The ability to differentiate into many cell types and the capacity to multiply like undifferentiated cells make stromal cells multipotent cells. The therapeutic potential of MSCs, such as cell therapy or tissue regeneration, is the subject of extensive research, and MSCs are regarded as potent instruments in veterinary regenerative medicine. Due to their immunosuppressive, immunomodulatory, and anti-inflammatory qualities as well as their minimal teratogenic risk as compared to pluripotent stem cells, they are the most popular type of adult stem cells in clinical studies. The current state of knowledge on MSCs’ basic biology is described in detail in this review. In order to provide an overview of therapeutic developments based on MSCs in dogs and cats, we concentrate on the traits and properties.


Muscle regeneration is a complex and dynamic process that plays a pivotal role in maintaining muscle health and function. Understanding the intricate mechanisms underlying muscle repair is of utmost importance for developing effective therapies to treat muscle injuries, degenerative disorders, and age-related muscle loss [1]. This review paper aims to provide an overview of recent advancements in the field of muscle regeneration, focusing on key cellular and molecular processes, therapeutic strategies, and emerging technologies. The field of muscle regeneration has witnessed remarkable progress in recent years, driven by a growing understanding of the intricate cellular and molecular mechanisms that govern this complex process [2]. Muscle tissue possesses a remarkable ability to repair and regenerate in response to injury, exercise, or disease, making it a fascinating area of research with significant implications for both clinical applications and our fundamental understanding of tissue biology [3].

Muscle regeneration is orchestrated by a dynamic interplay of various cell types, signaling pathways, and extracellular factors. Central to this process are satellite cells, which reside quiescently within the muscle tissue until activated by injury or stress. Upon activation, these satellite cells proliferate and undergo differentiation, ultimately contributing to the formation of new myofibers and the restoration of muscle function. This orchestrated sequence of events involves a delicate balance between various molecular cues, including growth factors, cytokines, and transcription factors, all of which play vital roles in coordinating the repair process [4]. Recent studies have illuminated the importance of the microenvironment surrounding muscle fibers, known as the niche, in influencing the behavior of satellite cells during regeneration. Interactions between satellite cells, extracellular matrix components, and immune cells within the niche contribute to the regulation of cell fate decisions and the overall success of the regenerative process. Disruptions in these interactions can lead to impaired regeneration and contribute to the pathogenesis of muscle-related disorders [5].

Cellular and molecular Processes

Muscle regeneration is primarily orchestrated by satellite cells, a population of musclespecific stem cells residing beneath the basal lamina of muscle fibers. Upon injury or stress, satellite cells are activated and undergo a process of proliferation, differentiation, and fusion to form new myofibers. Research has revealed a multitude of signaling pathways, including the Notch, Wnt, and transforming growth factor-beta (TGF-β) pathways, that regulate satellite cell behavior during muscle repair [6]. Additionally, interactions between satellite cells and the extracellular matrix, as well as immune cells, contribute to the orchestration of the regenerative process.

Therapeutic strategies

Recent advancements in muscle regeneration research have led to the development of promising therapeutic strategies. Cell-based therapies involving transplantation of satellite cells or engineered stem cells have shown potential in enhancing muscle regeneration and functional recovery. Moreover, the modulation of signaling pathways through small molecules, growth factors, and gene therapies holds great promise for promoting satellite cell activation and muscle repair. Biomaterial scaffolds, which provide structural support and deliver bioactive factors, have also emerged as innovative tools to enhance muscle regeneration in challenging clinical scenarios [7].

The field of muscle regeneration is being revolutionized by emerging technologies. Three-dimensional bioprinting, for instance, enables the precise fabrication of muscle constructs with tailored architectures, promoting better tissue integration upon transplantation. Advances in gene editing techniques, such as CRISPR-Cas9, offer the potential to correct genetic mutations underlying muscular dystrophies and other muscle disorders. Furthermore, the use of tissue-on-a-chip platforms allows researchers to study muscle physiology and drug responses in vitro, providing valuable insights into disease mechanisms and therapeutic interventions [8].

Challenges and Future Directions

While significant progress has been made, challenges in muscle regeneration research remain. Improving the long-term engraftment and functionality of transplanted cells, unraveling the complexities of satellite cell heterogeneity, and enhancing the vascularization of regenerated tissue are areas that warrant further investigation.

Additionally, translating promising findings from preclinical studies to clinical applications requires careful consideration of safety, scalability, and regulatory approvals [9].

In conclusion, muscle regeneration is a multifaceted process regulated by intricate cellular and molecular mechanisms. Recent advancements in understanding these processes have led to the development of innovative therapeutic strategies and technologies that hold promise for enhancing muscle repair and functional recovery. Continued collaborative efforts between researchers, clinicians, and bioengineers are essential to address the challenges and realize the full potential of regenerative approaches for treating muscle-related disorders.
