Autologous mesenchymal stem cells application in post-burn scars treatment: a preliminary study

Area of Science:

• Regenerative Medicine
• Stem Cell Therapy
• Dermatology

Background:

• Post-burn scars cause significant functional and aesthetic impairments.
• Scar formation mechanisms are complex and influenced by multiple factors.
• Adipose tissue is an increasingly preferred source for mesenchymal stem cells (MSCs) due to higher yield and comparable clinical outcomes to bone marrow.

Purpose of the Study:

• To evaluate the efficacy of autologous adipose tissue-derived MSCs in scar remodelling.
• To assess the versatility of MSC application across different scar types (atrophic, hypertrophic, keloids).
• To investigate MSCs' role in improving outcomes of surgical scar reconstructions.

Main Methods:

• Autologous adipose tissue-derived MSCs were applied to post-burn scars in 8 patients undergoing surgical reconstruction.
• Procedures included dermabrasion, scar excision, contracture correction, and local plasties, combined with lipografting or direct MSC application.
• Scars were assessed using the Vancouver Scar Scale (VSS) before surgery and 6 months post-treatment.

Main Results:

• The average VSS score decreased from 7.88 pre-treatment to 2.34 at 6 months post-treatment.
• Significant improvements were observed in scar appearance and function.
• The treatment demonstrated positive effects on scar remodelling across various scar types.

Conclusions:

• Autologous adipose tissue-derived MSCs show promise for enhancing scar remodelling after surgical reconstruction of post-burn scars.
• This regenerative approach offers a potentially effective strategy for improving both functional and aesthetic outcomes in burn scar management.
• Further research is warranted to fully elucidate the mechanisms and optimize the application of MSCs in scar therapy.
