Bioengineered hierarchical bonelike compartmentalized microconstructs using nan...
Bjørge, Isabel M.; Sousa, Bárbara M. de; Patrício, Sónia G.; Silva, Ana Sofia; Nogueira, Liebert P.; Santos, Lúcia F.; Vieira, Sandra I.Fabrication of vascularized large-scale constructs for regenerative medicine remains elusive since most strategies rely solely on cell self-organization or overly control cell positioning, failing to address nutrient diffusion limitations. We propose a modular and hierarchical tissue-engineering strategy to produce bonelike tissues carrying signals to promote prevascularization. In these 3D systems, disc-shaped...
Hipster microcarriers: exploring geometrical and topographical cues of non-sphe...
Bjørge, Isabel M.; Correia, Clara R.; Mano, João F.Structure and organisation are key aspects of the native tissue environment, which ultimately condition cell fate via a myriad of processes, including the activation of mechanotransduction pathways. By modulating the formation of integrin-mediated adhesions and consequently impacting cell contractility, engineered geometrical and topographical cues may be introduced to activate downstream signalling and ultimat...
Cell behavior within nanogrooved sandwich culture systems
Bjørge, Isabel M.; Salmeron-Sanchez, Manuel; Correia, Clara R.; Mano, João F.Grooved topography and inherent cell contact guidance has shown promising results regarding cell proliferation, morphology, and lineage-specific differentiation. Yet these approaches are limited to 2D applications. Sandwich-culture conditions are developed to bridge the gap between 2D and 3D culture, enabling both ventral and dorsal cell surface stimulation. The effect of grooved surface topography is accessed ...
