概括
在骨髓 stromal 细胞 (BMSCs) 中抑制 SP7 基因减少了软骨修复标记物和缩. 然而,这种方法也损害了冠状体的分化,突出显示了组织工程的挑战.
科学领域:
- 生物材料科学 生物材料科学
- 干细胞生物学 干细胞生物学
- 组织工程是组织工程.
背景情况:
- 骨髓 stromal 细胞 (BMSCs) 对于软骨修复至关重要,但往往会发生过多变的分化.
- 转化生长因子β1 (TGF-β1) 诱导BMSC分化,上调SP7,这是超的一个关键因素.
- 即使在TGF-β1退出后,SP7仍然升高,这对受控的冠状体生成构成了挑战.
研究的目的:
- 调查SP7在BMSC分化中的作用,以修复软骨.
- 为了评估是否沉默SP7可以减轻高差异化,而不会损害chondrogenesis.
主要方法:
- 稳定转导的BMSCs与shRNA沉默SP7表达.
- 评估BMSC差异化在chondrogenic,骨质原和脂肪原培养.
- 分析微组织大小,甘氨酸甘氨酸生产和基因表达.
主要成果:
- SP7静音降低了高和体分的分化,导致更小的微组织和更少的葡萄糖氨基酸糖.
- 通过SP7沉默,原体和高缩标记物的基因表达减少了.
- SP7静音还影响了骨质和脂肪的分化,减少了矿化和脂质的形成.
结论:
- SP7在BMSCs的三线分化中发挥着重要作用.
- 沉默SP7会减轻BMSC缩,但也会损害体生成,表明它无法解这些过程.
- 仅仅针对SP7是不够的,以克服在软骨组织工程中抑制缩的挑战,同时促进软骨生成的挑战.

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...
