Definitions

1. A type of tissue that has the potential to develop into various differentiated cells, often involved in regeneration or growth processes
2. Cells or tissues characterized by their capability to form new structures or regenerate, playing a key role in developmental biology

Etymology: "Blastemata" is the plural of "blastema," a word for the mass of cells that forms at the site of an injury or in a growing limb and can develop into several different kinds of tissue. The plural follows the Greek pattern, since the singular ends in the neuter "-ma" ending that Greek nouns often take. The word comes from Ancient Greek "blástēma," meaning "sprout" or "shoot," which is related to the verb "blastanein," meaning "to bud" or "to sprout." That image of new growth from a living organism is what the modern term keeps. Biologists borrowed the Greek word as a technical label, so the notion of a sprouting bud, a point where new structure begins, stayed attached to it.

Synonyms: blastemas, embryonic tissue, regenerative tissue
