In cell biology, precursor cells —also called blast cells —are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells.
precursor. a form that precedes another. For example: (a) a substance that precedes and is involved in the synthesis of a compound, such as any of the intermediates in the synthesis of an AMINO ACID. (b) a cell from which other cells develop.
Nov 30, 2023 · A precursor in biology refers to a substance, cell, or cellular component that serves as a predecessor or antecedent for another substance, cell, or cellular component. This process typically occurs via natural biological mechanisms and often results in a formation of a molecule that is more active or mature than its original form.
A biosynthetic pathway actually describes a process of converting a precursor substrate into a product. In addition to the precursor substrate and product, it includes the enzymes, the chemical reactions catalyzed by the enzymes and all the intermediate compounds.
Precursor. In subject area: Immunology and Microbiology. Chemical vapor deposition (CVD) is an approach that entails the passing of precursor materials or gases toward heated substrates, encouraging chemical reaction to take place toward the surface of the substrate resulting in the formation of a solid deposit.
Precursor cells are stem cells that have developed to the stage where they are committed to forming a particular type of new blood cell. By dividing and differentiating, precursor cells give rise to the four major blood cell lineages: red cells, phagocytic cells, megakaryocytes, and…
A protein precursor, also called a pro-protein or pro-peptide, is an inactive protein (or peptide) that can be turned into an active form by post-translational modification, such as breaking off a piece of the molecule or adding on another molecule.
