Amelogenesis 1 Flashcards
(10 cards)
Induction
The process by which one group of cells or tissues influences the development or differentiation of
adjacent cells or tissues. It involves the signalling and interaction between cells to initiate specific
developmental pathways.
Morphogenesis
The biological process that causes an organism to develop its shape. It encompasses the cellular
and tissue-level changes that lead to complex structures and organs forming during development.
Amelogenesis
The process of enamel formation, where enamel-forming cells called ameloblasts produce and
mineralize enamel, the hard outer layer of the tooth.
Cell-fate determination
The process by which a cell becomes committed to a specific developmental pathway or lineage,
leading to the differentiation into a particular cell type with specialized functions.
Apoptosis:
Also known as programmed cell death, is a regulated and controlled process of cell suicide
that occurs in multicellular organisms.
Proliferation
The increase in the number of cells through cell division.
Differentiation
The process by which cells become specialized and acquire distinct morphological and
functional characteristics. It involves gene expression and cellular function changes to give
rise to specific cell types with specialized roles.
Stem cells
Undifferentiated cells that have the potential to differentiate into various cell types and
contribute to the renewal and repair of tissues.
enamel knot
is a reservoir of signaling pathway-related genes and signaling molecules that allow tooth morphogenesis to progress toward the bell stage and regulate the tooth’s shape. How many cusps dependent on this
Tomes Process
a finger-like projection of the ameloblast, occurring during the secretory phase of the cell during amelogenesis, which extends from the point of separation. They have the appearance of a picket fence microscopically.
