A Three-Dimensional Trophoblast Invasion Microfluidic Platform for Toxicological Screening

Area of Science:

• Biomedical Engineering
• Reproductive Biology
• Cell Biology

Background:

• Understanding human placental function is crucial for monitoring pregnancy health.
• Existing in vitro models do not fully replicate the in vivo placental microenvironment.
• Pregnancy stressors can impact placental cell responses, necessitating better research models.

Purpose of the Study:

• To develop an advanced in vitro model for studying human placental function.
• To create a three-dimensional (3D) microfluidic platform that mimics the placental microenvironment.
• To enable real-time evaluation of trophoblast invasion and cell interactions.

Main Methods:

• Utilized a three-dimensional (3D) polydimethylsiloxane (PDMS) microfluidic platform.
• Engineered a cellular barrier to establish a chemical gradient.
• Modeled a heterocellular placental microenvironment to observe trophoblast invasion.

Main Results:

• Successfully created a 3D microfluidic model of human trophoblast invasion.
• Demonstrated the formation of a cellular barrier mimicking placental tissue.
• Enabled real-time observation of trophoblast cell invasion and heterocellular interactions.

Conclusions:

• The developed PDMS microfluidic platform effectively models the human placental microenvironment.
• This model facilitates the study of trophoblast invasion and cell-cell interactions.
• It offers a valuable tool for understanding placental responses to pregnancy stressors.
