细胞生物学细胞生物学

背景情况:

脂肪组织移植对于再生手术至关重要,但面临诸如高吸收率 (50-90%) 和脂肪亡等挑战.
改善脂肪移植的存活和整合对于成功的临床结果至关重要.

研究的目的:

为了研究神经酸 (NA) 对脂肪生成和脂肪移植的影响.
阐明NA在脂肪移植中的作用的潜在分子机制.

主要方法:

在"体外"脂肪生成过程中对人间介质干细胞 (MSC) 的NA治疗,分析基因/蛋白质表达 (PPARγ,CEBPα,Akt/mTOR,Wnt信号传递).
在小鼠中与脂肪移植进行NA共同移植,然后进行组织学分析 (Oil Red O,H&E,对利平-1的免疫组织化学,CD31).

主要成果:

通过激活Akt/mTOR通路并抑制MSC中的Wnt信号,NA加速脂肪生成.
活体内*的NA治疗减少了脂肪移植的再吸收,增加了可活脂肪细胞的比例,并增强了血管化 (CD31+结构).

Mechanism of Angiogenesis

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
