Definition
Meaning and Definition
A mass of undifferentiated cells from which an organ or body part develops.
In biology and medicine, a cluster of living, actively dividing cells capable of growth and regeneration into tissues or organs. In developmental biology, it refers to the precursor cells for limb or structure regeneration in certain animals.

Common Mistakes When Using “blastema”

FAQ
Frequently Asked Questions
Not exactly. A blastema is a mass or structure containing undifferentiated cells (which can include stem cells or dedifferentiated cells) that is specifically organised for regenerating a particular organ or appendage. 'Stem cells' is a broader category.
Humans have limited regenerative abilities and do not typically form complex blastemas like salamanders. However, some research suggests blastema-like processes may occur in very specific contexts, like fingertip regeneration in children.
A blastema is an organised, controlled growth for regeneration. A tumour (like a blastoma) is an uncontrolled, disorganised proliferation of cells. They are fundamentally different in purpose and regulation.
No. 'Blastema' is a highly specialised scientific term. You will only encounter it in specific academic or technical contexts related to biology and medicine.
A mass of undifferentiated cells from which an organ or body part develops.
Blastema is usually technical/scientific in register.
Blastema: in British English it is pronounced /blæˈstiːmə/, and in American English it is pronounced /blæˈstimə/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'BLAST-off for new tissue!' A BLASTema is the starting point (like a rocket launch pad) from which new body parts BLAST off and grow.
Conceptual Metaphor
A CONSTRUCTION SITE FOR THE BODY. The blastema is like the raw materials and blueprints gathered before building a new structure (organ/limb).
