SXStemXO

Platform

A modular EV platform from discovery to translation.

StemXO brings source-cell biology, EV production, characterization and disease-specific development into one coherent platform.

Lipid bilayer

Protective lipid membrane

A natural, cell-derived membrane that protects cargo and lets vesicles move between cells in ways implanted stem cells cannot.

  • Avoids immunorejection and tumorigenesis risks of cell transplantation
  • Blood-brain barrier permeable
  • Can be engineered to target specific cell types

Source biology and delivery

Where our vesicles come from, and how they reach patients.

Umbilical cord MSCs

Human umbilical cord mesenchymal stem cells are the primary source for StemXO's vesicles, isolated and preserved under controlled conditions.

  • Primary source of the Mito-EV platform
  • Repeatable isolation and preservation process
  • Regenerative paracrine signaling

Defined biology. Defined product. Defined path to translation.

One platform. Multiple therapeutic paths.

StemXO is building the product definition, analytical strategy, potency framework and manufacturing process needed to move promising EV biology toward translation.
