Deficits in muscular strength occur in many clinical conditions such as motor neuron disease. The inverted screen and weight lifting tests described here measure strength in mice almost exclusively, with minimal influence of factors such as coordination.

The mouse small bowel transplantation model has been recognized as an important tool to study mechanismes of immune rejection and screen new immunosuppressive drugs. However, this model is limited to use because the techniques involved is an extremely technically challenge. Now we introduce the modified technique.

Video-oculography is a very quantitative method to investigate ocular motor performance as well as motor learning. Here, we describe how to measure video-oculography in mice. Applying this technique on normal, pharmacologically-treated or genetically modified mice is a powerful research tool to explore the underlying physiology of motor behaviors.
FAQs
The albumin promoter restricts human diphtheria toxin receptor expression to liver parenchymal cells in this model. When diphtheria toxin is administered, it can bind those receptors and trigger receptor-mediated hepatocyte death. This targeted injury is important because it depletes the intended liver cell population rather than relying on nonspecific damage.
The severe combined immunodeficiency background is important because it limits rejection of transplanted cells. That feature allows human hepatocytes to remain in the mouse after transplantation, making it possible to examine their survival, repopulation, and function within an injured liver. In this way, the model links selective host-cell depletion with analysis of human cell engraftment.
Selective depletion creates available space in the liver for engrafted human hepatocytes. Following injury, investigators can assess whether transplanted cells survive, repopulate the tissue, and perform relevant hepatic functions. The model therefore provides more than a transplantation endpoint: it connects host-cell loss with subsequent behavior of human liver cells in a living system.
A supported workflow starts with Alb-treck/scid mice, administration of diphtheria toxin to induce hepatocyte depletion, and transplantation of human hepatocytes into the injured animals. Subsequent analyses focus on cell survival, liver repopulation, and function. The overview does not specify toxin dose, timing, cell number, or surgical details, so those parameters require protocol-specific determination.
Post-transplantation assessment can address three central outcomes: whether human hepatocytes survive, whether they repopulate the injured liver, and whether they retain or display hepatic function. Investigators can also examine host responses to these human cells. Together, these readouts connect engraftment with the model’s translational relevance.
Their main value lies in studies that need human liver cells to be evaluated within a living animal after selective liver injury. Applications supported by the model include investigating liver disease, evaluating cell therapies, studying hepatic pathophysiology, and assessing host responses to transplanted human hepatocytes. This supports translational analysis of human liver-cell behavior.
