   Sammanfattning : Flavors of taste are detected by a set of microscopical cellular aggregates called the taste buds, present in different arrangements on the upper surface of the tongue and other areas in the mouth. Taste buds are chemosensors that can detect different taste qualities such as sweet, sour, bitter, salt and umami. LÄS MER

7. 5. The role of N-cadherin and S1P/S1P1 in pancreas development

   Författare :Jenny Johansson; Stamcellscentrum (SCC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Organogenesis of epithelial organs requires interaction between epithelial and mesenchymal tissues. During pancreas development, mesenchyme-derived structures induce specification, growth and differentiation of pancreatic epithelial cells. LÄS MER
