Existing drugs that delay preterm labour can’t be used for long periods because of their effects on the blood vessels of the womb and the placenta. To help find better treatments, Prof Michael Taggart and his team have conducted a detailed molecular study of the womb muscle tissue and blood vessels in mother and baby. Their research will help scientists find better treatments, with fewer side-effects, to stop babies from being born too soon.

The challenge

For many pregnant mothers who into preterm labour, there is no obvious explanation why. There are drugs which can briefly delay labour by relaxing the muscle tissue in the womb, but these drugs also come with risks to both mother and baby. This is because, as well as relaxing muscle tissue, they also relax the blood vessels in the womb and baby’s placenta. This can cause problems with blood pressure and reduce blood supply to the baby.

We need to find better treatments to pause preterm labour that are less risky for mother and baby.

The project

Prof Michael Taggart hopes to help find treatments to delay labour by stopping the womb muscle tissue contracting, without affecting the mother’s or baby’s blood vessels.

A major barrier to this is that we don’t fully understand the differences, at a molecular level, between the three key tissues involved – muscle tissue in the womb, blood vessels in the womb, and blood vessels in the baby’s placenta.

In this project, which ended in December 2023, Prof Taggart and his colleagues used state-of-the-art techniques to examine the differences between these three tissues. In a collection of tissue samples donated by pregnant women, they assessed the amounts of nearly 7,000 proteins and 20,000 genes. Some of this work was carried out on individual cells, to see if different types of cells in these tissues have different roles.

Their detailed work has provided a new understanding of the molecules that distinguish womb muscle tissue from the mother’s and baby’s blood vessels. This will help scientists to find drugs that can specifically target muscles to stop contractions, while leaving the blood vessels unaffected.

What difference will this project make?

We need to find better treatments that can help delay preterm labour, as current drugs have too many side-effects to be used for long periods of time. This research has provided the foundational knowledge needed to identify new or existing drugs that can target specific molecules in the womb muscle. The team hope that these drugs could be ready to test in clinical trials within three to seven years.

The hope is that this could eventually lead to new treatments that will help stop babies from being born too soon.

The funding from Borne and Action Medical Research has been transformative for our pregnancy-related research. It has enabled us to use state-of-the-art technology to reveal molecules that are enriched in specific tissues of the uterus and placenta. This opens new avenues for the development of much-needed new drug treatments for women with pregnancy complications such as preterm labour.

Testing the long-term health impact of a new drug to prevent preterm birth

Prof Stephen Lye and colleagues have identified a drug which can prevent preterm birth in animal studies. In this project, the team are investigating whether the drug improves the long-term health of newborns. The evidence generated promises to enable the team to test the drug in human clinical trials. If successful, this may one day provide a new option to prevent some babies from being born too soon.omega-3 fatty acids in the blood. The evidence generated could change global food and health policy, preventing preterm births and improving the health of mothers and babies worldwide.

The FAB study – testing an omega-3 oil supplement to prevent preterm birth

Previous research has suggested that omega-3 fatty acids may prevent preterm birth, but clinical trials of supplements have had mixed results. The FAB study is testing the benefits of a particular supplement in a group of women in India with low levels of omega-3 fatty acids in the blood. The evidence generated could change global food and health policy, preventing preterm births and improving the health of mothers and babies worldwide.

Investigating how immune cells help the placenta to implant correctly

Dr Viki Male and her team have found that immune cells called uNK1 cells may play a key role in helping the placenta implant into the womb correctly. In this project, Dr Male is studying tiny protein-filled packages inside uNK1 cells, to understand exactly how they might support placental implantation.
