摘要:

背景:体外扩增的自体脂肪来源干细胞具有多向分化的潜能,在组织工程和再生医学领域具有广阔的应用前景。
目的:观察自体脂肪来源干细胞移植受损人鼻黏膜组织的结构和功能变化。
方法:选取因物理或化学因素造成鼻黏膜损害的患者10例,其中6例黏膜瘢痕,4例黏膜破溃,抽取自体脂肪组织进行脂肪来源干细胞体外分离、培养、扩增,移植前进行质量安全性检测。6例患者在黏膜瘢痕基底部、4例患者在黏膜破溃处注射移植脂肪来源干细胞(1×107/cm2),共注射3次,每2次间隔15 d。末次注射移植后30,90,150 d分别行鼻腔容积、最小横断面积、黏膜纤毛清除功能测定,其中3例患者在移植前和移植后30 d,取0.1 cm×0.1 cm黏膜组织,进行苏木精-伊红染色、Masson三色染色、AB-PAS染色。
结果与结论:脂肪来源干细胞注射移植后,所有患者临床症状得到缓解。与移植前比较,脂肪来源干细胞注射移植后30,90,150 d鼻腔容积及鼻腔最小横断面积有所减少(P < 0.05),鼻黏膜纤毛清除功能有所改善,但差异无显著性意义(P > 0.05)。与移植前相比,脂肪来源干细胞移植30 d时3例患者鼻黏膜炎症明显减轻,胶原纤维排列整齐、沉积减少,杯状细胞分泌的黏蛋白增多。结果证明了体外扩增的脂肪来源干细胞可以重建鼻黏膜结构和恢复其功能。

Abstract:

BACKGROUND: The ex-vivo expanded autologous adipose-derived stem cells have the capability of multipotential differentiation and have a broad application prospect in the field of tissue engineering and regenerative medicine.
OBJECTIVE: To observe the nasal mucosal structural repair and functional reconstruction using ex-vivo expanded autologous adipose-derived stem cells.
METHODS: Ten patients with mucosal damage due to the physical or chemical factors were enrolled, including six cases of mucosal scar and four cases of mucosal ulceration. Autologous adipose tissue was extracted for in vitro isolation, culture and expansion of adipose-derived stem cells. Before transplantation, quality safety testing was done. All the patients were injected adipose-derived stem cells (1×107/cm2) at an interval of 15 days, totally for three times. Nasal volume, minimum cross-sectional area, and mucociliary clearance function were determined at 30, 90, 150 days after the final injection. Three of 10 patients were selected to take a 0.1 cm×0.1 cm mucosal tissue sample at 30 days before and after transplantation for hematoxylin-eosin staining, Masson trichrome staining, and AB-PAS staining.
RESULTS AND CONCLUSION: Clinical symptoms were alleviated in all patients undergoing transplantation of adipose-derived stem cells. Compared with the baseline data, the nasal volume and minimum cross-sectional area were both decreased at 30, 90, 150 days after transplantation (P < 0.05), and the mucociliary clearance function was improved but not significantly (P > 0.05). Compared with the baseline data, the inflammation of the nasal mucosa was significantly reduced, collagen fibers arranged neatly, the deposition was decreased, and mucin secreted from goblet cells was increased in the selected three patients at 30 days after cell transplantation. These findings indicate that ex-vivo expanded autologous adipose-derived stem cells can be used to reconstruct the nasal mucosal structure and its function.
