Cell Lines

8.3K
A cell line is a population of cells grown in vitro that can be subcultured over several generations. Normal cells cease to divide after a certain number of cell divisions, a process known as replicative senescence. This number, called the Hayflick limit, was conceptualized by Leonard Hayflick in 1961 when he observed that fetal cells grown in culture could only divide 40-60 times. This limit is due to the shortening of the telomeres during each round of cell division, preventing cell division...

Polytene Chromosomes

9.3K
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...

Area of Science:

  • Cytopathology
  • Oral Medicine
  • Diagnostic Accuracy

Background:

  • Cytological artifacts can lead to erroneous diagnostic results in routine laboratory practices.
  • Familiarity with artifacts is essential for accurate cytological interpretation.

Purpose of the Study:

  • To investigate the impact of delayed fixation on oral cytosmear interpretation.
  • To analyze morphological changes caused by extraneous factors in oral cytosmears.

Main Methods:

  • Prospective study involving 66 dental students.
  • Papanicolaou and Hematoxylin and Eosin stained oral smears analyzed.
  • Variations included delayed fixation (room temp, 60-70°C, 3-4°C) and contaminants.

Main Results:

  • Delayed fixation initially affected cytoplasm, then nucleus, leading to degeneration over time.
  • Higher temperatures accelerated degenerative changes compared to lower temperatures.
  • Extraneous factors introduced notable morphological discrepancies.

Conclusions:

  • Cytologists must recognize delayed fixation artifacts and contaminants for accurate interpretation.
  • Knowledge of these factors aids in better prognosis and therapeutic decisions.
  • Ensuring proper sample handling is vital for reliable cytosmear diagnosis.
