markers removed
    Developer: SCiFi Foods
    Media: Media formulations for TU-GFI-SCL4 cells can be found open-sourced by GFI here.

Tufts-developed Immortalized Cells

Currently, Tufts-developed immortalized cells can be found through other providers. We will update this page as more cell lines are made available through the TUCCA Open Cell Bank.

  • Genetically immortalized adherent bovine satellite cells from kerafast or ABM
  • Spontaneously immortalized adherent mackerel satellite cells from kerafast
     

Acknowledgements

We are deeply grateful to the Culley Carlson Foundation for their pivotal support in getting the cell bank off the ground, the Astera Institute for funding initial expansion and banking of the SCiFi Foods cell lines, and the Good Food Institute for their continued collaboration. We would also like to thank Alexi Goranov (SCiFi Foods’ former VP of R&D) for his technical advice, and Joshua March (former co-founder & CEO) and Kasia Gora (former co-founder & CTO) for their support.

Lastly, the TUCCA Open Cell Bank is an initiative of the Tufts Cellular Agriculture Commercialization Lab. We are extremely grateful to members of the team who led this effort, notably Olivia Calkins and Olympe Jean, who were instrumental in its early progress.
