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 put women on fertile ground

Stem cells from the ovaries of reproductive age women can give rise to cells that appear to be mature oocytes, suggesting that women can produce more eggs than the batch they are born with. The findings, reported in the March 2012 issue of Nature Medicine, open the door to a new generation of assisted fertility treatments.

Germline stem cells that produce oocytes in vitro and fertilization-competent eggs in vivo have been identified in and isolated from adult mouse ovaries. Here we describe and validate a fluorescence-activated cell sorting-based protocol that can be used with adult mouse ovaries and human ovarian
