Stem cells exist in an in vivo microenvironment that provides biological and physiochemical cues to direct cell fate decisions. How the stem cells sense and respond to these cues is still not clearly understood. Gold nanoparticles (AuNPs) have been widely used for manipulation of cell behavior due to their ease of synthesis and versatility in surface(More)
Gold nanoparticles (AuNPs) have been extensively explored for biomedical applications due to their advantages of facile synthesis and surface functionalization. Previous studies have suggested that AuNPs can induce differentiation of stem cells into osteoblasts. However, how the size and shape of AuNPs affect the differentiation response of stem cells has(More)
Rabbit corneal basal epithelial cells seeded onto fixed gelatin membranes or commercial collagen shields formed 3 to 5 cell layers after 1 to 3 weeks of culture at 35 degrees C in nutrient medium. The cells grew better, by comparison, in the collagen shields and eventually formed a multilayered tissue that resembled the stratified morphology of native(More)
