Non-Invasive Visualization of Nailbed Microvascular Morphology in Mice Using Capillaroscopy

Area of Science:

• Microcirculation research
• Animal models in disease research
• Non-invasive imaging techniques

Background:

• Nailfold capillaroscopy (NFC) is crucial for diagnosing systemic diseases in humans by assessing microvascular function.
• Translating NFC findings to animal models is difficult due to invasive or expensive methods.
• There is a need for accessible, non-invasive techniques to study peripheral microvasculature in animal research.

Purpose of the Study:

• To develop and present a straightforward protocol for nailbed capillaroscopy in mice.
• To enable easy and cost-effective assessment of microvascular morphology in mouse models.
• To facilitate the study of peripheral microvascular abnormalities in various mouse disease models.

Main Methods:

• Application of capillaroscopy technique to the nailbed of mice.
• Imaging of nailbed microvasculature in wild-type mice (SV129/S6 and C57/B6J strains).
• Development of a protocol for non-invasive microvascular assessment.

Main Results:

• Successful application of capillaroscopy to the mouse nailbed.
• Acquisition of representative images of nailbed microvascular architecture in two common mouse strains.
• Demonstration of capillaroscopy as a viable non-invasive imaging tool for mouse peripheral microvasculature.

Conclusions:

• The developed nailbed capillaroscopy protocol offers a simple, inexpensive, and non-invasive method for assessing mouse microvasculature.
• This technique can significantly aid research in mouse models of diseases involving peripheral microvascular dysfunction.
• Further studies are warranted to apply this method across diverse mouse disease models.
