HARTFORD, Conn. — The Jackson Laboratory is partnering with cancer specialists at two Connecticut hospitals to study new approaches to cancer treatment for children and adults.

The collaboration between the Maine-based research lab, Hartford Hospital and Connecticut Children’s Medical Center, was announced Tuesday.

Jackson scientists and doctors from the hospitals plan to use specialized mice as stand-ins for human cancer patients in their research. They are studying cancers with a high relapse risk.

Gov. Dannel P. Malloy said the partnership will advance cancer treatment and position Connecticut as a leader in genomic medicine.

Jackson is receiving nearly $300 million in forgivable loans and research grants from the state to help build a $1.1 billion genomic research facility on the grounds of the University of Connecticut Health Center in Farmington.
