Blastema

Blastema (pronounced: /blæˈstiːmə/) is a mass of cells capable of growth and regeneration into organs or body parts.

Etymology

The term "blastema" is derived from the Greek word "blastos" meaning "sprout" and "ema" meaning "condition". It was first used in the 19th century to describe the regenerative tissue in plants and animals.

Definition

In Biology, a blastema is a group of cells that have the ability to develop into a type of organ or tissue. It is often seen in organisms that have the capability for regeneration, such as salamanders and starfish. The cells in a blastema are undifferentiated, meaning they can develop into various types of cells.
