Under a microscope's bright light, without stains the various cells and organelles within the cells are a washed-out pale mess. The stains give contrast and definition to the cell wall and some of the organelles within the cell so the pathologist can see what is going on.

Diff between progressive staining and regressive staining?
REGRESSIVE STAINING. In a regressive stain, the tissue is first over stained and then partially decolorized. Differentiation is usually controlled visually by examination with a microscope. When regressive staining is employed, a sharper degree of differentiation is obtained than with progressive staining .PROGRESSIVE STAINING. In progressive staining, once the dye is taken up by the tissue it is not removed. Differentiation in progressive staining relies solely on the selective affinity of dyes for different tissue elements. The tissue is left in the dye solution only until it retains the desired amount of coloration.
What are the most common staining methods in Tissue Engineering. I know HE staining but what else?
H & E staining is good as a primary staining method alone. The selection of a relevant staining method depends on the type of sample you are planning to visualize. Re post with said detail to help you pick the right stain.
What is an antonym for tissue?
Tissue refers to an object and does not have an antonym
Can cells be stained with dye?
Live staining is possible as is the preparation of fixed tissue.
What is an object that's a rectangular prism?
tissue box
Why would you use an irrigation staining technique opposed to direct application of iodine?
An irrigation staining technique is used to increase the contrast of soft tissue structures on an imaging study. This is done by injecting a contrast agent into the tissue. The contrast agent is typically iodine-based. Iodine-based contrast agents can be irritating to the tissue and can cause inflammation. This can lead to increased pain and discomfort for the patient. Additionally, iodine-based contrast agents can cause allergic reactions in some patients. An irrigation staining technique can help to minimize these side effects by diluting the contrast agent and evenly distributing it throughout the tissue. This can help to improve the comfort of the patient and increase the safety of the procedure.
How is an immune complex test done?
The method generally used for detecting immune complexes is examination of a tissue obtained by biopsy (removal and examination of tissue sample) and the subsequent use of different staining techniques with specific antibodies.
WHAT object is always common around muscle tissue?
Capillaries
How is a cell membrane related to tissue paper?
It is a soft object
What is uses of watch glasses?
They are useful for staining samples of biological tissue as only a small amount of stain needs to be added which will then sit in the centre of the watch glass.

How does the technique works of the direct immunofluroscence?
Immunofluorescence is a technique allowing the visualization of a specific protein or antigen in cells or tissue sections by binding a specific antibody chemically conjugated with a fluorescent dye such as fluorescein isothiocyanate (FITC). There are two major types of immunofluorescence staining methods: 1) direct immunofluorescence staining in which the primary antibody is labeled with fluorescence dye, and 2) indirect immunofluorescence staining in which a secondary antibody labeled with fluorochrome is used to recognize a primary antibody. Immunofluorescence staining can be performed on cells fixed on slides and tissue sections. Immunofluorescence stained samples are examined under a fluorescence microscope or confocal microscope
