FOR SOME KEY WORDS:
thymic epithelial cells (TECs)胸腺上皮细胞群
major medullary TEC (mTEC I–IV)主要髓质胸腺上皮细胞
Cortical thymic epithelial cells (cTEC)皮质胸腺上皮细胞
for the first part:
The medulla epithelial compartment has diverse molecular functions:
part II:Genetic and epigenetic characterization of TEC subsets
四大以及五大TEC亚细胞群基于基因以及表观的分类
part III:
Characterization of AIRE-dependent mTEC subsets
AIRE marker dependent cell type is mTEC-II,which with the highest mean expression
part IV:
mTEC IV, a new TEC population with tuft-cell characteristics,mTEC四型是一种有绒簇的新TEC细胞群
通过组织切片染色以及流式细胞分析技术,用不同的marker将TEC IV细胞分选出来。并且对基因型以及野生型都有相应的流式对比图。

本文章指出,虽然胸腺对于Tcell 的发育起着至关重要的作用但是髓质的上皮细胞却在单细胞测序层面显示出了高超的分化以及异质性,呈递不同的抗原以及表现出气味受体,从而形成髓质微环境,这些发现表明,髓质环境有分隔性,其中小而高度专一性高的分化的特定上皮细胞亚群具有在胸腺功能形成中的至关重要而非冗余的作用。
part I:
Tuft-like cells are closely associated with cornified bodies in the thymic medulla
part II :Thymic DCLK1bright cells are a novel subset of tuft cells
part III:
Aire is expressed by some thymic tuft cells but is not required for their development
part IV:
Thymic tuft cells promote an IL-4-enriched medullary microenvironment and enforce tolerance.
