Researchers step closer to custom-building new blood vessels

Researchers at Johns Hopkins have coaxed stem cells into forming networks of new blood vessels in the laboratory, then successfully transplanted them into mice. The stem cells are made by reprogramming ordinary cells, so the new technique could potentially be used to make blood vessels genetically matched to individual patients and unlikely to be rejected by their immune systems, the investigators say.

Key step in molecular 'dance' that duplicates DNA deciphered

Scientists have captured new details of the biochemical interactions necessary for cell division -- molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target. The research may suggest ways for stopping cell division when it goes awry.

Membranes in tight corners

Photosynthesis takes place in specialized membrane systems, made up of stacked disks linked together by unstacked planar leaflets. An LMU team has now identified a protein that tucks the membrane in at the edge of each stack.
