Our Science

Allogeneic cell therapy for life-threatening conditions in the most vulnerable populations.

Our approach uses mesenchymal stem cells to repair, regenerate or replace damaged or diseased cells in the body

Lomecel-B® (laromestrocel)

A mesenchymal stem cell therapy with diverse therapeutic potential

Laromestrocel is a living cell product made from specialized cells isolated from the bone marrow of young healthy adult donors. These specialized cells, known as mesenchymal stem cells (MSCs), are essential to our endogenous biological repair mechanism. MSCs have been shown to perform a number of complex functions in the body, including the formation of new tissue. They also have been shown to respond to sites of injury or disease and secrete bioactive factors that are immunomodulatory and regenerative.

We believe that laromestrocel may have multiple potential mechanisms of action that may lead to anti-inflammatory, pro-vascular regenerative responses, and therefore may have broad application for a range of rare and aging-related diseases.


Lomecel-B® (laromestrocel) is a biologic therapy comprised of allogeneic (donor-derived) mesenchymal stem cells (MSCs) isolated from bone marrow of healthy young adults.

Cells are culture-expanded – replicated under controlled laboratory conditions – into the billions.

After expansion cycles called “passages”, the cells are harvested, separated into doses (e.g. 50 million cells), and frozen until future use in patients
