概括

干细胞标记物NANOG和SOX2显示出用于分类宫皮状内皮病变 (SILs) 的诊断潜力. 这些标记物可以区分低级SIL (LSIL) 和正常组织和高级SIL (HSIL),SOX2区分HSIL/CIN 2和HSIL/CIN 3.

科学领域:

妇科病理学的病理学.
分子诊断学分子诊断学
癌症生物标志物癌症生物标志物

背景情况:

子宫状内皮病变 (SILs) 和子宫内皮瘤 (CIN) 需要准确的分类来进行有效的管理.
当前的诊断方法在区分不同级别的SIL/CIN时可能存在局限性.

研究的目的:

评估干细胞标记物NANOG和SOX2在SIL/CIN分类中的诊断效用.
评估NANOG和SOX2是否可以作为差异化损伤等级的生物标志物.

主要方法:

在40个宫组织样本中对NANOG和SOX2表达的免疫组织化学分析 (非失塑性,LSIL,HSIL/CIN 2,HSIL/CIN 3,CSCC).
使用染色强度 (SI) 乘以阳性细胞的百分比 (P) 和染色厚度 (T) 来量化标记物表达的量化.
损伤等级和相邻的正常组织之间的标记物表达的比较;HPV基因型和p16/Ki-67染色也进行了.

主要成果:

NANOG和SOX2表达水平逐渐从正常上皮细胞通过LSIL和HSIL增加到宫平细胞癌 (CSCC).
与对照组相比,LSIL的NANOG和SOX2表达显著高于对照组,表达低于HSIL.
与HSIL/CIN 2相比,HSIL/CIN 3中的SOX2表达显著高于HSIL/CIN 2.

结论:

与p16.不同的是,NANOG和SOX2显示了区分LSIL与非扩张性皮表皮的潜力.
这些标记物可以作为替代生物标记物来区分LSIL和HSIL.
SOX2可能有助于区分HSIL/CIN 2和HSIL/CIN 3,因此需要对更大的队列进行进一步调查.

关键词:

这是一个NANOGNANOG.这就是SOX2的含量.癌症干细胞是一种癌症干细胞.宫癌:子宫癌是一种癌症.宫内皮质瘤是什么状内皮层病变的发生.

Somatic to iPS Cell Reprogramming

Somatic to iPS Cell Reprogramming

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Induced Pluripotent Stem Cells

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Stem Cell Niche

Stem Cell Niche

The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
