Cleavage and Blastulation01:33

Cleavage and Blastulation

49.4K
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.

Fertilization01:38

Fertilization

88.7K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Overview of Exosomes

3.4K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

Area of Science:

  • Reproductive Biology
  • Cell Biology
  • Biochemistry

Background:

  • Embryo-maternal crosstalk is vital for successful pregnancy.
  • This communication begins at fertilization and continues throughout gestation.
  • Small extracellular vesicles (EVs) are key mediators of this interaction.

Purpose of the Study:

  • To review the role of small extracellular vesicles (EVs) in modulating embryo-maternal interactions.
  • To highlight the importance of EVs in early pregnancy events.

Main Methods:

  • Literature review focusing on small extracellular vesicles (EVs).
  • Analysis of studies investigating EV function in reproductive fluids.
  • Examination of molecular cargo within EVs (proteins, lipids, mRNA, miRNA).

Main Results:

  • Small EVs are present in oviductal and uterine fluids.
  • These EVs carry bioactive molecules influencing fertilization and early embryonic development.
  • Embryonic cells can internalize EVs from the mother, and embryo-derived EVs can affect maternal tissues.

Conclusions:

  • Extracellular vesicles play a significant role in embryo-maternal communication.
  • EVs are critical for successful fertilization and early embryonic development.
  • Understanding EV function offers insights into maintaining pregnancy.
