Insights

Transferring cells from one cytologic smear to multiple slides allows for extensive immunocytochemical staining on limited samples. This method preserves cell morphology and provides reliable results for diagnosing various cancers.

Area of Science:

  • Cytopathology
  • Immunohistochemistry
  • Diagnostic Pathology

Background:

  • Immunocytochemical studies on cytologic specimens are often constrained by the limited number of diagnostic cells available per slide.
  • Performing multiple stains on a single smear can deplete the cellular material, hindering comprehensive analysis.

Purpose of the Study:

  • To evaluate the efficacy of transferring cells from a single cytologic smear to multiple slides.
  • To determine if this cell transfer technique allows for a battery of immunocytochemical stains on limited material without compromising diagnostic quality.

Main Methods:

  • Cells were transferred from single smears of four effusions and five fine needle aspirates to multiple slides.
  • Immunocytochemical staining was performed on the transferred cells using common diagnostic antibodies.
  • Cell morphology and background staining were assessed.

Main Results:

  • Immunostaining yielded expected results for most antibodies used in diagnostic pathology.
  • Cell transfer preserved the morphology of the cytologic specimens.
  • Low background staining was generally observed after cell transfer.

Conclusions:

  • Cell transfer is an effective method for performing multiple immunocytochemical stains on limited cytologic material.
  • This technique may enhance the cytologic diagnosis of various malignancies, including lymphoma, neuroendocrine neoplasms, and adenocarcinomas of the prostate and breast.

Facilitated Transport01:19

Facilitated Transport

The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In  facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...

Social Facilitation01:04

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Facilitated Diffusion01:16

Facilitated Diffusion

The plasma membrane, a critical structure in cellular biology, houses an array of transporters, or carrier proteins, interspersed within its lipid bilayer. These proteins play a crucial role in solute transport through facilitated diffusion, a form of passive diffusion that uses transporters to move the molecules across the membrane.
In this process, substrates such as organic compounds and ions interact with a transporter on one side, triggering conformational changes in proteins that enable...

Ionic Bonding and Electron Transfer02:48

Ionic Bonding and Electron Transfer

Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.

Transfer RNA Synthesis02:36

Transfer RNA Synthesis

One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
