Human colon stem cells have been identified and grown in a petri dish in the lab for the first time. This achievement, made by researchers of the Colorectal Cancer Lab at the Institute for Research in Biomedicine (IRB Barcelona) and published in Nature Medicine, is a crucial advance towards regenerative medicine. Throughout life, stem cells of the colon regenerate the inner layer of our large intestine in a weekly basis. For decades scientists had evidences of the existence of these cells yet their identity remained elusive. Scientists led by the ICREA Professor and researcher at the Institute for Research in Biomedicine (IRB Barcelona) Eduard Batlle discovered the precise location of the stem cells in the human colon and worked out a method that allows their isolation and in vitro expansion, that is their propagation in lab-plates (petri dishes).

Doctors can now make a stroke diagnosis using an iPhone/Android app with close to the same accuracy as a diagnosis at a medical computer workstation, researchers from the University of Calgary's Faculty of Medicine have shown in a new study. The Resolution MD Mobile app lets physicians view and manipulate remote medical images in high-resolution 3-D on the iPhone or Android phone, allowing for a quick diagnosis for the treatment of stroke, cardiac arrest, or other emergencies.
