Simple techniques are described for the rapid production of microfabricated neural culture systems using a digital micromirror device for dynamic mask projection lithography on regular cell culture substrates. These culture systems may be more representative of natural biological architecture, and the techniques described could be adapted for numerous applications.

We describe here the use of a pH-sensitive green fluorescent protein variant, pHluorin, to study the spatio-temporal dynamics of axon guidance receptors trafficking at the cell surface. The pHluorin-tagged receptor is expressed both in cell culture and in vivo, using electroporation of the chick embryo.

In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...

A technique to study NG2 cells and oligodendrocytes using a slice culture system of the forebrain and cerebellum is described. This method allows examination of the dynamics of proliferation and differentiation of cells within the oligodendrocyte lineage where the extracellular environment can be easily manipulated while maintaining tissue cytoarchitecture.
FAQs
Fluid flow generates mechanical cues, including shear stress, that can influence how cells behave within an engineered culture environment. The magnitude and pattern of these forces depend on fluid movement and mixing in the bioreactor. Reproducing such cues helps engineers create conditions that more closely represent changing environments in living systems and can support tissue maturation.
Mixing and perfusion help distribute nutrients and oxygen through the culture, while mass transfer describes their movement into the cells, tissues, or microorganisms being grown. Engineering these processes can reduce uneven exposure to essential resources and help maintain controlled dissolved-gas conditions. Better control of these variables may improve culture uniformity and cellular viability.
Static culture provides a comparatively unchanging environment, whereas Dynamic Culture allows physical and chemical conditions to change through controlled flow, mixing, perfusion, and regulated delivery. This difference adds mechanical stimulation and improves control over nutrient and oxygen transport. As a result, dynamic systems can model changing biological environments more effectively and support tissue maturation studies.
A bioreactor-based setup combines controlled fluid movement with regulation of temperature, pH, and dissolved gases. Engineers also establish appropriate mixing, perfusion, and delivery of nutrients or oxygen so that the cultured material receives a managed environment. Coordinating these variables is essential because both chemical conditions and mechanical cues influence cellular behavior and culture performance.
Researchers may choose this approach when they need to influence tissue maturation, improve culture uniformity, or maintain cell viability under conditions that include mechanical stimulation and controlled transport. In tissue engineering and regenerative medicine, the system provides a way to expose developing tissues to engineered flow and regulated nutrients or oxygen, supporting the study of more physiologically relevant growth environments.
Dynamic Culture can help investigators examine how cells, tissues, or microorganisms respond to changing physical and chemical conditions. In engineering research, it supports bioprocess development, tissue maturation studies, and biomaterials testing while providing experimental models of changing environments found in living systems. Outcomes may include information about viability, uniformity, cellular behavior, and the effects of shear stress.
