目的:探讨脂肪来源干细胞复合不同生物支架在裸鼠皮下的促血管化作用。方法:根据所选支架的不同,将实验分为4组,A组为脂肪颗粒,B组为透明质酸钠,C组为Ⅰ型胶原支架,分别按体积比1:1与25×106 mL-1的脂肪来源干细胞混合,D组为单纯脂肪来源干细胞,将4组试剂注射到12只裸鼠皮下构建软组织,每只裸鼠各注射4个点,3个月后获取相应标本,测定湿质量、存活率、微血管密度。结果:4组间湿质量、存活率、微血管密度比较,差异均有统计学意义(F=47.523、48.425和47.619,P均<0.05),且A、B、C组湿质量、存活率、微血管密度均高于D组(P均<0.05)。结论:脂肪来源干细胞复合生物支架可加速软组织血管化,且效果优于单纯脂肪来源干细胞。
目的:探討脂肪來源榦細胞複閤不同生物支架在裸鼠皮下的促血管化作用。方法:根據所選支架的不同,將實驗分為4組,A組為脂肪顆粒,B組為透明質痠鈉,C組為Ⅰ型膠原支架,分彆按體積比1:1與25×106 mL-1的脂肪來源榦細胞混閤,D組為單純脂肪來源榦細胞,將4組試劑註射到12隻裸鼠皮下構建軟組織,每隻裸鼠各註射4箇點,3箇月後穫取相應標本,測定濕質量、存活率、微血管密度。結果:4組間濕質量、存活率、微血管密度比較,差異均有統計學意義(F=47.523、48.425和47.619,P均<0.05),且A、B、C組濕質量、存活率、微血管密度均高于D組(P均<0.05)。結論:脂肪來源榦細胞複閤生物支架可加速軟組織血管化,且效果優于單純脂肪來源榦細胞。

Aim:To discuss the affection of promoting neovascularization of adipose tissue derived stem cells (ADSCs) compounding with different cellular scaffold in nude mice subcutaneous stratum .Methods:The experiment was divided into four groups depending on the selected scaffold .Group A,B and C were given fat particles, sodium hyaluronate, typeⅠcol-lagen,respectively, mixed with ADSCs at 25 ×106 mL-1 .Group D was given pure ADSCs .Four reagents were injected ran-domly into subcutaneous stratum of 12 nude mice to build soft tissue .Each nude muse was injected 4 points.The appropri-ate specimens were obtained three months later and wet weight , survival rate and microvessel density were detected .Re-sults:The differences were statistically significant regarding the wet weight , survival rate , microvessel density among the four groups(F=47.523,48.425,47.619,P<0.05).The wet weight, survival rate, and microvessel density of group A ,B and C were higher than those of group D (P<0.05).Conclusion: ADSCs compounding with cellular scaffold could pro-mote neovascularization in subcutaneous stratum ,and is better than pure ADSCs .
