Skin tattooing is a potent and safe way to delivery DNA vaccine intradermally. Here, a DNA plasmid encoding EGFP is delivered by tattooing to the skin of a laboratory mouse, and the expression of EGFP in the skin cells is then inspected by confocal microscopy.

A Technique for Human Skin Grafting in a Mouse Model

This video demonstrates a method for grafting human skin onto an immunodeficient mouse with a suppressed neutrophil response. The method involves applying human split-thickness skin to the mouse's graft bed, sealing it, and covering it for recovery. Eventually, the human skin adheres to the mouse's skin, establishing vascularization and circulation, resulting in a successful skin xenograft.

This protocol uses multi-view stereo to generate three-dimensional (3D) models out of uncalibrated sequences of photographs, making it affordable and adjustable to a surgical setting. Strain maps between the 3D models are quantified with spline-based isogeometric kinematics, which facilitate representation of smooth surfaces over coarse meshes sharing the same parameterization.

A Technique to Assess the Immune Response against an Antigen by Inducing Skin Inflammation

2025
This video demonstrates an in vivo technique to assess a test antigen by inducing skin inflammation in a murine model. The test antigen—a hapten in an oil/acetone solution—is topically applied to the skin of the mouse ear, and inflammation of the skin is assessed after an adequate period.
FAQs
Spatial control comes from directing repeated needle penetrations to selected skin locations. Each pass deposits pigment or another material within the dermis rather than leaving it only at the surface. This localized delivery allows researchers to create persistent markings or interfaces with defined positions, which is important for experimental tracking and for designing skin-based bioengineering systems.
After deposition, pigment particles remain locally while the tissue undergoes repair and immune-cell responses. These biological processes influence how the material is retained within the skin and help support the persistence of the resulting marking. In bioengineering studies, this interaction between deposited material and tissue response is central to creating durable visual or functional interfaces.
The technique places material in the dermis, where it can be retained locally as the surrounding tissue responds to the procedure. This location supports markings that remain spatially defined instead of functioning only as temporary surface signals. The same principle makes skin useful as an accessible substrate for engineered markers and tattoo-like biosensors.
Ordinary pigments primarily create a visible marking, whereas functional materials can form an interface that reports biochemical or physiological changes at the skin surface. This distinction expands the technique from visual identification or tracking to sensing. In bioengineering, the material choice therefore determines whether the tattoo-like interface serves mainly as a marker or as a diagnostic signal.
A basic workflow selects the intended skin location, positions the needle over the desired pattern or interface, and repeatedly penetrates the epidermis to deposit pigment or functional material in the dermis. The procedure then relies on local tissue repair and immune responses to retain the deposited material. This sequence produces either a durable marking or a skin-based engineered interface.
Researchers can use persistent, spatially defined markings to identify locations, distinguish experimental regions, or follow a feature over time. Its value comes from combining visible placement with retention in skin, allowing the marking to remain associated with a selected site. In bioengineering, this supports experiments that require accessible and durable spatial reference points.
Tattoo-like biosensors use the skin as an accessible platform for engineered signals. Instead of serving only as a visual marker, the deposited functional material can report biochemical or physiological changes at the skin surface. This approach connects minimally invasive fabrication with diagnostics and personalized biointerfaces, offering a way to position sensing functions directly on an individual’s skin.
