Definition

1. Noun (Biology, Anatomy):
   • Teloblast: A large, specialized cell found in the embryos of some invertebrates (e.g., annelids, arthropods). Teloblasts are stem cells that divide repeatedly to produce a linear series of smaller cells (blast cells), which then form specific segmented tissues, such as the body wall or nervous system, during embryonic development.

Usage Examples

• Noun:
  • Trong quá trình phát triển phôi của giun đốt, các đối bào đóng vai trò then chốt. (During annelid embryonic development, teloblasts play a key role.)
  • Mỗi đối bào sẽ tạo ra một dòng tế bào cho một đốt cơ thể. (Each teloblast will generate a cell lineage for one body segment.)

Advanced Usage

• This term is highly specialized and is used almost exclusively in academic contexts within embryology, developmental biology, and invertebrate zoology.

Variants and Related Words

• Sự phân chia đối bào: Teloblastic division.
  • Sự phân chia đối bào là cơ chế quan trọng để hình thành cơ thể phân đốt. (Teloblastic division is an important mechanism for forming a segmented body.)

Synonyms

• Teloblast: The direct and only accurate English equivalent.

Related Terms (Conceptual)

• Blast cell: A smaller cell derived from a teloblast.
• Teloblastic lineage: The series of cells descended from a single teloblast.
• Spiral cleavage: A type of embryonic cleavage in which teloblasts are often involved.
