Mispro Expands Boston Footprint with Contract Vivarium Facility at Southline

Mispro has announced the opening of its eighth Boston-area contract vivarium, located at Southline Boston in Dorchester—reinforcing its role as the region’s most deeply embedded and consistently scaled vivarium space and services provider.

Located within Southline’s 700,000+ square foot life sciences campus, the new facility expands Mispro’s support for early- and growth-stage biotechs across Greater Boston. As the first company to introduce the contract vivarium (CV) model to the metro area, Mispro remains a critical partner to venture-backed startups and established programs seeking speed, control, and reproducible data in preclinical development.

“With each new facility, we’re investing in more than square footage—we’re expanding access to a smarter, de-risked model for in vivo research,” said Yohan Tessier, President & COO of Mispro. “The contract vivarium option reduces infrastructure burdens while keeping scientific control where it belongs, which is with the biotech teams who are driving discovery forward.”

Southline is also home to Portal Innovations, a leading early-stage venture firm and life sciences incubator. The proximity of Mispro’s vivarium services offers immediate operational advantages to Portal’s member companies and other tenants.

”Having Mispro onsite brings in vivo capacity directly into the heart of our ecosystem, giving early-stage teams immediate access to high-quality preclinical capabilities,” said Portal’s Executive Director in Boston, Tatiana Yglesias. “This streamlined access supports lean operations, accelerates timelines, protects IP, and meaningfully de-risks development—key advantages in today’s fast-moving and capital-conscious funding environment.”

To date in 2025, 75% of biotech M&A activity has involved companies conducting studies in Mispro facilities. The company currently supports 45 Boston-area biotechs and continues to grow alongside the region’s expanding R&D ecosystem.

“This expansion reflects our commitment to enabling science that moves—not just forward, but faster,” added Tessier.

Mispro’s Southline contract vivarium facility is set to open in October. Learn more about the location here.
