Abstract
Fibrocytes are unique bone marrow-derived cells with great potential in wound healing. Hence, the aim of this study was to determine the safety and efficacy of the applied circulating fibrocytes in the treatment of non healing diabetic foot ulcers. Peripheral blood mononuclear cells were isolated by centrifugation through Ficoll-Paque method. After 3?days, the non adherent cells were removed by a single, gentle aspiration. Adherent cells were cultured in the same medium for 10?days. The cells were characterised using mouse anti-human-CD45-fluorescein isothiocyanate (FITC) and mouse anti-human-collagen I, and also characterised by immunofluorescence microscopy using the above mentioned antibodies. Sterility measures were applied for clinical evaluation. Based on the literature review, cell transplantation generally requires at least 3?×?106 cells regarding efficacy measures. As fibrocytes are non proliferating cells, 350?ml patient's blood is required to prepare patient-specific serum before cell isolation and culture, and 85?ml patient's blood is needed for cell isolation and differentiation on cell transplantation applications. In our survey, no diabetic patient was inclined to be donor of such blood volume, mainly because of their pre-assumption that they are anaemic. It is concluded that fibrocytes do not seem to be

- •both males and females, age 40-70 years old, with wounds area ranging from 2 to 6 cm2, (exposed bones may also be included if other criteria are filled), healing refractory despite comprehensive treatment for at least 6 weeks and Grade II, III and IV of Wagner's classification system (wound will be debrided), Wounds in the Gangrene stage are included if they are wet, but suppurative wounds may be enrolled after complete treatment of the infection. Mostly wounds with the cavity formation will be preferred to enrolled, as in the cases after debridement with a remained cavity unfilled with healed tissues, compliant, alert enough to understand the process of the research project which are high risk for amputation and are not indicated for vascular surgery or are unable to endure surgery are considered to be included.
