dedifferentiation

Thân thiện

A cell undergoes dedifferentiation in a laboratory culture.

Definition

1. Noun:
   • The loss of specialization in form or function: In biology, "dedifferentiation" refers to the process by which specialized or differentiated cells revert to a less specialized, more primitive state. This often involves the loss of specific structures and functions that characterize the mature cell type.

Usage

• "Dedifferentiation" is a technical term used primarily in cell biology, developmental biology, and medicine.
• It describes a cellular process that is the reverse of normal cell maturation (differentiation).
• It is often discussed in contexts such as regeneration, wound healing, and the formation of certain tumors.

Examples

• Noun:
  • The dedifferentiation of muscle cells is a key step in the regeneration of a salamander's limb.
  • Scientists are studying the mechanisms that control cellular dedifferentiation.
  • In some cancers, dedifferentiation of cells leads to more aggressive tumor growth.

Advanced Usage

• "to undergo dedifferentiation": to experience the process of losing specialization.
  • When injured, the mature cells at the site must undergo dedifferentiation before they can proliferate and repair the tissue.

Variants and Related Words

• Dedifferentiate (verb): to lose specialization and revert to a more primitive form.
  • Under specific conditions, these specialized cells can dedifferentiate.
• Dedifferentiated (adjective): having undergone dedifferentiation.
  • The biopsy showed dedifferentiated tumor cells.

Synonyms

• Regression (in a biological, cellular context).
• Reversion (to a less specialized state).

Antonyms

• Differentiation: the process by which cells become specialized in structure and function.
• Specialization: the adaptation of a cell for a particular function.
