germ layer

germ layer：/dʒɜːrm/ layer/leɪ/

基本翻译：胚层。

速记技巧：germ（细菌）＋layer（层）→胚层，可以谐音联想为“盖儿（germ）来（layer）胚层”。

Germline layer是细胞生物学中的术语，指的是一种细胞类型，通常存在于动物胚胎的原始组织中。它的英文词源可以追溯到拉丁语“germen”和“linea”，意为“种子”和“线”，表示这种细胞类型是从受精卵发育而来的。

Germline layer的变化形式主要是复数形式“germline layers”或简写为“germ layers”。

相关单词有：

1. “cell lineage”意为细胞谱系，指的是一个细胞或一群细胞的发育过程。

2. “embryonic development”意为胚胎发育，指的是从受精卵到出生前的生长过程。

3. “germ cell”意为生殖细胞，指的是能够繁殖后代的细胞，如精子和卵子。

4. “germinal layer”意为原始层，指的是胚胎早期存在的一种细胞层，其中包含各种类型的细胞前体。

5. “neural crest”意为神经突起，是一种在胚胎发育过程中形成的细胞群，能够分化为神经元和胶质细胞。

6. “mesoderm”意为中胚层，是动物胚胎的一种重要组织，包含许多不同类型的细胞，如肌肉、骨骼和内脏器官的原始细胞。

7. “epithelium”意为上皮层，指的是覆盖在身体表面或封闭腔内的细胞层，如皮肤和肠粘膜。

8. “progenitor cell”意为祖细胞，指的是能够分化为其他细胞的细胞，在胚胎发育和组织再生中扮演重要角色。

9. “stem cell”意为干细胞，指的是能够自我更新并分化为多种类型细胞的细胞，在医学上具有广泛的应用前景。

10. “fate”意为命运，指的是一个细胞或一个生物体的未来发展路径。与germline layer相关的命运包括分化为特定类型的细胞或最终成为生物体的某个部分。

The Germ Layer: An Essential Part of Our Body"s Development and Functioning

The germ layer of the human body is a crucial component that plays a vital role in our development and functioning. It is composed of three main layers - the ectoderm, endoderm, and mesoderm - which give rise to various tissues and organs throughout our lifetime. The germ layer is responsible for maintaining our immune system, reproductive system, and nervous system, among other essential functions. Disorders of the germ layer can lead to various health problems, such as developmental delays, immune system disorders, and reproductive issues. Germ cell transplantation, a type of stem cell therapy, has been used to treat some types of infertility and has great promise for future treatment options. Understanding the role of the germ layer is essential for developing new treatments for diseases and maintaining overall health and well-being.
