There are a number of techniques that are commonly used in cell biology. Immunohistochemisty/ immunostaining is a useful histological technique that locates (tags) proteins in tissues and cells through fluorescence microscopy (towards various desired goals). Another common technique, cell culture, is used to grow cells under special conditions in the lab, outside a living organism while gene knock down is a method used to elicit mutation in a selected gene. Computational genomics identifies certain patterns in genomic data as DNA microarrays are essential in noting variations in transcript levels of various experimental circumstances. The method of PCR indicates the number of gene copies found in the cell and the process of transfection introduces into a cell an entirely new gene. To discover which cells are expressing a certain transcript of RNA, cell biologists use in situ hybridization. During cell biology, purification of cells can be accomplished using techniques such as flow cytometry, cell fractionation, immunoprecipitation, and so on (Pollard and William, 418).
Some of the processes of the cell commonly studied by cell biologists include active and passive transport, adhesion, cell movement, DNA repair (cell death and senescence), gene expression, metabolism, cell signaling, division and autophagy. Knowledge of cell biology is useful in fields such as cancer research and other disciplines like genetics, microbiology, immunology, molecular biology, developmental biology, biochemistry, anatomy, biostatistics, ecology, epidemiology, histology, mycology, reproductive biology, toxicology, virology, bacteriology, and so on (Pollard and William, ...Download file to see next pagesRead More

These stem cells, categorized sometimes according to their potency all play different roles in the human body, but they possess the three major unique characteristics. They are unspecialized and undifferentiated, can be induced to become cells with different functions and they do not differentiate to reproduce themselves but daughter cells.
