Intervening to stop bone loss

A study led by Shuying (Sheri) Yang of the School of Dental Medicine identified a new role for a protein that keeps osteoclasts—the cells that break down bone—in check, and may guide the development of new therapies to counter bone loss.

Deconstructing the mechanics of bone marrow disease

Acollaborative team developed an alginate-based hydrogel system that mimics the viscoelasticity of the natural extracellular matrix in bone marrow. By tweaking the balance between elastic and viscous properties in these artificial ECMs, they could recapitulate the viscoelasticity of healthy and scarred fibrotic bone marrow, and study the effects on human monocytes placed into these artificial ECMs. (Image: Adam Graham/Harvard CNS/Wyss Institute at Harvard University)

Deconstructing the mechanics of bone marrow disease

A new understanding of how mechanical features of bone marrow affect resident immune cells in a fibrotic cancer points to future therapeutic strategies for cancers and fibrotic diseases.

Shapeshifting microrobots can brush and floss teeth

In a proof-of-concept study, researchers from the School of Dental Medicine and School of Engineering and Applied Science shows that a hands-free system could effectively automate the treatment and removal of tooth-decay-causing bacteria and dental plaque.

    How one inflammatory disorder exacerbates another

    Researchers from the School of Dental Medicine and colleagues from Dresden, Germany demonstrate that an association between conditions such as severe gum disease and arthritis is traceable to the bone marrow.
