Measuring oxytocin-driven contractions in lab-grown 3D uterine muscle
Quantitating Oxytocin-induced Contractility in Bioengineered 3D Human Myometrium
This project builds a lab-grown three-dimensional uterine muscle from patient cells to learn how different doses and durations of oxytocin cause contractions in people at term.

What this research studies
Researchers will grow a 3D human myometrium in the lab using smooth muscle cells taken from people delivering at term. They will expose the bioengineered tissue to varying oxytocin doses and durations and directly measure the force of contraction using organ-bath style methods. This aims to reproduce real muscle mechanics rather than relying on indirect collagen assays and to clarify how dose and exposure influence contractile response. The work could inform safer, more precise oxytocin use in labor and after birth.
Who could benefit from this research
Good fit: Ideal contributors are people delivering at term (≥37 weeks) who can consent to donate small myometrial tissue samples, for example during cesarean or planned abdominal delivery.
Not a fit: People who are not pregnant, who cannot donate tissue, or whose conditions are unrelated to uterine contractility are unlikely to benefit directly from this project.
Why it matters
Potential benefit: If successful, this could help clinicians choose oxytocin doses and timing that reduce unnecessary cesareans and postpartum bleeding.
How similar studies have performed: Previous organ-bath and cell-culture studies have measured uterine contractility, but creating a patient-derived 3D myometrium to directly measure force is novel and largely untested.
