概括

这项研究发现,当与甲 (Dex) 结合时,L(+) - 氨酸 (Arg) 在大鼠骨髓细胞 (rBMCs) 中显著增强骨质生成. 氨基酸L(+) -lysine (Lys) 对这个过程没有显著影响.

科学领域:

生物化学生物化学
细胞生物学细胞生物学
再生医学是一种再生医学.

背景情况:

牙纤维组织是牙再生的潜在来源,但其去除会造成缺陷.
牙纸中介质干细胞 (MSC) 的增殖和分化速度很慢.
需要新的加速器来增强MSC的增殖和分化在体外.

研究的目的:

研究L(+) - 氨酸 (Arg) 和L(+) - 氨酸 (Lys) 对MSC亚种中矿化结节的形成的影响.
在实验室中识别促进骨质生成和牙生成的生物活性因素.

主要方法:

鼠骨髓细胞 (rBMCs) 在补充了甲基 (Dex) 和Arg或Lys的介质中培养.
矿化结节聚合物被形成并脱.
测量离子 (Ca2+) 水平作为骨质或牙发生的指标.

主要成果:

补充剂 (1.150 mmol) 在rBMCs中显著增强了Dex诱导的骨质生成,由较高的Ca2+水平表明.
补充剂 (68.4或136.8毫摩尔) 和较低度的Arg (0.575毫摩尔) 对Ca2+水平没有显著影响.
与Arg结合使用的Dex积极促进了MSCs的骨质生成活性.

结论:

在甲的存在下,L(+) - 氨酸作为一种辅助因子,显著促进MSC的骨质性活性.
进一步的研究可能会探索Arg作为骨和牙形成再生疗法的关键组成部分.

Mesenchymal Stem Cells

Mesenchymal Stem Cells

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...

Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
