We describe an in vivo fluorescence imaging protocol to monitor muscle regeneration by GFP-labeled myoblasts after transplantation into skeletal muscles of both healthy and dystrophic mice. This protocol can be adapted to study muscle regeneration by transplantation of other types of cells and in other muscular conditions as well.

Determining donor cell engraftment presents a challenge in mouse bone marrow transplant models that lack well-defined phenotypical markers. We described a methodology to quantify male donor cell engraftment in female transplant recipient mice. This method can be used in all mouse strains for the study of HSC functions.

Source: Calvo-Rodríguez, et al. Fluorescence and Bioluminescence Imaging of Subcellular Ca2+ in Aged Hippocampal Neurons. J. Vis. Exp. (2015). This video demonstrates the use of fluorescence imaging to measure cytosolic calcium levels in short-term and long-term rat hippocampal cultures. By comparing young and aged neurons, it highlights how increased L-type voltage-gated calcium channel density and prolonged activation in aged neurons result in calcium overloading, a hallmark of neuronal aging.
FAQs
A suitable tissue niche supports transplanted cells by providing an appropriate location, access to nutrients, and an adequate blood supply. It also creates conditions that help donor cells survive and remain functional within the host. If cells reach a compatible niche, they are better positioned to self-renew or produce functional progeny, supporting durable activity rather than temporary persistence.
Donor cells must avoid immune-mediated rejection to remain established in the host over time. Rejection can prevent transplanted cells from surviving long enough to integrate or generate functional progeny. Examining immune interactions therefore helps researchers understand why a graft remains active or loses function, while also clarifying how host conditions influence the durability of transplantation and cell-based therapy.
Detection alone does not show that a transplant has achieved durable biological activity. Long-term engraftment requires evidence that transplanted cells remain established, continue functioning, and either self-renew or generate functional progeny over time. This distinction makes sustained integration and activity more informative than an early observation of donor-cell presence when researchers evaluate treatment stability.
Evaluation focuses on whether transplanted cells or tissues show durable integration and activity within the host. Researchers assess sustained establishment, survival, and function rather than relying only on an initial response. These measurements help determine whether a transplantation strategy produces stable biological effects and provide evidence about host–graft interactions in experimental or therapeutic settings.
Long-term engraftment is especially relevant to hematopoietic stem cell transplantation, regenerative medicine, and experimental models of tissue repair. In each setting, durable establishment and function help indicate whether transplanted material contributes meaningfully to the intended biological outcome. The resulting information can guide assessment of treatment stability and the capacity to restore damaged or diseased tissues.
Patterns of durable integration and activity show how transplanted material responds to the host environment over time. They can indicate whether the graft reaches a suitable niche, receives adequate support, avoids immune-mediated rejection, and maintains functional output. Studying these relationships helps biology researchers identify conditions associated with successful transplantation and improve approaches for cell-based therapy and tissue repair.
