Cleavage and Blastulation

Cleavage and Blastulation

After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

Zygotic Development And Stem Cell Formation

Zygotic Development And Stem Cell Formation

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...

Mitosis and Cytokinesis

Mitosis and Cytokinesis

In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome duplication, chromosome distribution to daughter cells, and finally, cell division. The cell cycle is tightly regulated by its regulatory systems as well as extracellular signals that affect cell proliferation.
The processes of the cell cycle occur over approximately 24 hours (in typical human cells) and in two major distinguishable stages. The...

Enlargement of the Plasma Membrane

Enlargement of the Plasma Membrane

Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

Cell Migration

Cell Migration

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Area of Science:

Cell biology
Developmental biology
Biochemistry

Background:

Cell fusion is essential for development, occurring in gamete fusion, muscle formation, bone development, and placental formation.
The specific molecules (fusogens) mediating these crucial fusion events remain largely unknown.
Understanding fusogens is key to deciphering fundamental biological processes.

Purpose of the Study:

To review and establish criteria for identifying genuine fusogens.
To propose a scoring system for assessing protein fusogenicity.
To compare different families of candidate fusogens and analyze current fusion models.

Main Methods:

Literature review of cell fusion processes and candidate fusogens.
Application of five established gold standards for fusogen identification.
Comparative analysis of developmental, viral, and intracellular fusogen families.
Evaluation of existing membrane fusion models.

Main Results:

Defined five gold standards for rigorous fusogen identification.
Developed a numerical scoring system to quantify fusogenicity.
Compared various candidate fusogen families, including developmental and viral types.
Analyzed current mechanistic models of membrane fusion.

Conclusions:

A standardized approach using defined criteria and scoring is necessary for accurate fusogen identification.
Further research is needed to elucidate the precise mechanisms of developmental cell fusion.
This review provides a framework for future studies investigating membrane fusion and its molecular players.
