Abstract:
In the last two decades, there has been a strong interest in searching for biological treatments for regeneration of injured growth plate cartilage and prevention of its bony repair. Various means have been tried, including implantation of chondrocytes, mesenchymal stem cell (MSC), together with exogenous growth factor and scaffolds, and gene therapy. However, with the lack of success with chondrocytes, more research has focussed on MSC-based treatments. In addition to circumvent limitations with MSC-based treatments (including cell harvest-associated morbidity, difficulties/time/cost involved in MSC isolation and ex vivo expansion, and potential disease transmission), mobilising endogenous MSCs to the growth plate injury site and enhancing in situ regeneration mechanisms would represent an alternative attractive approach. Further studies are required to investigate the potential particularly in large animal models or clinical setting of the ex vivo MSC approach and the feasibility of the endogenous MSC in situ approach in growth plate regeneration.
Insights
Researchers are exploring biological treatments for growth plate cartilage regeneration. Mesenchymal stem cell (MSC) therapies show promise but face challenges, leading to interest in mobilizing endogenous MSCs for in situ repair.
Area of Science:
- Orthopedics
- Regenerative Medicine
- Biotechnology
Background:
- Growth plate injuries can lead to long-term skeletal deformities.
- Current treatments focus on biological regeneration to prevent bony repair of cartilage.
- Mesenchymal stem cells (MSCs) are a key focus for regenerative therapies.
Purpose of the Study:
- To review biological treatment strategies for growth plate cartilage regeneration.
- To evaluate the potential and limitations of current approaches, particularly MSC-based therapies.
- To explore alternative strategies like endogenous MSC mobilization for in situ regeneration.
Main Methods:
- Review of existing literature on growth plate regeneration techniques.
- Analysis of chondrocyte implantation, MSC implantation (ex vivo), and gene therapy.
- Discussion of challenges associated with MSC isolation, expansion, and transplantation.
- Exploration of endogenous MSC mobilization for in situ repair.
Main Results:
- Chondrocyte implantation has shown limited success.
- Ex vivo MSC-based treatments are promising but have associated limitations.
- Mobilizing endogenous MSCs presents an attractive alternative for in situ regeneration.
- Further research is needed in large animal models and clinical settings.
Conclusions:
- Mesenchymal stem cell therapies offer potential for growth plate regeneration.
- Overcoming limitations of ex vivo MSC treatments is crucial.
- Investigating endogenous MSC mobilization for in situ repair warrants further study.
- Clinical translation requires validation in large animal models and human trials.
