Published 08/12/2024 {{c1::Proteoglycans}}: polymerize to form negatively charged glycosaminoglycans (GAGs) which attract water → hydrated gel fills volume, resists c…
Published 08/12/2024 {{c1::Fibronectin}}: binds integrins to propel cells through CT for cell migration, e.g. inflammation and wound healing 
Published 08/12/2024 {{c1::Laminin}}: binds integrins and Type IV collagen for integrity of basal lamina
