The process whose specific outcome is the progression of any organ involved in hematopoiesis (also known as hemopoiesis) or lymphoid cell activation over time, from its formation to the mature structure. Such development includes differentiation of resident cell types (stromal cells) and of migratory cell types dependent on the unique microenvironment afforded by the organ for their proper differentiation.

A process in which non-proliferating myoblasts fuse to existing fibers or to myotubes to form new fibers. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers.

The process whose specific outcome is the progression of the posterior lateral line over time, from its formation to the mature structure. The posterior lateral line consists of small sensory patches (neuromasts) located superficially on the skin or just under the skin in fluid-filled canals on the body and trunk of all fishes and most amphibians. The posterior lateral line develops from cranial ectodermal placodes situated behind the ear.

Any process that modulates the frequency, rate or extent of hematopoietic stem cell differentiation.

Any process that modulates the frequency, rate, or extent of production of a cytokine.

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell adhesion.

The attachment of one cell to another cell via adhesion molecules, where both cells are part of the same organism.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.

The process in which a relatively unspecialized cell acquires specialized features of an epithelial cell, any of the cells making up an epithelium.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures containing both actin and myosin or paramyosin. The myosin may be organized into filaments.

Any process that stops or reduces the rate of GTP hydrolysis by a GTPase.

Any process that activates or increases the activity of a GTPase.

Any process in which nutrients are taken up from the contents of the intestine.

Any process in which nutrients are taken up from the contents of the intestine.

The movement of a leukocyte within or between different tissues and organs of the body.

The directed movement of a protein to a specific location in the plasma membrane.

The establishment of a barrier between endothelial cell layers of the intestine to exert specific and selective control over the passage of water and solutes, thus allowing formation and maintenance of compartments that differ in fluid and solute composition.

Any process that modulates the frequency, rate or extent of the passage or uptake of molecules by a membrane.

Any process that modulates the frequency, rate or extent of the passage or uptake of molecules by a membrane.

Any process that modulates the frequency, rate or extent of actin cytoskeleton reorganization.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

An occluding cell-cell junction that is composed of a branching network of sealing strands that completely encircles the apical end of each cell in an epithelial sheet; the outer leaflets of the two interacting plasma membranes are seen to be tightly apposed where sealing strands are present. Each sealing strand is composed of a long row of transmembrane adhesion proteins embedded in each of the two interacting plasma membranes.

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.
