文题释义:
成体干细胞:
在机体的各种组织器官中均存在成体干细胞,是已分化组织中的未分化细胞,通过按一定程序的自我更新和形成特异组织类型细胞来维持组织细胞功能的稳态。正常情况下多数处于休眠状态,其所处微环境的改变可激活休眠的成体干细胞参与组织的更新和修复。文章阐述的成体干细胞主要是指小鼠腹白线脂肪组织成体干细胞。
腹白线:Rick通过对人和19种动物腹白线的观察,最早报道了前腹壁腱膜纤维在腹白线的交织情况。他认为腹白线是由腹前正中线上两侧腹肌腱膜纤维交织而成的腱性结构,起于剑突软骨终止于耻骨联合上缘,而作者通过实验首次观察到小鼠腹白线由脂肪组织构成。在腹针疗法中,腹白线是任脉在腹部的体表标志,确定了任脉在腹部取穴的标准。
任脉:在经络理论中,分正经和奇经两大类。正经有12条,奇经有8条,称奇经八脉。任脉属奇经八脉,行循于胸腹部前正中,能总任一身之阴经,具有调节气机的功能,还有“妊养”的功能,与生殖有关,其起于小腹内,向下行于会阴,再向上行于腹白线,向上至胸前正中线,至咽喉上行口目。

 

摘要
背景:
干细胞与经络的关系目前还停留在理论探讨阶段,亟需通过实验进行科学研究。  
目的:通过实验观察小鼠腹白线脂肪组织Sca-1+成体干细胞的分布情况,为进一步探讨干细胞与任脉的关系提供实验基础。
方法:选取Balb/c小鼠,通过体视显微镜、苏木精-伊红染色观察小鼠皮下胸部前正中线任脉循行部位组织形态特点。以任脉在腹部的体表标志——腹白线为研究对象,通过体视显微镜、苏木精-伊红染色、油红O染色、Masson染色观察小鼠腹白线组织形态特点;通过免疫组织化学染色、多层切片观察小鼠腹白线脂肪组织Sca-1+成体干细胞分布情况。
结果与结论:①首次观察到脂肪组织呈条带状分布于小鼠皮下前正中线任脉循行部位;②首次观察到小鼠腹白线由脂肪组织构成;③首次观察到Sca-1+成体干细胞沿小鼠任脉在腹部的体表标志——腹白线分布;④该实验只对任脉腹白线段Sca-1+成体干细胞进行了观察,是在一个小范围的尝试,但这一尝试有可能为探讨任脉功能与干细胞功能提供实验基础与思路。

Abstract:

BACKGROUND: The interaction between stem cells and meridians and collaterals is still in the stage of theoretical research, and it is urgent to conduct relevant scientific experiments.
OBJECTIVE: To observe the distributions of Sca-1+ adult stem cells in the fat tissues of murine linea alba, providing an experimental basis for further studying the interaction of stem cells with meridians and collateral channels. 
METHODS: Balb/c mice were selected to observe the morphological characteristics of any Ren-meridian circulation regions along the anterior midline of the subcutaneous chest of the mice through stereomicroscopy and hematoxylin-eosin staining. Linea alba, the abdomen landmark of Ren-meridian, was selected as the objective of our study. Morphologies of tissues from linea alba were observed by stereomicroscope, hematoxylin-eosin staining, oil red O staining and Masson staining. Distribution of Sca-1+ adult stem cells from fat tissues in the linea alba was observed by immunohistochemical staining and multiple slices. 
RESULTS AND CONCLUSION: (1) In the study, we firstly observed that the fat tissues presented with band-like distribution in Ren-meridian circulation regions along the anterior midline of the subcutaneous chest of mice. (2) We firstly found that murine linea alba was made of fat tissues. (3) We firstly observed that Sca-1+ adult stem cells were distributed along the linea alba, the abdomen landmark of Ren-meridian. The present study preliminarily investigated the Sca-1+ adult stem cells in the linea alba part of Ren-meridian. This attempt may provide an experimental basis and idea for the exploration of functions of stem cells and Ren-meridian.
