Differentiation of Neural Stem Cells to Neurons Using a Compartmentalized Microfluidic Device
0 Views •
2025
The video demonstrates the differentiation of neural stem cells (NSCs) using a microfluidic device comprising a somatic and an axonal compartment separated by a microgroove barrier. NSCs are introduced into the somatic compartment and are allowed to adhere. The NSCs differentiate into neurons inside the somatic compartment and extend axons through the microgroove barrier to the axonal compartment.

We report a concise procedure of fluorescence in situ hybridization (FISH) in the gonad and embryos of Caenorhabditis elegans for observing and quantifying repetitive sequences. We successfully observed and quantified two different repetitive sequences, telomere repeats and template of alternative lengthening of telomeres (TALT).

This protocol focuses on utilizing the inherent ability of stem cells to take cue from their surrounding extracellular matrix and be induced to differentiate into multiple phenotypes. This methods manuscript extends our description and characterization of a model utilizing a bilayered hydrogel, composed of PEG-fibrin and collagen, to simultaneously co-differentiate adipose-derived stem cells1.

The video demonstrates a method for generating excitatory cortical neurons from human-induced pluripotent stem cells (hiPSCs). Upon doxycycline induction, the hiPSCs overexpress neurogenin-2, a neural-specific transcription factor. By using specific media and co-culturing with astrocytes, this process facilitates the hiPSCs' differentiation into neurons with synaptic connections.

This video demonstrates the visualization of bacteria in deparaffinized bladder tissue from a urinary tract-infected patient. Fluorescently-labeled probe hybridized with bacterial 16s ribosomal RNAs reveals the tissue-associated bacteria and their distribution, providing valuable spatial insights into their density within the sample.
FAQs
Humidification changes the moisture conditions of air before it enters the respiratory tract. In a clinical humidifier, air may pass over heated water or receive fine droplets, increasing absolute humidity, meaning the amount of water vapor carried by the air. That added moisture helps limit drying and irritation in nasal and respiratory passages during respiratory support.
Temperature and water level are functional control variables, not merely maintenance details. Clinical use requires monitoring both so the humidified air remains appropriately regulated as it travels through the respiratory circuit. Maintaining these conditions supports the intended reduction of drying and irritation during oxygen therapy or mechanical ventilation, where moisture control is part of respiratory support.
The distinction lies in how moisture reaches the air stream. One design passes air over heated water, whereas another generates fine droplets. Both mechanisms can raise absolute humidity before air enters a respiratory circuit, mask, or other delivery system. This comparison helps describe the device’s operating pathway without implying that either mechanism suits every clinical situation.
Selection should match the intended clinical delivery route and the need to regulate moisture before air reaches the patient. Respiratory circuits, masks, and other delivery systems provide possible pathways. Clinicians therefore need to consider how the humidifier connects with the chosen support arrangement while maintaining attention to temperature and water levels throughout use.
During oxygen therapy or mechanical ventilation, humidification is integrated into the delivery arrangement so air receives added moisture before reaching the patient. The route may include a respiratory circuit, mask, or another delivery system. Monitoring temperature and water levels remains part of use because regulation must continue while respiratory support is being provided.
Cleaning is central to safe clinical use because the device handles water and supplies air that reaches a patient. Clinical guidance links selection and cleaning with limiting contamination risks. Cleaning should therefore be treated as part of humidifier management, alongside regulation of temperature and water levels, rather than as an optional step after respiratory support.
