An overview of stem cells and cell products involved in trauma injury

Trauma injuries represent a significant public health burden worldwide, often leading to long-term disability and reduced quality of life. This review provides a comprehensive overview of the therapeutic potential of stem cells and cell products for traumatic injuries. The extraordinary characteristics of stem cells, such as self-renewal and transdifferentiation, make them definitive candidates for tissue regeneration. Mesenchymal stem cells (MSCs), neural stem cells (NSCs), and hematopoietic stem cells (HSCs) have been tested in preclinical studies for treating distinct traumatic injuries. Stem cell mechanisms of action are addressed through paracrine signaling, immunomodulation, differentiation, and neuroprotection. Cell products such as conditioned media, exosomes, and secretomes offer cell-free resources, thereby avoiding the risks of live cell transplantation. Clinical trials have reported many effective outcomes; however, variability exists across trauma types. Some challenges include tumorigenicity, standardized protocols, and regulatory issues. Collaboration and interdisciplinary research are being conducted to harness stem cells and products for trauma treatment. This emerging field is promising for improving patient recovery and quality of life after traumatic injuries.
