embryoid的音標是[?embri???d]，基本翻譯是“胚芽體”。速記技巧：可以將這個單詞分解成幾個部分來記憶。

Embryoid這個詞的詞源可以追溯到拉丁語“embryus”（胚胎）和“eoid”（形成）。它指的是一種由干細胞形成的、尚未發育完全的胚胎樣細胞團。

變化形式：在英語中，embryoid的形式沒有變化，始終寫作embryoid。

相關單詞：

1. embryologist：胚胎學家 - 這個詞由“胚胎”和“學家”組成，指研究胚胎發育的科學家。

2. embryogenesis：胚胎發生 - 這個詞由“胚胎”和“發生”組成，指胚胎發育的過程。

3. embryonate：胚胎化的 - 這個詞由“胚胎”和“化”組成，指某種東西或過程被胚胎化或變得像胚胎。

4. germplasm：種質 - 這個詞由“germ”（種子）和“plasm”（物質）組成，指包含遺傳信息的種子物質，也常用于描述植物和動物的種質資源。

5. germ：胚芽 - 這個詞來自拉丁語“germen”（生長），與embryoid有相似的含義，指的是尚未發育完全的胚胎或種子。

6. ovum：卵子 - 這個詞來自拉丁語“ovo”（卵），與embryoid有密切關系，因為卵子是胚胎發育的起點。

7. blastula：囊胚 - 這個詞由“blast”（膨脹）和“ula”（球）組成，指的是胚胎發育中的一個階段，此時胚胎被一個透明的囊狀結構包裹。

8. gastrula：囊胚 - 這個詞由“gastr”（胃）和“ula”（球）組成，指的是另一個胚胎發育階段，此時胚胎的內部組織開始分化為各種器官。

9. embryonics：胚胎學 - 這個詞由“embryo”（胚胎）和“ics”（學科）組成，指的是研究胚胎發育的學科。

10. embryotaxonomy：胚胎分類學 - 這個詞結合了“embryo”（胚胎）和“taxonomy”（分類學），指的是研究胚胎發育過程中生物分類的方法。

以上這些單詞都與embryoid有著密切的聯系，并且涵蓋了從胚胎學的理論到實際應用的各種方面。

常用短語：

1. embryoid body (Embryo body)

2. in vitro embryoid body (IV EB)

4. embryoid body formation (EBF)

5. embryoid body differentiation (EBD)

6. embryoid body culture (EBC)

7. embryoid body formation assay (EBFA)

雙語例句：

1. The cells were induced to form embryoid bodies in vitro. (細胞被誘導在體外形成胚胎球體。)

2. The embryoid bodies were then allowed to differentiate into different cell types. (然后胚胎球體被允許分化成不同的細胞類型。)

3. The embryoid bodies formed during the experiment were studied for their ability to differentiate into cells of the three germ layers. (實驗過程中形成的胚胎球體被研究其分化為三個胚層細胞的能力。)

4. Embryoid bodies are a useful tool for studying early stages of human development. (胚胎球體是研究人類早期發育階段的有用工具。)

5. The embryoid bodies showed a high degree of differentiation into cells of the three germ layers. (胚胎球體顯示出高度分化為三個胚層的細胞。)

6. Embryoid bodies can be used to study the effects of drugs on early human development. (胚胎球體可用于研究藥物對早期人類發育的影響。)

7. Embryoid bodies are a model system for studying the interactions between cells and their environment during early development. (胚胎球體是研究早期發育過程中細胞與其環境之間的相互作用的一種模型系統。)

英文小作文：

When we think about early human development, we often focus on the stages of pregnancy and birth, but one of the most exciting areas of research is studying the formation of embryoid bodies in the laboratory. These miniature organs, which are made up of cells that have been induced to behave like stem cells, can be used to study the earliest stages of human development and how cells differentiate into different types of tissue.

For example, by studying the embryoid bodies, scientists can gain a deeper understanding of diseases such as diabetes and Parkinson"s disease, which are often caused by abnormalities in early development. In addition, studying embryoid bodies can also help us to understand how to improve the efficiency of stem cell therapy, which is a promising field of research in regenerative medicine.

In conclusion, embryoid bodies are an incredibly powerful tool for studying early human development and have the potential to revolutionize our understanding of diseases and treatments for them.
