The initial step in phagocytosis involving adhesion to bacteria, immune complexes and other particulate matter, or an apoptotic cell and based on recognition of factors such as bacterial cell wall components, opsonins like complement and antibody or protein receptors and lipids like phosphatidyl serine, and leading to intracellular signaling in the phagocytosing cell.

The internalization of bacteria, immune complexes and other particulate matter or of an apoptotic cell by phagocytosis, including the membrane and cytoskeletal processes required, which involves one of three mechanisms: zippering of pseudopods around a target via repeated receptor-ligand interactions, sinking of the target directly into plasma membrane of the phagocytosing cell, or induced uptake via an enhanced membrane ruffling of the phagocytosing cell similar to macropinocytosis.

Specification of the anterior (head and thoracic segments) of the embryo by the gap genes; exemplified in insects by the actions of hunchback gene product.

Any process that activates or increases the rate or extent of cell proliferation.

Any process that increases the frequency, rate or extent of cell-substrate adhesion. Cell-substrate adhesion is the attachment of a cell to the underlying substrate via adhesion molecules.

The creation of specific areas of progenitor domains along the anterior-posterior axis of the developing forebrain.

The process occurring during the embryonic phase whose specific outcome is the progression of the eye over time, from its formation to the mature structure.

Any process that increases the rate of growth of all or part of an organism.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of stimulus by an estrogen, C18 steroid hormones that can stimulate the development of female sexual characteristics.

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

Any process that activates or increases the frequency, rate or extent of phagocytosis.

The process in which the anatomical structures of the head are generated and organized. The head is the anterior-most division of the body.

The commitment of neurectodermal cells to cells of the eye field and their capacity to differentiate into eye field cells. Eye field cells are neurectodermal cells that will form the optic placode.

The developmental process pertaining to the initial formation of a camera-type eye from unspecified neurectoderm. This process begins with the differentiation of cells that form the optic field and ends when the optic cup has attained its shape.

The process whose specific outcome is the progression of the cement gland over time, from its formation to the mature structure. The cement gland is a simple mucus-secreting organ positioned at the anterior of amphibious embryos. The cement gland attaches the newly hatched embryo to a support before the hatchling can swim well or feed.

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.

Any process that activates or increases the frequency, rate or extent of apoptotic cell clearance.

A structure lying external to one or more cells, which provides structural support for cells or tissues.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

Any vesicle that is part of the extracellular region.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region.

A structure lying external to one or more cells, which provides structural support for cells or tissues.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

Any vesicle that is part of the extracellular region.
