摘要
Abstract
BACKGROUND:Revascularization mechanism is the decisive factor for the successful construction of tissue-engineered adipose tissue. <br> OBJECTIVE:To observe the difference of in vivo adipogenic efficacy of adipose-derived stem cel s and col agen protein scaffold encapsulated in three muscular fasciae. <br> METHODS:The rabbit right vascularized latissimus dorsi muscular fasciae was separated and encapsulated with type Ⅰ col agen protein and adipogenic differentiated adipose-derived stem cel s complexes as the differentiation group with axial pattern blood vessel pedicle. The rabbit left vascularized latissimus dorsi muscular fasciae was separated and encapsulated with type Ⅰ col agen protein and undifferentiated adipose-derived stem cel s complexes as the undifferentiation group with axial pattern blood vessel pedicle. The rabbit gluteus maximus muscular fasciae without specific vascular pedicle was separated and encapsulated with type Ⅰ col agen protein and undifferentiated adipose-derived stem cel s complexes as the control group. <br> RESULTS AND CONCLUSION:Eight weeks after transplantation, hematoxylin-eosin staining and immunohistochemical staining showed that there was new adipose tissue formation in al groups. The mean humid weight of the neonatal fat tissue and the microvessel density in the differentiation group was higher than those in the undifferentiation group and the control group (P<0.01, P<0.05). It indicated that the vascularized tissue-engineered adipose was successful y established via adipose-derived stem cel s-attached scaffolds encapsulated in muscular fasciae with axial pattern blood vessel pedicle with good in vivo adipogenic efficiency and strong ability to promote angiogenesis.关键词
