08:18 AM EDT, 09/10/2025 (MT Newswires) -- BioHarvest Sciences ( BHST ) said Wednesday it advanced its proprietary botanical synthesis platform by successfully producing plant-based exosomes at scale in its VINIA bioreactors.

The production of exosomes adds a potential new revenue stream from products and contract development and manufacturing organizations, the company said.

BioHarvest's exosomes contain viniferin and are designed to improve absorption and bioavailability in the skin compared with conventional formulations, the company said.

The scaled process combines light-permeable VINIA reactors with optimized growth media to drive higher yields and consistent cargo quality for skincare, health, and pharma customers, BioHarvest said.

The company said it expects to be positioned to launch a viniferin-carrying skincare application within 18 to 24 months.
