[Interests and potentials of adipose tissue in scleroderma].
La Revue de Médecine Interne 2013 December
Systemic sclerosis is a disorder involving the connective tissue, arterioles and microvessels. It is characterized by skin and visceral fibrosis and ischemic phenomena. Currently, therapy is limited and no antifibrotic treatment has proven its efficacy. Beyond some severe organ lesions (pulmonary arterial hypertension, pulmonary fibrosis, scleroderma renal crisis), which only concern a minority of patients, the skin sclerosis of hands and face and the vasculopathy lead to physical and psychological disability in most patients. Thus, functional improvement of hand motion and face represents a priority for patient therapy. Due to its easy obtention by fat lipopaspirate and adipocytes survival, re injection of adipose tissue is a common therapy used in plastic surgery for its voluming effect. Identification and characterization of the adipose tissue-derived stroma vascular fraction, mainly including mesenchymal stem cells, have revolutionized the science showing that adipose tissue is a valuable source of multipotent stem cells, able to migrate to site of injury and to differentiate according to the receiver tissue's needs. Due to easy harvest by liposuction, its abundance in mesenchymal cells far higher that the bone marrow, and stroma vascular fraction's ability to differentiate and secrete growth angiogenic and antiapoptotic factors, the use of adipose tissue is becoming more attractive in regenerative medicine. We here present the interest of adipose tissue use in the treatment of the hands and face in scleroderma.
