BIO-ENGINEERING SOLUTIONS FOR MUSCULAR DYSTROPHY
- Gene Therapy:
- Gene Replacement: Gene therapy involves delivering functional copies of the defective gene responsible for muscular dystrophy into muscle cells. Viral vectors are often used to carry the corrected gene.
- CRISPR-Cas9: The CRISPR-Cas9 gene-editing system can correct mutations in the dystrophin gene, potentially restoring proper protein production.
- Cell Therapy and Regenerative Medicine:
- Stem Cell Transplantation: Stem cells, including mesenchymal stem cells and induced pluripotent stem cells (iPSCs), can regenerate damaged muscle tissue.
- Muscle Cell Engineering: Muscle cells can be engineered in the lab and transplanted into affected areas to promote muscle regeneration.
- Muscle Tissue Engineering:
- 3D Muscle Constructs: Engineers are working on creating 3D muscle tissue constructs in the lab using bioengineered scaffolds and muscle cells. These constructs could potentially be used for transplantation or drug testing.
- Exon Skipping:
- Exon skipping involves using synthetic molecules (oligonucleotides) to skip over specific exons in the dystrophin gene during protein production. This approach can lead to the production of a partially functional dystrophin protein
- Electrical Stimulation and Neuromuscular Interfaces:
- Neuromuscular Prosthetics: Electrodes and neural interfaces can stimulate muscles and restore muscle function in individuals with muscular dystrophy.
BIO-ENGINEERING SOLUTIONS FOR OSTEOPOROSIS
- Biomechanical Implants and Assistive Devices:
- Implants: Engineers are working on developing bioresorbable implants that can be placed in areas of weak bones to provide support during the healing process.
- Exoskeletons: Wearable exoskeletons can assist individuals with weakened muscles or bones maintain proper posture and mobility, reducing the risk of falls and fractures
- Bone Regeneration and Tissue Engineering:
- 3D-Printed Implants: 3D printing technology can be used to create custom implants that mimic the structure of bone tissue and encourage natural bone regeneration.
- Stem Cell Therapies: Stem cells can be manipulated to differentiate into bone-forming cells, promoting bone regeneration
- Diagnostic and Monitoring Tools:
- Advanced Imaging: High-resolution imaging techniques, such as micro-CT and MRI, can provide detailed information about bone structure and density, aiding in early diagnosis and monitoring.
- Wearable Sensors: Wearable devices can monitor gait, posture, and physical activity, providing insights into an individual’s movement patterns and fall risk.
- Biomechanical Research and Modeling:
- Computational Modeling: Advanced computer simulations can model bone mechanics and predict fracture risk, aiding treatment planning and decision-making
- Muscular dystrophy (MD) refers to a group of genetic disorders characterized by progressive weakening and degeneration of the muscles. These conditions result from mutations in genes responsible for the structure and function of muscles. Muscular dystrophy can affect people of all ages and is typically inherited, meaning it is passed down from parents to their children.
