Stem cells, which are extracted from embryos when the embryos are still microscopic clusters of cells, have the potential to grow into any of the body's more than 200 cell types.
Virtually all cells have microscopic "power plants" called mitochondria, where energy sources such as sugars and fats are burned to produce a compound called ATP, the universal "coin" of the body's economy.
Various cell types can be observed in the hymenium, and the cells have microscopic characteristics that may be used to help identify or distinguish species in cases where the macroscopic characters may be ambiguous.
PA 16/23 cells have light microscopic, immunophenotypical and ultrastructural features of immature myoepithelial cells, i.e. they are of fusiform or stellate shape and show keratin and actin cytofilaments located mainly in the perinuclear cytoplasm, desmosomes and tracts of basal lamina.
It appears that these large cells have the light microscopic and histochemical characteristics of true Gaucher cells but, when studied with immunofluorescence and electron microscopy, it appears that the pseudo-Gaucher cells of multiple myeloma are bone marrow macrophages engorged with immunoglobulin.
The cells at mid-log phase were used for microscopic observation because at this phase yeast cells have adapted to new condition of medium.
Several methods for detecting pseudopods automatically or semi-automatically in microscopic cell movies have been proposed previously.
After a few days, your microscopic ball of cells has divided into a thin sheet of muscle tissue big enough to cover the bottom of a flask.
In addition to microscopic venous invasion, tumor cells had extensively invaded the portal vein, resulting in a tumor thrombus in the left portal vein.
Specifically, electron microscopic examination of these cells has evidenced desmosomes, intracytoplasmic filaments, filopodia, and microvilli [ 12, 13, 25, 26].
