Presented here is a useful protocol for lung fixation that creates a stable condition for histological evaluate of lung specimens from a mouse model of emphysema. The main advantage of this model is that it can fix many lungs with the same constant pressure without lung collapse or...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Here, we present a protocol for studying orthodontic tooth movement (OTM), serving as a suitable model for investigating the mechanisms of bone adaptation, root resorption, and the response of bone cells to mechanical stimuli. This comprehensive guide provides detailed information on the OTM model, micro-computed tomography acquisition, and subsequent...

This video demonstrates the utilization of a microfluidic device to study the interactions between tooth germ pulp and trigeminal ganglia. It showcases the placement of tissues inside the microfluidic device and provides a detailed visualization of trigeminal neurite growth toward the tooth germ through the device's microgrooves. Additionally, it highlights the role of tooth-derived molecular factors in promoting or inhibiting neurite extension into the tooth germ pulp, which is crucial for...

Here we detail a method to culture tooth germs in mandible slices using a tissue chopper. This method allows unique access to the tooth during development, providing excellent opportunity for manipulation and lineage tracing, not available using more traditional culture...

We present a protocol to establish a massive pontine hemorrhage model in a rat via dual injection of autologous...
