Why Vertical-Wheel

Built For This Cell Type.

Size control through every stage

Homogeneous low-shear mixing keeps aggregate size distributions narrow across a multi-week differentiation, the critical quality attribute for islet identity and function.

Yield that scales faster than volume

A five-fold volume increase delivered twelve times more islets with no quality compromise, so a process developed small carries its economics upward.

Function confirmed in vivo

Islets manufactured this way were glucose-responsive in vitro and reversed diabetes in every transplanted animal.

Applications

  • SC-islets (diabetes)
  • Directed differentiation
  • Aggregate culture
  • hiPSC / PSC expansion
  • Disease modeling

Systems for This Cell Type

Each system carries the note explaining why it suits this cell type.

  • PBS-MiniIslet differentiation development
  • PBS-MiniPROParallel differentiation screening
  • PBS-3Scaled differentiation (GMP runs)
  • PBS-15Clinical-scale islet batches
  • PBS-80Differentiation demonstrated to 50 L
183,000

A single 0.5 L Vertical-Wheel® batch produced roughly 183,000 islet-equivalents (IEQ) of glucose-responsive SC-islets, enough by published dosing to treat a ~34 lb patient, and the SC-islets reversed diabetes in all fifteen transplanted mice.
