ENGRAFTMENT OF T CELLS
TRANSFECTED USING SOLUPORE

IS SUPERIOR COMPARED WITH
ELECTROPORATION-BASED SYSTEMS
S
olupore is a vector-free intracellular delivery platform that enables
development and manufacture of cell therapies. Membrane disruption-
based methods, such as Solupore
®
, that enable intracellular delivery of various
cargotypesforclinicalapplicationshavebeenproposedasattractivecandidates
as next-generation delivery modalities because of potential benefits for safety,
regulation and production. Electroporation is the most widely used method
currently, this includes electroporation-based methods such as nucleofection,
however disadvantages include toxicity and proliferation stalling. Solupore
®
uses reversible permeabilization to achieve rapid intracellular delivery of
cargos with varying compositions, properties and sizes. A permeabilizing
delivery solution containing a low level of ethanol is used as the permeabilizing
agent. The technology achieves intracellular delivery and subsequent reversal
of cell permeabilization by precisely controlling the contact of the target cells
with this solution. The process is rapid and cargo transfers directly into the
cytoplasm by diffusion in an endocytic-independent manner. We have termed
the method soluporation. Comparisons of the phenotype and functionality
of primary human T cells following soluporation (Solupore
®
), nucleofection
(4D-Nucleofector
TM
) and electroporation (Neon
®
) are outlined in this work. The
extent to which the transfection systems perturb T cells was investigated as
well as the effects on cell functionality. The results presented demonstrate that
the Solupore
®
technology does not perturb gene expression or cell surface
markers in T cells. Furthermore, cell proliferation and
in vivo
engraftment is
superior in soluporated cells compared with nucleofected cells. Thus, the
Solupore technology is gentle yet highly reproducible, automated, and scalable
and has the potential to enable a broad range of T cell engineering applications.
