Use of Lipotransfer in Scleroderma.
Aesthetic Surgery Journal 2017 July 2
Lipotransfer for soft tissue filling is a well-established plastic and aesthetic surgical technique. Elective fat grafting is considered a safe and well-tolerated procedure. Coleman and others have reported that fat grafting may have tissue regenerative properties and not only serve as a soft tissue filler. There have been reports from our group and others that it may improve fibrosis secondary to many different pathological aetiologies including scleroderma, burn injury, lichen sclerosis, graft vs host disease, and radiation. The mechanism of action remains unclear but has been postulated that is adipose derived stem cells (ADSCs) related. Lipoaspirate has been characterised and shown to contain several cell populations including fibroblasts, endothelial cells, and ADSCs. The ADSCs have shown to secrete angiogenic, immunodulatory, and antiapoptotic factors as well as proliferate and differentiate into different cell types similarly to other stem cell sources. We have shown that ADSCs are functionally different in scleroderma patients but despite this lipotransfer produces a significant reversal in the effects of fibrosis in these patients. The advantage of lipoaspirate containing a valuable source of regenerative properties, ease of access, isolation, and processing may serve a significant future role in the treatment of fibrotic conditions.
