Source: Matthysse, A. G. Adherence of Bacteria to Plant Surfaces Measured in the Laboratory. J. Vis. Exp. (2018).This video demonstrates the evaluation of bacterial attachment to plant roots using phase-contrast microscopy. Root samples from seedlings incubated with bacteria are first mounted to check for free bacteria. The samples are then washed to remove loosely attached bacteria and remounted using a suitable coverslip to prevent damage. Finally, the number of bacteria attached to the root...

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that physical...

The temporal and spatial resolution of genetic manipulations determines the spectrum of biological phenomena that they can perturb. Here we use temporally and spatially discrete in vivo electroporation, combined with transgenic lines of zebrafish, to induce expression of a GFP transgene specifically in neurons of the developing olfactory bulb.
FAQs
Surface treatments improve the interactions between neuronal cells and the culture surface, helping anchor both cell bodies and neurites. Laminin and poly-D-lysine are examples of materials used to modify that surface. In parallel, integrin-mediated signaling contributes to attachment, linking the physical interface with cellular signals that help maintain neuronal positioning during culture.
Stable adhesion preserves the position and shape of cell bodies and neurites during culture, making morphological changes easier to interpret. It also supports network formation, so investigators can examine neural organization rather than changes caused by unstable cells. This is especially important when comparing experimental conditions or tracking development over time.
Integrin-mediated signaling helps convert contact with a modified culture surface into an anchoring response. This matters because attachment is not only a physical property of the coating; signaling also supports the spatial stability of neuronal cell bodies and neurites. Maintaining that stability provides a more dependable foundation for studying morphology and network formation.
A basic workflow begins by modifying the laboratory culture surface with an attachment-supporting material, such as laminin or poly-D-lysine, before examining neuronal cultures. The treated surface is then used to support cell bodies and neurites. Investigators can assess whether attachment and spatial stability are sufficient for the planned neural measurements.
Improved attachment supports imaging and electrophysiology by keeping neuronal cell bodies and neurites spatially stable during observation or measurement. It also strengthens the consistency of cell-based assays. Depending on the study, investigators can use these cultures to examine neurite outgrowth, synaptic development, neurotoxicity, or neural tissue engineering outcomes.
Neuronal attachment enhancement is useful when experiments depend on preserved neuronal structure or organized cultures. Relevant examples include studies of neurite outgrowth, synaptic development, neurotoxicity, and neural tissue engineering. It also supports cell-based assays, where consistent attachment can help investigators interpret biological responses across culture conditions.
