The process, occurring in the embryo, by which the anatomical structures of the limb are generated and organized. A limb is an appendage of an animal used for locomotion or grasping.

The process in which the anatomical structures of a leg derived from an imaginal disc are generated and organized. A leg is a limb on which an animal walks and stands. An example of this is found in Drosophila melanogaster.

Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

The process whereby a relatively unspecialized cell acquires the specialized features of an osteoblast, a mesodermal or neural crest cell that gives rise to bone.

Any process that modulates the rate, frequency, or extent of gene silencing, the transcriptional or post-transcriptional process carried out at the cellular level that results in long-term gene inactivation.

The process whereby a relatively unspecialized cell acquires the specialized features of an osteoblast, a mesodermal or neural crest cell that gives rise to bone.

Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II.

Any process that modulates the frequency, rate or extent of transcription mediated 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).

The regionalization process in which the areas along the dorsal/ventral axis are established that will lead to differences in cell differentiation. The dorsal/ventral axis is defined by a line that runs orthogonal to both the anterior/posterior and left/right axes. The dorsal end is defined by the upper or back side of an organism. The ventral end is defined by the lower or front side of an organism.

The regionalization process in which specific areas of cell differentiation are determined along a proximal/distal axis. The proximal/distal axis is defined by a line that runs from main body (proximal end) of an organism outward (distal end).

Any process that modulates the frequency, rate or extent of osteoblast proliferation.

The process, occurring in the embryo, by which the anatomical structures of the pectoral fin are generated and organized. Pectoral fins are bilaterally paired fins mounted laterally and located behind the gill covers of fish. These fins are used for lateral mobility and propulsion.

Any process that modulates the frequency, rate or extent of the formation and development of a tooth or teeth.

Any process that activates or increases the frequency, rate or extent of fibroblast growth factor receptor signaling pathway activity.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

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 process in which any suture between cranial bones is generated and organized.

The process whose specific outcome is the formation of dentin, the mineralized tissue that constitutes the major bulk of teeth. Dentin may be one of three types: primary dentin, secondary dentin, and tertiary dentin.

Any process that activates or increases the frequency, rate or extent of stem cell differentiation.

Any process that activates or increases the frequency, rate or extent of stem cell differentiation.

Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.

Formation of a partial necklace of inturning tissue on the lateral sides of the embryo, along the dorsal-ventral axis. This furrow demarcates head from thorax in the developing protostome.

Partitioning the insect head anlage into procephalic (labral, (ocular), antennal and intercalary) segments. The procephalic segments lie anterior to the gnathal (posterior head) segments, and are pattered by different segmentation gene cascades to the abdominal, thoracic and posterior head (gnathal) segments.

Partitioning the posterior region of the insect head anlage into gnathal (mandibular, maxillary and labial) segments. Unlike the anterior head (procephalic) segments, formation of the posterior head (gnathal) segments occurs by a similar mechanism to trunk segmentation, where a cascade of gap genes, pair-rule genes and segment-polarity genes subdivide the embryo into progressively smaller domains.

Any process that modulates the frequency, rate or extent of neuron differentiation.

Any process that modulates the frequency, rate or extent of neuroblast proliferation.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A stretch of densely packed chromatin along the polytene chromosome, visible as a morphologically distinct band.

That part of the nuclear content other than the chromosomes or the nucleolus.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
