概括

乳腺腺瘤上皮细胞中的异性粗颗粒类似于生殖细胞颗粒,可能表明转化. 这些发现并不特定于细胞分化,需要进行全面分析才能准确诊断.

科学领域:

病理学病理学病理学
细胞生物学细胞生物学
历史学历史学历史学

背景情况:

乳腺腺增生是一种良性乳腺疾病,其特征是腺体扩散.
在上皮细胞中存在着埃索诺菲尔粗颗粒是一种观察到的,但尚未完全理解的现象.
将这些颗粒与病理标记区分开来,对于准确诊断至关重要.

研究的目的:

为了研究乳腺腺瘤上皮细胞中异氨基粗颗粒的形态和免疫类型特征.
为了确定这些颗粒的临床病理学意义.
为了区分这些发现与恶性疾病,如状细胞癌.

主要方法:

收集了64例乳腺腺瘤,其中含有eosinophilic粗颗粒.
进行了血素和欧 (HE) 染色,用于形态分析.
对各种标记物 (lyszyme,EMA,S-100等) 进行了免疫组织化学染色. 和体化学染色 (PAS,粘胺,AB).

主要成果:

在细胞质中发现了扩散分布在细胞质中的eosinophilic粗颗粒,大小不同,并表现出折射性.
免疫组织化学检测显示,对lyszyme,α-抗素,α-抗基素,cathepsin D,EMA和S-100的阳性反应.
粉酶消化前后的PAS染色呈阳性;其他标记物呈阴性,表明具有非特异性.

结论:

这些颗粒类似于生菌颗粒,表明乳腺上皮细胞的非特异性转化.
对lyszyme和antichymotrypsin的阳性染色并不意味着特定的细胞分化.
诊断细胞癌需要对形态学和免疫组织化学进行全面分析,而不仅仅是这些颗粒.

Classification of Leukocytes

Classification of Leukocytes

Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
