The formation of mesodermal clusters that are arranged segmentally along the anterior posterior axis of an embryo.

The formation of mesodermal clusters that are arranged segmentally along the anterior posterior axis of an embryo.

The process whose specific outcome is the progression of the neural plate over time, from its formation to the mature structure. The neural plate is a flat, thickened layer of ectodermal cells. The underlying dorsal mesoderm signals the ectodermal cells above it to elongate into columnar neural plate cells. The neural plate subsequently develops into the neural tube, which gives rise to the central nervous system.

The process in which precursor cell type acquires the specialized features of a hematopoietic progenitor cell, a class of cell types including myeloid progenitor cells and lymphoid progenitor cells.

Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

A series of molecular signals initiated by the binding of an extracellular ligand to the receptor Notch on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The establishment of an organism's body plan or part of an organism with respect to the left and right halves. The pattern can either be symmetric, such that the halves are mirror images, or asymmetric where the pattern deviates from this symmetry.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The regionalization process in which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism.

The process in which neuroepithelial cells in the neural tube acquire specialized structural and/or functional features of ventral spinal cord interneurons. Ventral spinal cord interneurons are cells located in the ventral portion of the spinal cord that transmit signals between sensory and motor neurons and are required for reflexive responses. Differentiation includes the processes involved in commitment of a cell to a specific fate.

Ventral spinal cord interneurons are cells located in the ventral portion of the spinal cord that transmit signals between sensory and motor neurons and are required for reflexive responses. Differentiation includes the processes involved in commitment of a cell to a specific fate.

The process in which neuroepithelial cells in the neural tube acquire specialized structural and/or functional features of somatic motor neurons. Somatic motor neurons innervate skeletal muscle targets and are responsible for transmission of motor impulses from the brain to the periphery. Differentiation includes the processes involved in commitment of a cell to a specific fate.

The process in which neuroepithelial cells in the ventral neural tube acquire specialized structural and/or functional features of radial glial cells. Radial cell precursors differentiate into both neuronal cell types and mature radial glial cells. Mature radial glial cells regulate the axon growth and pathfinding processes that occur during white matter patterning of the developing spinal cord. Differentiation includes the processes involved in commitment of a cell to a specific fate.

The progression of the habenula over time from its initial formation until its mature state. The habenula is the group of nuclei that makes up the stalk of the pineal gland.

The process whose specific outcome is the progression of the pancreas over time, from its formation to the mature structure. The pancreas is an endoderm derived structure that produces precursors of digestive enzymes and blood glucose regulating enzymes.

The process whose specific outcome is the progression of the exocrine pancreas over time, from its formation to the mature structure. The exocrine pancreas produces and store zymogens of digestive enzymes, such as chymotrypsinogen and trypsinogen in the acinar cells.

The progression of the dorsal aorta over time, from its initial formation to the mature structure. The dorsal aorta is a blood vessel in a single-pass circulatory system that carries oxygenated blood from the gills to the rest of the body. In a single-pass circulatory system blood passes once through the heart to supply the body once.

The dorsal aorta is a blood vessel in a single-pass circulatory system that carries oxygenated blood from the gills to the rest of the body. In a single-pass circulatory system blood passes once through the heart to supply the body once.

Any process that mediates the specification of a cell into an endoderm cell.

Any process that modulates the frequency, rate or extent of receptor mediated endocytosis, the uptake of external materials by cells, utilizing receptors to ensure specificity of transport.

Any process that activates or increases the frequency, rate or extent of mesoderm cell fate specification.

The process in which nerve cells are generated. This includes the production of neuroblasts and their differentiation into neurons.

Generation of a long process from a neuron whose cell body resides in the peripheral nervous system. The axon carries action potential from the cell body towards target cells.

Any process that stops, prevents, or reduces the frequency, rate or extent of neurogenesis, the generation of cells within the nervous system.

The process whose specific outcome is the progression of the hypochord over time, from its formation to the mature structure. The hypochord is a transient rod-like structure in the embryos of fish, lampreys and amphibians that is located immediately ventral to the notochord. The hypochord may play a role in positioning the dorsal aorta.

The process in which a relatively unspecialized cell acquires specialized features of a hematopoietic stem cell. A stem cell is a cell that retains the ability to divide and proliferate throughout life to provide progenitor cells that can differentiate into specialized cells.

The assembly of a cilium, a specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.

The series of molecular signals initiated by binding of an extracellular ligand to a Notch receptor on the surface of the target cell and contributing to the progression of the heart over time.

The orderly movement of a neuroblast from one site to another, often during the development of a multicellular organism or multicellular structure. A neuroblast is any cell that will divide and give rise to a neuron.
