Wound therapy by marrow mesenchymal cell transplantation

Area of Science:

• Regenerative Medicine
• Tissue Engineering
• Dermatology

Background:

• Marrow mesenchymal cells possess stem cell properties valuable for regenerative medicine.
• Clinical applications of marrow mesenchymal cells have been limited.
• A novel wound treatment utilizes improved marrow mesenchymal cell culture and artificial skin material.

Observation:

• A composite graft of cultured marrow mesenchymal cells within artificial dermis was created.
• Subcutaneous implantation in mice demonstrated tissue regeneration.
• The technique was applied to 20 patients with intractable skin wounds.

Findings:

• Eighteen of 20 patients experienced significant wound healing.
• Autologous marrow mesenchymal cell transplantation proved therapeutically effective.
• The procedure involved minimally invasive bone marrow aspiration.

Implications:

• This marrow mesenchymal cell/artificial dermis composite graft enables skin regeneration.
• The technique is practical and less invasive than traditional skin grafting.
• Further clinical applications in regenerative medicine are suggested.
