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.

By grafting beads soaked in growth factors or specific inhibitors of signaling pathways into developing embryos it is possible to directly test their effects in vivo. In this protocol beads are grafted into the limb bud to determine the effects of these molecules on gene expression and signal transduction.

This video describes orthotopic kidney auto-transplantation in a porcine model. This surgical procedure involves the transplantation of an animal's kidney graft at its original anatomical location. The model is used to investigate new treatments for end-stage kidney diseases in humans.
FAQs
Compatibility determines whether the grafted embryo can establish the tissue connection needed for continued development. A suitable rootstock provides a living interface through which water and nutrients reach the isolated embryo, while incompatibility can prevent that functional contact. Studying this relationship helps researchers examine how developing embryonic tissue interacts with supporting rootstock tissue during plant development.
Embryo grafting is particularly useful when an embryo cannot mature independently or when a cross produces embryos that are difficult to recover as plants. Placing such an embryo on a living rootstock supplies developmental support that it would otherwise lack. This makes the technique a recovery strategy for obtaining plants from wide or otherwise challenging breeding crosses.
The technique separates embryo development from the original seed context, allowing researchers to investigate development after the embryo has been isolated. Its outcome depends on whether the embryo establishes functional contact with the rootstock and continues developing. Consequently, graft compatibility and interactions between the two living tissues become experimental subjects, not merely technical concerns.
A basic workflow begins by excising the plant embryo under sterile conditions. Researchers then place it onto a prepared seedling or other compatible living rootstock, positioning the tissues so a functional connection can form. Continued development is assessed through the embryo’s ability to remain supported and progress toward a viable plant.
Sterility and rootstock preparation are central operational requirements. The embryo must be isolated without losing the opportunity to establish contact, while the seedling or rootstock must be living, compatible, and prepared to receive it. These conditions matter because the graft must connect effectively enough for the rootstock to supply water and nutrients during development.
In plant breeding, the method helps recover embryos from wide or otherwise difficult crosses and can accelerate the production of viable plants. In biological research, it supports studies of embryo development, graft compatibility, and interactions between developing tissues. Thus, the same procedure serves both a practical breeding objective and a broader investigation of plant developmental relationships.
