germ layer：/d???rm/ layer/le?/

基本翻譯：胚層。

速記技巧：germ（細菌）＋layer（層）→胚層，可以諧音聯想為“蓋兒（germ）來（layer）胚層”。

Germline layer是細胞生物學中的術語，指的是一種細胞類型，通常存在于動物胚胎的原始組織中。它的英文詞源可以追溯到拉丁語“germen”和“linea”，意為“種子”和“線”，表示這種細胞類型是從受精卵發育而來的。

Germline layer的變化形式主要是復數形式“germline layers”或簡寫為“germ layers”。

相關單詞有：

1. “cell lineage”意為細胞譜系，指的是一個細胞或一群細胞的發育過程。

2. “embryonic development”意為胚胎發育，指的是從受精卵到出生前的生長過程。

3. “germ cell”意為生殖細胞，指的是能夠繁殖后代的細胞，如精子和卵子。

4. “germinal layer”意為原始層，指的是胚胎早期存在的一種細胞層，其中包含各種類型的細胞前體。

5. “neural crest”意為神經突起，是一種在胚胎發育過程中形成的細胞群，能夠分化為神經元和膠質細胞。

6. “mesoderm”意為中胚層，是動物胚胎的一種重要組織，包含許多不同類型的細胞，如肌肉、骨骼和內臟器官的原始細胞。

7. “epithelium”意為上皮層，指的是覆蓋在身體表面或封閉腔內的細胞層，如皮膚和腸粘膜。

8. “progenitor cell”意為祖細胞，指的是能夠分化為其他細胞的細胞，在胚胎發育和組織再生中扮演重要角色。

9. “stem cell”意為干細胞，指的是能夠自我更新并分化為多種類型細胞的細胞，在醫學上具有廣泛的應用前景。

10. “fate”意為命運，指的是一個細胞或一個生物體的未來發展路徑。與germline layer相關的命運包括分化為特定類型的細胞或最終成為生物體的某個部分。

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.
