Biocompatible pH responsive sol-gel nanosensors can be incorporated into poly(lactic-co-glycolic acid) (PLGA) electrospun scaffolds. The produced self-reporting scaffolds can be used for in situ monitoring of microenvironmental conditions whilst culturing cells upon the scaffold. This is beneficial as the 3D cellular construct can be monitored in real-time without disturbing the experiment.

Interview: Bioreactors and Surfaced-Modified 3D-Scaffolds for Stem Cell Research

In the past many in vitro culture systems -- mainly monolayer cultures -- often suffered from the disadvantage that differentiated primary cells had a relatively short life-span and de-differentiated during culture. As a consequence, most of their organ-specific functions were lost rapidly. Thus, in order to reproduce better conditions for these cells in vitro, modifications and adaptations have been made to conventional monolayer cultures.

Here we present a fluorophore based imaging technique to detect cell viability on a non-transparent titanium scaffold as well as to detect glimpses of the scaffold impurities. This protocol troubleshoots the drawback of imaging cell-cell or cell-metal interactions on non-transparent scaffolds.

There is a critical need for 3D cancer models that capture heterocellular crosstalk to study cancer metastasis. Our study presents the generation of heteromulticellular stromal-epithelial in a scaffold and scaffold-free environment that can be used to study invasion and cellular spatial distributions.
FAQs
A key molecular link forms when integrins bind scaffold-associated surface ligands. This binding clusters adhesion proteins into focal adhesions, which connect the extracellular material to the cell’s cytoskeleton. That physical connection also activates signaling pathways, allowing cells to translate attachment into changes in spreading, migration, proliferation, or differentiation. Receptor-mediated adhesion therefore helps determine cell behavior on a scaffold.
Stiffness, porosity, topography, and biochemical composition act as distinct environmental cues. Together, they influence how cells attach to and sense the scaffold, which can alter spreading, migration, proliferation, differentiation, and matrix deposition. Changing one or more of these characteristics can therefore shift the biological response, even when the scaffold’s overall purpose remains unchanged.
Attachment initiates more than a physical connection. Signals activated through adhesion receptors and focal adhesions help cells interpret properties of the surrounding scaffold and coordinate their responses. These signals can influence whether cells spread, migrate, proliferate, differentiate, or deposit matrix. In bioengineering, this mechanism explains how material design can affect cell behavior without directly changing the cells themselves.
Bioengineers can adjust surface ligands, stiffness, porosity, topography, and biochemical composition to influence how cells attach and respond. The resulting cellular behaviors provide a basis for refining scaffold designs toward desired outcomes, such as improved matrix deposition, controlled differentiation, or better integration. This approach treats the scaffold as an active regulator of cell behavior rather than only a structural support.
Researchers can evaluate whether cells attach effectively and then examine changes in spreading, migration, proliferation, differentiation, and matrix deposition. Considering these outcomes together gives a broader view of scaffold performance than attachment alone. The pattern of responses can indicate whether the material’s physical and biochemical features are supporting the intended tissue-engineering or regenerative objective.
This area supports the design of biomaterials for tissue engineering, wound repair, organ models, and regenerative medicine. In each setting, researchers seek to control how cells interact with three-dimensional materials so that scaffolds integrate more effectively and encourage functional tissue development. The same principles also contribute to developing tissue replacements whose cellular responses are compatible with the intended application.
