Research

The current project is focusing on investigating the function of Wnt signaling in the regulation of human bone biology as well as whether Wnt signaling can be a target in the therapeutic intervention of human bone-related disorders including bone tumors. The multi-potent mesenchymal stem cells (MSCs) originating from the adult human bone marrow has been used as model cells to study the function of Wnt signaling in bone differentiatin and regeneration. The lab is also focusing on identification of small molecules that can modulate Wnt signaling activity.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr.Liu is not currently required to report Industry relationships.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website at http://icahn.mssm.edu/about-us/services-and-resources/faculty-resources/handbooks-and-policies/faculty-handbook. Patients may wish to ask their physician about the activities they perform for companies.
