Researchers at Brigham and Women’s Hospital (BWH) have identified a human lung stem cell that is self-renewing and capable of forming and integrating multiple biological structures of the lung. “This research describes, for the first time, a true human lung stem cell,” said Piero Anversa, director of the Center for Regenerative Medicine at BWH and [Sign in to read the full article...]

The machine looks like the offspring of an Erector set and an inkjet printer but instead of just putting down ink on paper, they stack up layers of living material, i.e. “goo”, to make 3-D shapes which can be made into a new body part, according to a recent article in the Washington Post.  In [Sign in to read the full article...]

Researchers at Johns Hopkins report they have demonstrated that human liver cells derived from adult cell coaxed into an embryonic state can engraft and begin regenerating liver tissue in mice with chronic liver disease.  The findings suggest that the liver cells from “induced-pluripotent stem cells (iPSCs)” could one day be used as an alternative to [Sign in to read the full article...]

A 42-year-old patient with leukemia appears to have no detectable HIV in his blood and no symptoms after a stem cell transplant from a donor carrying a gene mutation that confers natural resistance to the virus that causes AIDS, according to a report published in the New England Journal of Medicine.  “The patient is fine,” [Sign in to read the full article...]

Despite concerns that surgeon fatigue is leading to dangerous complications for patients and data showing worse outcomes for many patients who undergo surgery at night, new Johns Hopkins research suggests that in the case of heart and lung transplants, the time of the day when the transplant is performed has no affect on patient survival.
