    Cell biology (also called cellular biology or cytology, from the Greek languageGreek ''kytos'', "container") is an list of academic disciplinesacademic discipline which studies cell (biology)cells. This includes their physiologyphysiological properties such as their structure and the organelles they contain, their environment and interactions, their cell cyclelife cycle, cell divisiondivision and function (physiology) and eventual apoptosisdeath. This is done both on a microscopemicroscopic and moleculemolecular level, and cell biology researches both single-celled organisms like bacteriumbacteria and specialized cells in multicellular organisms like humans.Knowing the composition of cells and how cells work is fundamental to all of the biological sciences. Appreciating the similarities and differences between cell types is particularly important to the fields of cell and molecular biology. These fundamental similarities and differences provide a unifying theme, allowing the principles learned from studying one cell type to be extrapolated and generalized to other cell types.Research in cell biology is closely related to genetics, biochemistry, molecular biology and developmental biology.

    Processes in cell biology -

    Movement of proteins - Proteins are synthesized by ribosomes in the cytoplasm. This process is also known as protein biosynthesis or simply translation (genetics)protein translation. Some proteins, such as those to be incorporated in membranes (membrane proteins), are transported into the endoplasmic reticulumER during synthesis and further processed in the Golgi apparatus. From the Golgi, membrane proteins can move to the plasma membrane, to other subcellular comparments or they can be secreted from the cell. The ER and Golgi can be thought of as the "membrane protein synthesis compartment" and the "membrane protein processing compartment", respectively. There is a semi-constant flux of proteins through these compartments. ER and Golgi-resident proteins associate with other proteins but remain in their respective compartments. Other proteins "flow" through the ER and Golgi to the plasma membrane. From the plasma membrane, proteins destined to be degraded move back into intracellular compartments where they are broken down to their individual amino acids.

    Techniques -

    Purification of cells and their parts - Purification of cells and their parts is achieved in the following ways:
  • Cell fractionation
  • Flow cytometry
  • Release of cellular organelles by disruption of cells.
  • Separation of different organelles by centrifugation.
  • Proteins extracted from membranes by detergents and salts.

    The Society's objective is to provide for the exchange of scientific knowledge in the area of cell biology. It does so through the scholarly dissemination of research at its Annual Meeting and in its publications, and strives to ensure the future of basic scientific research by providing training and development opportunities for students and young investigators, and also by keeping Congress and the American public informed on the importance of biomedical research.
