Allogeneic donor and iPSC master cell banks

Making cell therapies from a healthy donor or stem-cell line in advance, so patients get an off-the-shelf product instead of waiting weeks.

Off-the-shelf products use healthy-donor T or NK cells (Allogene, Caribou, Cellectis, Takeda/MD Anderson cord-blood NK) or induced pluripotent stem cell master banks (Fate Therapeutics, Century, Shoreline, Cellular Biomedicine) edited to avoid graft-versus-host disease and host rejection. Banking, donor eligibility, and comparability across thousands of doses from one bank are the manufacturing questions; durability of response is the clinical one.

How it works

A characterised master cell bank (donor or iPSC) is expanded, gene-edited to remove TCR and HLA class I, differentiated if needed, and cryopreserved in hundreds of doses per batch.

Strengths
  • Immediate availability
  • Lower cost per dose at scale
  • Consistent product
Limitations
  • Rejection limits persistence
  • Editing complexity
  • Donor-to-donor variability for primary-cell products
