Aquapuncture Using Stem Cell Therapy to Treat Mdx Mice

Area of Science:

• Regenerative Medicine
• Stem Cell Therapy
• Musculoskeletal Disorders

Background:

• Duchenne muscular dystrophy (DMD) is a genetic disorder causing progressive muscle degeneration due to dystrophin deficiency.
• Mesenchymal stem cell (MSC) therapy is explored as a potential treatment for DMD.
• Stem cells from human exfoliated deciduous teeth (SHED) offer a unique source of MSCs.

Purpose of the Study:

• To evaluate the efficacy of SHED cell therapy, delivered via acupoint injection (aquapuncture), in mitigating muscle degeneration in mdx mice, an animal model for DMD.
• To assess the impact of SHED therapy, alone and in combination with aquapuncture, on muscle strength, serum creatine kinase levels, and muscle histology in mdx mice.

Main Methods:

• Twenty-two mdx mice received three SHED injections at 21-day intervals.
• Muscle strength was assessed using a wire test.
• Serum creatine phosphokinase (CPK) levels were measured.
• Histological and immunohistochemical analyses of cranial tibial muscles were performed post-euthanasia.

Main Results:

• SHED-treated groups showed significant improvements in muscle strength and reduced CPK levels compared to controls.
• Histological analysis revealed minimized muscle degeneration in treated animals.
• A slight increase in dystrophin expression was observed in the cranial tibial muscles of mice treated with SHED combined with aquapuncture.

Conclusions:

• SHED cell therapy, particularly when combined with aquapuncture, demonstrates therapeutic potential in reducing muscle degeneration and improving muscle function in a mouse model of DMD.
• This approach offers a promising alternative strategy for managing Duchenne muscular dystrophy.
