概括

研究人员在管状腺瘤 (TA) 中发现了一种新的组织学特征,称为带侧芽 (DCLB) 的失塑性隐藏体. 这一发现增强了对结直肠腺瘤发展和特征的理解.

科学领域:

胃肠病学胃肠病学
病理学病理学病理学
在瘤学瘤学.

背景情况:

管状腺瘤 (TA) 是最常见的结直肠腺瘤类型.
目前对TA的定义缺乏针对失生性密室表型的具体标准.
了解腺瘤异质性对于结直肠癌研究至关重要.

研究的目的:

在TA中报告一种新型的密室表型,其特征是带有横向芽生长 (DCLB) 的失塑密室.
调查TA中DCLB的流行率和特征.
探索DCLB和TA特征之间的关系.

主要方法:

对309个管状腺瘤进行了组织病理学分析.
识别和量化带有横向芽的失生性隐藏体 (DCLB).
对DCLB存在与TA大小,发育不良程度,年龄,性别和位置的相关性分析.

主要成果:

在25.9%的TA中发现了一种新的表型,DCLB.
DCLB的存在独立于TA大小和发育不良的程度.
患者的年龄,性别或腺瘤位置对DCLB发生没有影响.

结论:

一种新的组织学表型,DCLB,是某些TA的组成部分.
在TA中发现了多种多样化的失塑性密室表型,这需要进一步的研究.
了解这些表型可能有助于了解为什么TA很少侵入宿主.

Renewal of Intestinal Stem Cells

Renewal of Intestinal Stem Cells

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...
