Application and prospect of adipose stem cell transplantation in treating lymphedema.

ABSTRACT:

Background

Lymphedema is a chronic, debilitating and incurable disease that affects 0.13%-2% of the global population. Emerging evidence indicates that adipose-derived stem cells (ADSCs) might serve as suitable seed cells for lymphatic tissue engineering and lymphedema therapy.

Aim

To summarize applications of ADSCs for treating lymphedema in both animal studies and clinical trials.

Methods

A systematic search was performed on four databases - PubMed, Clinicaltrials.gov, the evidence-based Cochrane Library, and OVID - using the following search string: ("lymphedema" or "lymphoedema" or "lymphangiogenesis") and ("adipose-derived stem cells" or "adipose-derived stromal cells" or "adipose-derived regenerative cells"). A manual search was performed by skimming the references of relevant studies. Animal studies and clinical trials using adipose-derived cells for the treatment of any kind of lymphedema were included.

Results

A total of eight research articles published before November 2019 were included for this analysis. Five articles focused on animal studies and another three focused on clinical trials. ADSC transplantation therapy was demonstrated to be effective against lymphedema in all studies. The animal studies found that coadministration of ADSCs and controlled-release vascular endothelial growth factor-C or platelet-rich plasma could improve the effectiveness of ADSC therapy. Three sequential clinical trials were conducted on breast cancer-related lymphedema patients, and all showed favorable results.

Conclusion

ADSC-based therapy is a promising option for treating lymphedema. Large-scale, multicenter randomized controlled trials are needed to develop more effective and durable therapeutic strategies.
