   Sammanfattning : In about 2:10,000 births the external part of the ear, the auricle, is severely malformed or absent. Furthermore, tumors and trauma can cause defects to the auricle. LÄS MER

3. 7. Pain in Osteoarthritic Joints: Biological Signaling and 3D Models based on Imaging

   Författare :Birgitta Gatenholm; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; pain in knee joints; cartilage lesions; micro-computed tomography; 3D CAD models; neuropeptides;

   Sammanfattning : Osteoarthritis (OA) is the most common joint disease, causing disability in middle-aged and elderly patients worldwide and imposing a huge socioeconomic burden. OA of the knee joint is a major cause of joint pain and, along with back pain, it accounts for the two most-reported causes of chronic pain. LÄS MER

4. 8. Next generation bioengineering of lung tissue for transplantation

   Författare :Martina M. De Santis; Lungbioengineering och regeneration; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Lung transplantation is the only option for end-stage lung diseases, but organ shortage remains problematic. Generating lungs ex vivo could overcome shortages with current approaches being explored for lung tissue engineering utilizing a biologically derived, synthetic or hybrid scaffold which is seeded with cells and cultured ex vivo.

5. 9. Generation and investigation of neural microenvironment in health and disease

   Författare :Jakub Lewicki; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cells in our body are under the constant influence of intrinsic and extrinsic factors that modulate their behavior. Early on, starting during the development of the organism, growth factors, nutrients, oxygen, the extracellular matrix and contact with other cells affect essential processes such as proliferation, migration, differentiation and apoptosis.

7. 10. Recreating the microenvironment of the neurovascular unit

   Författare :Isabelle Matthiesen; Anna Herland; Thomas E. Winkler; Stéphanie Descroix; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microphysiological systems; neurovascular unit; induced pluripotent stem cells; extracellular matrix; hydrogels; in vitro models; mikrofysiologiska system; neurovaskulära enheten; inducerade pluripotenta stamceller; extracellulära matrisen; hydrogeler; in vitro modeller; Bioteknologi; Biotechnology;

   Sammanfattning : The neurovascular unit (NVU) comprises the blood-brain-barrier (BBB) and its surrounding astrocytes, pericytes and neurons that are embedded in the extracellular matrix (ECM). As the main function of the BBB is to protect the brain from inlet of pathogens and toxins, the specialized endothelial cells that keep the barrier tight will also hinder the passage of pharmaceuticals.
