Meaning and Definition
A precursor cell that will develop into a melanin-producing cell (melanocyte).
In embryology and cell biology, an immature cell derived from the neural crest that migrates to various locations in the body (e.g., skin, hair follicles, eyes) and differentiates to synthesize melanin pigments.

- Using it to refer to a mature pigment cell.
- Confusing it with 'melanophage' (a cell that consumes melanin).
FAQ
Frequently Asked Questions
No. A melanoblast is an immature, developing precursor cell. A melanocyte is the mature, differentiated cell that actively produces and stores melanin.
They originate in the neural crest of an embryo and then migrate to various locations including the skin, eyes, inner ear, and hair follicles.
Understanding their development helps research into conditions like albinism (lack of pigment), vitiligo (loss of pigment), and melanoma (cancer arising from this cell lineage).
They can be identified using specialised staining techniques in histological samples, often distinguished by their location, shape, and expression of specific molecular markers.

Learning
Memory Aids
Mnemonic
Think: MELANO (black/dark pigment) + BLAST (germ/bud cell). A 'blast' cell is often an early, developing cell.
Conceptual Metaphor
CELL AS TRAVELLER: Melanoblasts migrate from their origin to their final destination.
