The video describes the preparation of a micropatterned substrate to study cell phenotype specification. A protein-coated micropatterned PDMS stamp is used to transfer the micropattern on a PDMS-coated coverslip. The coverslip is then treated with a surfactant to hinder cell adhesion at the unwanted surfaces. Cells are then added to settle in the pattern and incubated for further analysis.

Here we describe two assays that have been established to study age-dependent neurodegeneration of dopaminergic (DA) neurons in Drosophila: the climbing/startle-induced negative geotaxis assay which allows to study the functional effects of DA neurons degeneration and the tyrosine hydroxylase immunostaining which is used to identify and count DA neurons in whole brain mounts.

This video demonstrates evaluating the neurodegenerative effects of a test chemical on Caenorhabditis elegans with fluorescently tagged neurons. Normal neurons show bright fluorescence of intact soma and processes, while diminished fluorescence, swollen soma, and punctuated processes indicate neurodegeneration.
FAQs
These measurements describe different levels of neuronal organization. Morphology reveals cellular structure, gene and protein expression indicates molecular state, and electrical activity shows functional behavior. Considering them together helps researchers determine whether observed traits are related and how cellular characteristics may influence neuronal operation, rather than relying on a single measurement that captures only one aspect.
Researchers can compare cell morphology, gene or protein expression, neurotransmitter identity, and electrical activity. Differences across these characteristics may separate neuronal populations or indicate changes within the same population. Examining several traits provides a more informative profile for relating a cell to its development, operation, neural circuit, or associated behavior.
Cellular measurements become more meaningful when linked to larger nervous-system functions. Connecting phenotype data with neural circuits or behaviors can show how a change in neuronal structure, molecular state, or activity relates to system-level outcomes. This relationship supports interpretation of how cellular alterations may contribute to normal operation, disease, injury, or treatment response.
A study may combine microscopy, molecular profiling, and electrophysiological recording. Microscopy assesses morphology, molecular profiling examines gene or protein expression and neurotransmitter identity, and electrophysiology evaluates electrical activity. The selected combination depends on which neuronal characteristics researchers need to compare, allowing structural, molecular, and functional findings to be interpreted together.
Researchers apply these studies to questions involving neuronal development, neurodegenerative disease, injury, and therapeutic response. The approach can reveal whether cellular traits change under a disease or injury condition and whether a treatment is associated with altered neuronal characteristics. These findings help evaluate biological models and investigate how cellular changes relate to nervous-system function.
The results can identify cellular changes that may be relevant to neural dysfunction and can support evaluation of models, biomarkers, and potential treatments. By comparing phenotype measurements across conditions, researchers can determine whether structural, molecular, or functional traits differ and assess how those differences may alter nervous-system function or reflect a therapeutic response.
