Any process involved in the controlled self-propelled movement of a cell that contributes to somitogenic axis elongation.

The developmental growth that results in the elongation of the rostral-caudal axis that contributes to somitogenesis.

The series of molecular signals initiated by binding of Wnt protein to a frizzled family receptor on the surface of the target cell and ending with a change in cell state that contributes to somitogenesis.

The morphogenetic process in which a presomitic mesoderm narrows along the left-right axis and lengthens in the rostral-caudal axis contributing to somitogenesis.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands that contributes to somitogenesis.

The series of molecular signals generated as a consequence of a retinoic acid receptor binding to one of its physiological ligands that contributes to somitogenesis.

Any process that increases the rate, frequency, or extent of arachidonic acid secretion, the controlled release of arachidonic acid from a cell or a tissue.

Any process that modulates the rate, frequency, or extent of centromere complex assembly, the aggregation, arrangement and bonding together of proteins and centromeric DNA molecules to form a centromeric protein-DNA complex.

OBSOLETE. Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter that contributes to the formation of mesodermal clusters that are arranged segmentally along the anterior posterior axis of an embryo.

Any process that modulates the rate, frequency, or extent of metaphase plate congression, the alignment of chromosomes at the metaphase plate, a plane halfway between the poles of the spindle.

Any process that modulates the rate, frequency or extent of the red or far-red signaling pathway, the series of molecular signals initiated upon sensing by photoreceptor molecules of red light or far red light.

The series of molecular signals in which a Ran GTPase relays a signal resulting in the modulation of the rate, frequency or extent of microtubule nucleation.

Any process that decreases the rate, frequency or extent of the red or far-red signaling pathway, the series of molecular signals initiated upon sensing by photoreceptor molecules of red light or far red light.

Any process that increases the rate, frequency or extent of the red or far-red signaling pathway, the series of molecular signals initiated upon sensing by photoreceptor molecules of red light or far red light.

The 'de novo' formation of a microtubule, in which tubulin heterodimers form metastable oligomeric aggregates from chromatin.

The 'de novo' formation of a microtubule, in which tubulin heterodimers form metastable oligomeric aggregates from the centrosome.

Any process that modulates the number of microtubules in a given region of the spindle.

The 'de novo' formation of a microtubule, in which tubulin heterodimers form metastable oligomeric aggregates from within the mitotic spindle.

The series of molecular signals initiated by binding of a Wnt protein to a receptor on the surface of the target cell where activated receptors signal via downstream effectors that modulates the establishment of planar polarity contributing to neural tube closure.
