   Abstract : Stem cells have a great potential to bring about advancements in fields like developmental biology, drug discovery, cancer biology and tissue engineering. In order to be able to use stem cells to their full potential, it is important to have control over their behavior. READ MORE

4. 2. Imaging-based methods for NK cell studies at the single-cell level

   Author : Quentin Verron; Björn Önfelt; Niklas Sandström; Michael Dustin; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; NK cells; microscopy; single-cell; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

   Abstract : The immune system provides defense against infectious agents such as viruses, bacteria and parasites. Besides eliminating extracellular agents, the immune system also constantly monitors our own cells for signs of transformation, including tumor development and virus infection. READ MORE

5. 3. Shape Matters : Characterization of Weak Interactions and Macrocycles by Conformational Analysis

   Author : Stefan Peintner; Máté Erdélyi; Oliver Zerbe; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : When studying conformational ensembles, it is most challenging to identify and characterize rapidly interconverting individual conformers. A precise description of the structural dynamics, however, rewards viable knowledge on conformation stabilizing forces as well as on the impact of external influences on the conformer composition.

6. 4. Studies on various culture systems for chondrocytes and osteoblasts

   Author : Juha Prittinen; Mikko Lammi; Minna Kellomäki; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; chondrocyte; osteoarthritis; surface materials; topography; tissue engineering; mechanical stimulation; Medical Cell Biology; medicinsk cellbiologi;

   Abstract : Osteoarthritis and osteochondral defects are ailments that are increasing in frequency as the lifespan of the population increases and sedentary lifestyle becomes more common. Osteoarthritis is an inflammatory disease that causes the progressive degeneration of articular surfaces and the underlying bone. READ MORE

7. 5. Water Fluxes and Cell Migration : How Aquaporin 9 Controls Cell Shape and Motility

   Author : Thommie Karlsson; Karl-Eric Magnusson; Roger Karlsson; Linköpings universitet; []
   Keywords : ;

   Abstract : Prerequisites for all modes of cell migration are cell-substratum interactions that require a sophisticated interplay of membrane dynamics and cytoskeletal rearrangement. Generally, a migrating cell is polarized with a distinct rear and front, from which it extends a wide and thin membrane protrusion- lamellipodium, small fingerlike projections- filopodia, and membrane blisters- blebs.
