概括
在结肠的管状腺瘤 (TA) 中发现了间隔的非失塑性隐藏体 (INDC). 这些发现表明,INDC是TA发展的组成部分,并支持结直肠组织的野外癌症.
科学领域:
- 胃肠病学 胃肠病学
- 在瘤学瘤学.
- 细胞生物学 细胞生物学
背景情况:
- 管状腺瘤 (TA) 是一种由异形,管状密室特征的瘤多.
- 在TA的下面和边缘观察到非可塑性隐藏体.
- 这项研究侧重于在TA内的失塑性隐藏体中发现的间接非失塑性隐藏体 (INDC).
研究的目的:
- 调查结肠直肠管状腺瘤 (TA) 中的间隔性非可塑性隐藏体 (INDC) 的存在和特征.
- 在TA中分析与INDC相关的分支模式和光发育不良.
- 了解INDC在TA开发和结直肠领域癌症化方面所扮演的角色.
主要方法:
- 在139个管状腺瘤 (TA) 的队列中,系统地记录了INDC的发生.
- 我们对INDC的分支模式进行了分类 (不对称,单一,对称).
- 在表现出INDC的TA中评估了光线发育不良的存在.
主要成果:
- 在研究的139种管状腺瘤 (TA) 中,31%发现了间歇性非扩散性隐藏体 (INDC).
- 大多数INDC被发现是不对称的分支模式 (INDCAB,58%),其次是单个密码 (INDSNB,35%) 和对称分支 (INDCSB,7%).
- 在具有INDC的TA患者中,观察到53%的发光性发育不良,主要在具有INDCAB (37%) 和INDSNB (16%) 的患者中,但在INDCSB中没有发光性发育不良.
结论:
- 在TA中存在INDC,特别是在不对称的分支模式中,这是一个与正常结直肠粘膜形成鲜明对比的重要发现.
- INDC可能是TA的组成部分,可能代表异常密码生成的残余物.
- 这些观察结果支持了人类结直肠中现场癌变的概念,在人类结直肠中,广泛的粘膜变化先于瘤的发展.

Renewal of Intestinal Stem Cells
2.5K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Histology of the Small Intestine
561
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

Tumor Progression
6.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Inflammatory Bowel Disease II: Crohn's Disease
194
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
