Summary

Leukemia inhibitory factor (LIF) is crucial for human reproduction, particularly for successful embryo implantation. Lower LIF levels are linked to unexplained infertility, highlighting its role in establishing pregnancy.

Area of Science:

  • Reproductive Biology
  • Molecular Endocrinology
  • Human Reproduction

Background:

  • Leukemia inhibitory factor (LIF) is a cytokine with known roles in cell differentiation and survival.
  • Its specific functions and implications in human reproductive processes require detailed elucidation.

Purpose of the Study:

  • To comprehensively review the clinical findings, expression patterns, molecular interactions, and clinical significance of LIF in human reproduction.
  • To understand the role of LIF in the context of implantation and early pregnancy establishment.

Main Methods:

  • Systematic review of published scientific literature.
  • Analysis of clinical data and experimental findings related to LIF expression and function.

Main Results:

Related Experiment Videos

  • LIF expression in the endometrium is cyclical, peaking during the implantation window.
  • Reduced LIF levels are observed in women with unexplained infertility, both in uterine fluid and endometrial explants.
  • LIF signaling, via LIF receptor and gp130, influences trophoblast differentiation and implantation.

Conclusions:

  • LIF plays a critical role in successful embryo implantation and the establishment of pregnancy.
  • Dysregulation of LIF may contribute to infertility, suggesting potential therapeutic targets.
