A cell part consisting of multiple, closely packed actin-based cell projections.

Division of the central nervous system into a series of semi-repetitive parts or segments.

The directed movement of the nucleus by pushing forces exerted by polymerization of backward-extending microtubules.

Division of the brain into a series of semi-repetitive parts or segments.

The process in which a symbiont organism effects a change in the structure or function of its host tight junction, a cell-cell junction that seals cells together in an epithelium in a way that prevents even small molecules from leaking from one side of the sheet to the other.

The process whose specific outcome is the progression of the hair follicle over time, from its formation to the mature structure. A hair follicle is a tube-like opening in the epidermis where the hair shaft develops and into which the sebaceous glands open.

The process in which an organism effects a change in the structure or function of its host bicellular tight junctions, 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 fusion of the membrane of a multivesicular body with the apical plasma membrane, resulting in release of exosomes from the cell.

Fusion of the membrane of a vesicle with the plasma membrane, thereby releasing its contents into the extracellular space.

The pronucleus originating from the spermatozoa that was involved in fertilization.

The increase in size or mass of an intramembranous bone that contributes to the shaping of the bone.

The increase in size or mass of a bone that contributes to the shaping of that bone.

Binds to and stops, prevents or reduces the activity of lysozyme.

The series of events in which information about the density of cells in a population is received by direct cell-cell contact and is converted into a molecular signal, resulting in the cessation of cell growth or proliferation.

Any process that decreases the rate, frequency or extent of the series signal transduction involved in conjugation with cellular fusion.

Any process that modulates the rate, frequency or extent of the non-sexual aggregation of single-celled organisms.

An RNA interference pathway in which microRNAs (miRNAs) block the translation of target mRNAs into proteins. Once incorporated into a RNA-induced silencing complex (RISC), a miRNA will typically mediate repression of translation if the miRNA imperfectly base-pairs with the 3' untranslated regions of target mRNAs.

A post-transcriptional gene silencing pathway in which regulatory microRNAs (miRNAs) elicit silencing of specific target genes. miRNAs are endogenous 21-24 nucleotide small RNAs processed from stem-loop RNA precursors (pre-miRNAs). Once incorporated into a RNA-induced silencing complex (RISC), miRNAs can downregulate gene expression by either of two posttranscriptional mechanisms: endonucleolytic cleavage of the RNA (often mRNA) or mRNA translational repression, usually accompanied by poly-A tail shortening and subsequent degradation of the mRNA. miRNAs are present in all the animals and in plants, whereas siRNAs are present in lower animals and in plants.

Any process that decreases the rate, frequency or extent of the non-sexual aggregation of single-celled organisms.
