cell differentiation |
The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. |
cell maturation |
A developmental process, independent of morphogenetic (shape) change, that is required for a cell to attain its fully functional state. |
cellular response to progesterone stimulus |
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a progesterone stimulus. |
cellular response to xenobiotic stimulus |
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a xenobiotic, a compound foreign to the organism exposed to it. It may be synthesized by another organism (like ampicilin) or it can be a synthetic chemical. |
central nervous system myelination |
The process in which neuronal axons and dendrites become coated with a segmented lipid-rich sheath (myelin) to enable faster and more energetically efficient conduction of electrical impulses. The sheath is formed by the cell membranes of oligodendrocytes in the central nervous system. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier. |
developmental growth |
The increase in size or mass of an entire organism, a part of an organism or a cell, where the increase in size or mass has the specific outcome of the progression of the organism over time from one condition to another. |
digestive tract morphogenesis |
The process in which the anatomical structures of the digestive tract are generated and organized. The digestive tract is the anatomical structure through which food passes and is processed. |
enteric nervous system development |
The process whose specific outcome is the progression of the enteric nervous system over time, from its formation to the mature structure. The enteric nervous system is composed of two ganglionated neural plexuses in the gut wall which form one of the three major divisions of the autonomic nervous system. The enteric nervous system innervates the gastrointestinal tract, the pancreas, and the gall bladder. It contains sensory neurons, interneurons, and motor neurons. Thus the circuitry can autonomously sense the tension and the chemical environment in the gut and regulate blood vessel tone, motility, secretions, and fluid transport. The system is itself governed by the central nervous system and receives both parasympathetic and sympathetic innervation. |
in utero embryonic development |
The process whose specific outcome is the progression of the embryo in the uterus over time, from formation of the zygote in the oviduct, to birth. An example of this process is found in Mus musculus. |
lacrimal gland development |
The process whose specific outcome is the progression of the lacrimal gland over time, from its formation to the mature structure. The lacrimal gland produces secretions that lubricate and protect the cornea of the eye. |
melanocyte differentiation |
The process in which a relatively unspecialized cell acquires specialized features of a melanocyte. |
morphogenesis of a branching epithelium |
The process in which the anatomical structures of a branched epithelium are generated and organized. |
morphogenesis of an epithelium |
The process in which the anatomical structures of epithelia are generated and organized. An epithelium consists of closely packed cells arranged in one or more layers, that covers the outer surfaces of the body or lines any internal cavity or tube. |
negative regulation of apoptotic process |
Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process. |
negative regulation of canonical Wnt signaling pathway |
Any process that decreases the rate, frequency, or extent of the Wnt signaling pathway through beta-catenin, the series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes. |
negative regulation of DNA-templated transcription |
Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. |
negative regulation of Schwann cell proliferation |
Any process that decreases the frequency or extent of the multiplication or reproduction of Schwann cells, resulting in the expansion of their population. Schwann cells are a type of glial cell in the peripheral nervous system. |
negative regulation of transcription by RNA polymerase II |
Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II. |
neural crest cell migration |
The characteristic movement of cells from the dorsal ridge of the neural tube to a variety of locations in a vertebrate embryo. |
neuroblast proliferation |
The expansion of a neuroblast population by cell division. A neuroblast is any cell that will divide and give rise to a neuron. |
oligodendrocyte development |
The process aimed at the progression of an oligodendrocyte over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. An oligodendrocyte is a type of glial cell involved in myelinating the axons in the central nervous system. |
oligodendrocyte differentiation |
The process in which a relatively unspecialized cell acquires the specialized features of an oligodendrocyte. An oligodendrocyte is a type of glial cell involved in myelinating the axons of neurons in the central nervous system. |
peripheral nervous system development |
The process whose specific outcome is the progression of the peripheral nervous system over time, from its formation to the mature structure. The peripheral nervous system is one of the two major divisions of the nervous system. Nerves in the PNS connect the central nervous system (CNS) with sensory organs, other organs, muscles, blood vessels and glands. |
positive regulation of DNA-templated transcription |
Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription. |
positive regulation of gene expression |
Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA). |
positive regulation of gliogenesis |
Any process that activates or increases the frequency, rate or extent of gliogenesis, the formation of mature glia. |
positive regulation of myelination |
Any process that activates or increases the frequency, rate or extent of the formation of a myelin sheath around nerve axons. |
positive regulation of neuroblast proliferation |
Any process that activates or increases the rate of neuroblast proliferation. |
positive regulation of transcription by RNA polymerase II |
Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
regulation of DNA-templated transcription |
Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. |
regulation of transcription by RNA polymerase II |
Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II. |
transcription by RNA polymerase II |
The synthesis of RNA from a DNA template by RNA polymerase II (RNAP II), originating at an RNA polymerase II promoter. Includes transcription of messenger RNA (mRNA) and certain small nuclear RNAs (snRNAs). |
transcription elongation by RNA polymerase II promoter |
The extension of an RNA molecule after transcription initiation and promoter clearance at an RNA polymerase II promoter by the addition of ribonucleotides catalyzed by RNA polymerase II. |
