O'Tierney-Ginn Placenta Lab

O'Tierney-Ginn Placenta Lab The O'Tierney-Ginn lab studies how the mom, baby and placenta "talk" to each other. The placenta is a fascinating organ. It's not cute like the kidneys.

In our lab, we study how a mother's diet, metabolism and body type (her nutritional profile) affects the growth and function of the placenta. It's the only organ that disposes of itself when it's no longer needed. The length of the placental capillaries combined is 32 miles. It is one of our most important organs, and the most poorly understood. It doesn't dance like the heart. But it's your fetus' best friend.

Excellent commentary by Dr. Diana Bianchi and colleagues regarding the inclusion (or lack thereof) of pregnant people and lactating people in the COVID-19 vaccine trials.

This Viewpoint from the National Institute of Child Health and Human Development emphasizes the need to use existing data sources and develop partnerships, infrastructure, and ethical and regulatory standards to generate data about the safety and efficacy of COVID-19 vaccination in pregnant...

Great piece on our favourite organ by Science Friday !

The placenta is the only organ that can be grown temporarily and then discarded—but it’s hard to study while it’s doing its job.

"Once a viral protein, the virus essentially morphed or evolved into what we now know as syncytin. This protein gives baby the ability to fuse cells into a wall — the placenta — that connects mom and baby but also keeps them separate."

When evolutionary biologists studied the protein involved in fusing placenta cells, it didn’t look like it came from human DNA. It looked like a virus.

Fascinating!!

Fascinating!!

Have you ever wondered why embroidery scissors are shaped like storks? Well, these scissors didn't actually start out as scissors, but as umbilical clamps. Sometimes, the clamps would be used with a set of forceps shaped like snakes. Why snakes? To symbolise the Rod of Asclepius, the Greek god of healing and medicine.

Between the 19th century and now, these little stork scissors have gone through some really big changes. In the past, most of them were between four and a half to six inches long, with their heads mounted at almost a 45-degree angle. The beaks were heavy clamps not meant to cut, but to restrict the blood flow before the umbilical was cut. Some even had little babies hidden inside the stork's beak that would appear when the clamps were opened.

The midwives began to use the scissors for needlework that they carried with them to work on during long waiting times when babies were being born.

Who knew these scissors had such a long history that started with delivering babies? The Smithsonian has a medical bag on display with a pair of stork scissors, in their American History Collection.
