Cell Adhesion Molecules, Neuron-Glia
|
D019062 |
[Cell adhesion molecules that mediate neuron-neuron adhesion and neuron-astrocyte adhesion. They are expressed on neurons and Schwann cells, but not astrocytes and are involved in neuronal migration, neurite fasciculation, and outgrowth. Ng-CAM is immunologically and structurally distinct from NCAM.

Cell Adhesion Molecules, Neuronal
|
D015816 |
[Surface ligands that mediate cell-to-cell adhesion and function in the assembly and interconnection of the vertebrate nervous system. These molecules promote cell adhesion via a homophilic mechanism. These are not to be confused with NEURAL CELL ADHESION MOLECULES, now known to be expressed in a variety of tissues and cell types in addition to nervous tissue.

Cell Aggregation
|
D002449 |
[The phenomenon by which dissociated cells intermixed in vitro tend to group themselves with cells of their own type.

|
Cell Biology
|
D003585 |
[The study of the structure, behavior, growth, reproduction, and pathology of cells; and the function and chemistry of cellular components.
] |
|
Cell Body
|
D066146 |
[The portion of a cell that contains the NUCLEUS and CYTOPLASM but not CELL SURFACE EXTENSIONS such as FLAGELLA and NEURITES.
] |
|
Cell Communication
|
D002450 |
[Any of several ways in which living cells of an organism communicate with one another, whether by direct contact between cells or by means of chemical signals carried by neurotransmitter substances, hormones, and cyclic AMP.

|
Cell Compartmentation
|
D002451 |
[A partitioning within cells due to the selectively permeable membranes which enclose each of the separate parts, e.g., mitochondria, lysosomes, etc.
] |
|
Cell Competition
|
D000084502 |
[A cellular process that selectively eliminates cells with mutations from further development through short-range cell-cell interaction.
] |
|
Cell Count
|
D002452 |
[The number of CELLS of a specific kind, usually measured per unit volume or area of sample.
] |
|
Cell Culture Techniques
|
D018929 |
[Methods for maintaining or growing CELLS in vitro.

|
Cell Cycle
|
D002453 |
[The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.

|
Cell Cycle Checkpoints
|
D059447 |
[Cellular mechanisms that ensure that all events occuring during specific times in the CELL CYCLE are completed and without mistakes prior to progression to the next phase of the cell cycle.
, Regulatory signaling systems that control the progression through the CELL CYCLE. They ensure that the cell has completed, in the correct order and without mistakes, all the processes required to replicate the GENOME and CYTOPLASM, and divide them equally between two daughter cells. If cells sense they have not completed these processes or that the environment does not have the nutrients and growth hormones in place to proceed, then the cells are restrained (or "arrested") until the processes are completed and growth conditions are suitable.
, The halting of progression of a cell through the CELL CYCLE when events in the CELL DIVISION process are not completed accurately or damage to cell components in the process are detected.

|
Cell Cycle Proteins
|
D018797 |
[Proteins that control the CELL DIVISION CYCLE. This family of proteins includes a wide variety of classes, including CYCLIN-DEPENDENT KINASES, mitogen-activated kinases, CYCLINS, and PHOSPHOPROTEIN PHOSPHATASES as well as their putative substrates such as chromatin-associated proteins, CYTOSKELETAL PROTEINS, and TRANSCRIPTION FACTORS.
] |
|
Cell Death
|
D016923 |
[The termination of the cell's ability to carry out vital functions such as metabolism, growth, reproduction, responsiveness, and adaptability.
] |
|
Cell Dedifferentiation
|
D054337 |
[A reverse developmental process in which terminally differentiated cells with specialized functions revert back to a less differentiated stage within their own CELL LINEAGE.
] |
|
Cell Degranulation
|
D015550 |
[The process of losing secretory granules (SECRETORY VESICLES). This occurs, for example, in mast cells, basophils, neutrophils, eosinophils, and platelets when secretory products are released from the granules by EXOCYTOSIS.
] |
|
Cell Differentiation
|
D002454 |
[Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs.
] |
|
Cell Division
|
D002455 |
[The period of the cell cycle when CELLS divide their nucleus and cytoplasm.
, The fission of a CELL. It includes CYTOKINESIS, when the CYTOPLASM of a cell is divided, and CELL NUCLEUS DIVISION.
] |
|
Cell Encapsulation
|
D000079585 |
[The encapsulation of cells into semi-permeable microcapsules or MICROSPHERES that permits protection of encapsulated cells and allows passage of essential nutrients and release of a therapeutic product (e.g. INSULIN).
] |
|
Cell Engineering
|
D060846 |
[Methods and techniques used to modify or select cells and develop conditions for growing cells for biosynthetic production of molecules (METABOLIC ENGINEERING), for generation of tissue structures and organs in vitro (TISSUE ENGINEERING), or for other BIOENGINEERING research objectives.
