What is a cytospin used for?

A cytospin is obtained by employing centrifugal force to isolate, concentrate and deposit a monolayer of cells from a dilute cell suspension onto a circular area on a slide. The objective is to keep cells intact enabling the morphology of the cells to be examined.

What is cytospin test?

Comments: This test is a pathologist’s examination of an air-dried wright-stained slide prepared on a cytospin. A written interpretation by a pathologist is reported by computer. Specimens suspicious for malignancy should be confirmed with pap stained millipore cytology or tissue biopsy.

What is the role of cytology in Diagnosing?

Cytologic techniques, depending on the tumor location and type may be employed for primary diagnosis, prognosis, and prediction of tumor behavior as well as secondary/recurrent diagnoses, and may also be used for staging purposes.

What is a cytospin instrument?

The Cytospin centrifuge is a special purpose instrument designed to deposit cells evenly onto a glass slide. The instrument when used correctly produces a monolayer cell deposition in a defined area of the slide using centrifugal force.

What is the function of Cytocentrifuge?

A cytocentrifuge, sometimes referred to as a cytospin, is a specialized centrifuge used to concentrate cells in fluid specimens onto a microscope slide so that they can be stained and examined.

Can you cytospin fixed cells?

Simply re-suspend your cells in medium and add formaldehyde (1:10 producing a 4% solution of formalin). I recommend using ‘charged’ slides for your cytospins and I spin at 500rpm for 10 minutes. The remaining cell suspension can quite happily be stored in the fridge for 12 months+ and more cytospins made at any point.

What is CSF cytospin?

Description: Cytocentrifugation is a method of gentle and controlled centrifugation, that produces a monolayer of preserved, displayed cells (when present). These are flattened constructively on a slide, offering a more open nucleus and more visually interpretable nuclear material.

What is the indication of an impression smear?

Impression smears, like skin scrapings, are good for detecting the presence of inflammation, infectious organisms, and abnormal tissue cells.

What are the most important tools of cytology?

Aspiration cytology The most famous ones are FNA, fine needle aspiration biopsy (FNAB), and needle aspiration biopsy cytology (NABC). All of them mean the same thing; aspirating cellular material using a fine needle to make a diagnosis.

Can you fix cells overnight?

You can fix and then store/freeze cells to then stain and analyze later. However, it would not be a good idea to do this if you are interested in surface markers due to the possibility of the fixative denaturing the epitopes. For intracellular expression it is not a problem. Good Luck!

How is the cytospin technique used in cytology?

The cytospin technique can be used on any single cell suspensions of any source such as peripheral blood mononuclear cells (PBMCs), effusions, cerebral spinal fluid (CSF), bronchial lavages, fine-needle aspirates, culture cells, etc. In cytospins, single cell suspensions are spun onto a microscope slide by use of a cytocentrifuge.

How are single cell suspensions spun in a Cytospin?

In cytospins, single cell suspensions are spun onto a microscope slide by use of a cytocentrifuge. A cytocentrifuge spins cells at an angle, at low speeds, and accelerates and decelerates gradually. The fluid from the suspension is absorbed onto filter paper while the centrifuge is spinning.

Which is most sensitive to staining of cytospin cells?

EMA stained both the cytoplasm and the membrane of the cells. GLUT-1 stained the membrane of the cytospin cells and expression was highly sensitive in malignant cells. IMP3 stained the cytoplasm of the cytospin cells and expression was lowest in malignant cells.

How is cytology used to diagnose cancer?

This cytology method and subsequent staining of the resultant cells are a key component of diagnosis and screening of diseases such as cancer.
