Adipose-derived stem cells (ASCs) transplanted along with autologous adipose tissue may improve fat graft survival; however, the efficacy of ASCs has been diluted by low vascularization. This study was designed to test the hypothesis that basic fibroblast growth factor (bFGF) may improve the effects of ASCs because it owns the property to boost angiogenesis. In the present study, human fat tissues were mixed with ASCs, ASCs plus 100 U bFGF, or medium as the control and then injected subcutaneously into immunologically compromised nude mice for 12 weeks. Our findings demonstrated that mixture with the ASCs significantly increased the weight and volume of the fat grafts compared to control grafts, and histological analysis revealed that both ASCs and ASCs plus bFGF grafts consisted predominantly of adipose tissue and had significantly less fibrosis but greater microvascular density compared with control and also grafts mixed with ASCs had a high expression of angiogenic factors. More importantly, the bFGF treated fat grafts shown elevate in survival, vascularization, and angiogenic factors expression when compared with the grafts that received ASCs alone. These results indicated that bFGF together with ASCs can enhance the efficacy of autologous fat transplantation and increase blood vessel generation involved in the benefits from bFGF.

Abstract Background Autologous fat transfer is a popular option for soft tissue augmentation, but has a low survival rate. So, enriching the transplanted fat with stem cells (cell assisted lipotransfer) or oral administration of alpha-lipoic acid (ALA) before and after graft injection, were thought to increase the survival rate of the transplanted fat. Aim of Study Is to compare between cell-assisted lipotransfer (CAL) and ALA therapy in improvement of fat graft survival. Materials and Methods Thirty adult female albino rats were used and divided into three groups. Group I: the control group. Group II: CAL group received autologous fat mixed with adipose derived stem cells (ASCs). Group III: ALA group in which animals received oral ALA four days before fat transplantation and continued throughout experiment. Fat grafts were collected from the sites of injection after twenty-eight days. Histological and immune histochemical studies were performed. Statistical analysis was also done. Results Histological evaluation of the fat grafts from animals of control group revealed atrophy and death of adipocytes with formation of fat cysts. Severe inflammatory infiltration with giant cells formation and fibrosis were detected. Significant decrease of VEGF reaction was seen. In CAL group significant increase in number of intact adipocytes together with decrease in inflammation and fibrosis occurred. Moreover, significant increase in VEGF reaction was observed. In ALA group, significant decrease in number of intact adipocytes and VEGF reaction was detected compared with CAL group. Also, significant increase in inflammatory infiltration and fibrosis were detected compared to CAL group. Conclusions Both ASCs and ALA showed improvement in all histological parameters compared with control group. However, enrichment of fat with ASCs showed the best results.

Conventional breast cancer extirpation involves resection of parts of or the whole gland, resulting in asymmetry and disfiguration. Given the unsatisfactory aesthetic outcomes, patients often desire postmastectomy reconstructive procedures. Autologous fat grafting has been proposed for reconstructive purposes for decades to restore form and anatomy after mastectomy. Fat has the inherent advantage of being autologous tissue and the most natural-appearing filler, but given its inconsistent engraftment and retention rates, it lacks reliability. Implementation of autologous fat grafts with cellular adjuncts, such as multipotent adipose-derived stem cells (ADSCs), has shown promising results. However, it is pertinent and critical to question whether these cells could promote any residual tumor cells to proliferate, differentiate, or metastasize or even inducede novocarcinogenesis. Thus far, preclinical and clinical study findings are discordant. A trend towards potential promotion of both breast cancer growth and invasion by ADSCs found in basic science studies was indeed not confirmed in clinical trials. Whether experimental findings eventually correlate with or will be predictive of clinical outcomes remains unclear. Herein, we aimed to concisely review current experimental findings on the interaction of mesenchymal stem cells and breast cancer, mainly focusing on ADSCs as a promising tool for regenerative medicine, and discuss the implications in clinical translation.
