Cell Diversity01:13

Cell Diversity

3.2K
The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

Cells Coordinate Growth and Proliferation

4.5K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Zygotic Development And Stem Cell Formation

5.2K
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...

Distribution of Cytoplasmic Content

4.1K
Cytokinesis segregates a cell’s chromosomes and organelles into its daughter cells. Organelles divide and grow prior to cell division but cannot be synthesized de novo; therefore, cells must receive at least one copy of each organelle to survive. Currently, many of the details of how the organelles are distributed are not yet fully elucidated.
Distribution of cytoplasmic determinants
The cytoplasm contains various organelles, as well as salts, proteins, and water. The distribution of...

Overview of Cell-Cell Junctions

25.6K
The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and the extracellular matrix. Cell-cell junctions are specialized structures where the multi-protein complexes on one cell interact with the multi-protein complexes on another  cell. These cell junctions are classified  into three main types based on their function — occluding, anchoring, and gap junctions.
Occluding or Tight...

Differentiation of Common Myeloid Progenitor Cells01:15

Differentiation of Common Myeloid Progenitor Cells

3.2K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Area of Science:

  • Cell Biology
  • Parasitology
  • Microbiology

Background:

  • Multinucleated Giant Cells (MGCs) arise from cell fusion, observed in human infections.
  • MGC formation can also occur via endoreplication and abortive cell cycles, leading to polyploid cells.
  • MGC formation is a unique phenomenon in the protozoan parasite Entamoeba, not previously reported in other protozoa.

Purpose of the Study:

  • To investigate the phenomenon of MGC formation in Entamoeba.
  • To understand the mechanisms and implications of MGC formation in Entamoeba.
  • To explore MGCs as a potential survival strategy and virulence factor in Entamoeba.

Main Methods:

  • Observational studies of Entamoeba under various stress conditions.
  • Analysis of cell aggregation and fusion processes.
  • Examination of MGC presence in Entamoeba-induced infections.

Main Results:

  • Entamoeba forms MGCs through cell aggregation and fusion in response to osmotic and heat stress.
  • MGCs in Entamoeba exhibit increased resistance to stress and prolonged survival.
  • MGCs are found in inflammatory foci of amoebic liver abscesses, suggesting a role in pathogenesis.

Conclusions:

  • MGC formation in Entamoeba is a survival mechanism against adverse environmental conditions.
  • MGCs may enhance Entamoeba's resistance and virulence.
  • Studying Entamoeba MGCs offers insights into cell fusion and potential therapeutic targets.
