New microscope could allow surgeons to inspect tumor margins within minutes

When surgeons remove cancer, one of the first questions is, "Did they get it all?" Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer.

Pig stem cells offer a new way to grow human organs for transplantation

In a new paper published in Stem Cell Reports, Bhanu Telugu and co-inventor Chi-Hun Park of the University of Maryland (UMD) Department of Animal and Avian Sciences show for the first time that newly established stem cells from pigs, when injected into embryos, contributed to the development of only the organ of interest (the embryonic gut and liver), laying the groundwork for stem cell therapeutics and organ transplantation.

Researchers study the mechanisms of skin aging

The ageing process is most apparent on the skin. In the newly opened "SKINMAGINE" (Multimodal Imaging of Aging and Senescence of the Skin) Christian Doppler Laboratory, dermatologists from MedUni Vienna have joined forces with biotechnologists from the University of Natural Resources and Applied Life Sciences Vienna and chemists from Vienna University of Technology, as well as the company Chanel, to study the interaction of metabolism, cellular communication and cellular quality control in skin ageing accelerated by environmental stress.
