This minimal intervention setup has been applied to demonstrate the role of glycerine in lubrication and damage prevention of cornea.The friction coefficient between glass against

Type IV collagen, laminin, and fibronectin promote the adhesion and migration of rabbit lens epithelial cells in vitro. Investigative Ophthalmology &

LMWG alone and in combination with laminin derivatives (IKVAV+YIGSR), fibronectin and collagen derivatives (RGD+DGEA), and with a basement membrane peptide mixture were studied in

De fysisch-chemische eigenschappen van de nanovezels beïnvloeden mede het celgedrag en kunnen daarmee worden gebruikt om het gedrag van cellen te regelen in de richting

proteínas da membrana basal: laminina, colagénio e fibronectina foram utilizados para investigar os efeitos da composição da matriz em LEC (células epiteliais da lente) e avaliar

I would like to thank all the colleagues with whom I worked in the department especially, Hilde, Anna, Adhi, Simon, Joana, Niar, Helen, Arina, Song, Bu, Bart, Brian, Vera,

Self-assembling nanofiber hydrogels to attenuate epithelial mesenchymal transition in lens epithelial cells.. da Cruz Barros,

expression levels of connexins and ion channels in human adult epicardial cells during EMT is associated with less cell–cell cou- pling and a decrease in conduction velocity..
