概括

一个罕见的,快速生长的子宫内膜多与非典型的树皮细胞显示了一种新的JAK2::NFIB基因融合. 这一发现挑战了这种多的传统良性分类,并要求进一步调查它们的生物性质.

科学领域:

妇科病理学妇科病理学
在瘤学瘤学.
分子病理学分子病理学

背景情况:

在妇科多中非典型的树突细胞不常见,通常在绝经前/绝经后患者中发现,并被认为是良性的.
这些病变在阴道,子宫和子宫内膜中观察到,历史上没有出现复发或恶性病变.

研究的目的:

报告一个罕见的快速扩大的子宫内膜聚与非典型的树皮细胞的病例.
为了研究这种不寻常的子宫内膜多的分子基础.

主要方法:

带有异常 stromal 细胞的子宫内膜多的组织病理学检查.
RNA测序分析以确定遗传变化.
对患者进行临床随访.

主要成果:

一名76岁的妇女因快速生长的子宫内膜多而出现阴道出血.
组织学揭示了非典型的 stromal 细胞和血管通道;在良性多和腺癌之间进行了诊断辩论.
在六个月内,多胞体迅速复发,导致子宫切除.
RNA测序检测出了多体中一种新的JAK2::NFIB基因融合.

结论:

迅速复发和JAK2::NFIB基因融合的存在挑战了具有异常 stromal 细胞的子宫内膜息肉的良性性质.
需要进一步的研究,以了解这些基因融合在子宫内膜聚合物的病变和临床影响.

Multipotency and Niche of Bulge Stem Cell

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
