For the first time, scientists have peered into living cells and created videos showing how they function with unprecedented 3D detail. Using a special microscope and new lighting techniques, a ...
To keep cells alive during observation, the microscopes are commonly enclosed in a micro cell incubator (the transparent box). Live-cell imaging is the study of living cells using time-lapse microscopy. It is used by scientists to obtain a better understanding of biological function through the study of cellular dynamics.

A reaction occurs between the antigen and antibody, causing this label to become visible under the microscope. Scanning electron microscopy is a viable option if the antigen is on the surface of the cell, but transmission electron microscopy may be needed to see the label if the antigen is within the cell.

Multiple FS cell lines have been developed to try to observe the location and function of these cells. mRNA levels of FS cells has been investigated via laser capture microdissection and RT-PCR, so progress is being made in terms of understanding the expression and function of these non-endocrine cells of the pituitary.

Electron microscopy is a common method that uses the immunolabeling technique to view tagged tissues or cells. The electron microscope method follows many of the same concepts as immunolabeling for light microscopy, where the particular antibody is able to recognize the location of the antigen of interest and then be viewed by the electron ...
Histologic specimen being placed on the stage of an optical microscope. Human lung tissue stained with hematoxylin and eosin as seen under a microscope.. Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues.
Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
The transmission electron microscope (TEM) is used as an important diagnostic tool to screen human tissues at high magnification and at high resolution (the ultrastructural level), often in conjunction with other methods, particularly light microscopy and immunofluorescence techniques.
