  2. Cytokinesis - Wikipedia

    en.wikipedia.org/wiki/Cytokinesis

    Cytokinesis illustration Ciliate undergoing cytokinesis, with the cleavage furrow being clearly visible. Cytokinesis (/ ˌ s aɪ t oʊ k ɪ ˈ n iː s ɪ s /) is the part of the cell division process and part of mitosis during which the cytoplasm of a single eukaryotic cell divides into two daughter cells.

  3. Cytokine - Wikipedia

    en.wikipedia.org/wiki/Cytokine

    Cytokines (/'saɪ.tə.kaɪn/) [1] are a broad and loose category of small proteins (~5–25 kDa [2]) important in cell signaling. Due to their size, cytokines cannot cross the lipid bilayer of cells to enter the cytoplasm and therefore typically exert their functions by interacting with specific cytokine receptors on the target cell surface.

  4. Inflammatory cytokine - Wikipedia

    en.wikipedia.org/wiki/Inflammatory_cytokine

    An inflammatory cytokine or proinflammatory cytokine is a type of signaling molecule (a cytokine) that is secreted from immune cells like helper T cells (T h) and macrophages, and certain other cell types that promote inflammation.

  5. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.

  6. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    At the peak of the cyclin, attached to the cyclin dependent kinases this system pushes the cell out of interphase and into the M phase, where mitosis, meiosis, and cytokinesis occur. [19] There are three transition checkpoints the cell has to go through before entering the M phase. The most important being the G 1-S transition checkpoint. If ...

    Though one's body produces peptides naturally, peptides are also found in many food and supplement sources. "All the food we eat is broken down by the body into amino acids," explains Stevenson.

  8. Polar body - Wikipedia

    en.wikipedia.org/wiki/Polar_body

    A polar body is a small haploid cell that is formed at the same time as an egg cell during oogenesis, but generally does not have the ability to be fertilized. It is named from its polar position in the egg. When certain diploid cells in animals undergo cytokinesis after meiosis to produce egg cells
