Stem cells used to make “heart disease-on-a-chip”

Harvard scientists have merged stem cell and ‘organ-on-a-chip’ technologies to grow, for the first time, functioning human heart tissue carrying an inherited cardiovascular disease.

The research appears to be a big step forward for personalized medicine, as it is working proof that a chunk of tissue containing a patient’s specific genetic disorder can be replicated in the laboratory.

The work, published in Nature Medicine, is the result of a collaborative effort bringing together scientists from the Harvard Stem Cell Institute, the Wyss Institute for Biologically Inspired Engineering, Boston Children’s Hospital, the Harvard School of Engineering and Applied Sciences, and Harvard Medical

Stem cells to repair teeth

A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. The research, led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences (SEAS), lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.

The team used a low-power laser to trigger human dental stem cells to form dentin, the hard tissue that
