Researchers create ‘super stem cells’ that could improve fertility treatment
In a new study, researchers have successfully created stem cells that are better at developing into other cell types, like a younger, fitter version of themselves – by changing their diet. These stem cells are better than normal stem cells at creating specialised cells like liver, skin or nerve cells, which is a core trait of stem cells.
Stem cells are fundamental and unique cells in our bodies, that can replicate themselves and evolve into other, specialised cell types like liver, skin or nerve cells in a process known as differentiation. Embryonic stem cells (ESCs) are grown from an embryo and maintained in a dish. These cells can be developed into specialised cell types in a dish.
In the future, researchers believe that stem cells can be used for developing new treatments that replace or repair damaged tissues and organs or to restore functions that have been lost due to diseases or damages. This is known as regenerative medicine.
“We show that by changing their diet, the stem cells can rejuvenate and turn into ‘super stem cells’. It forces them to metabolise their energy in a different way than they normally would, and that process essentially reprograms the stem cells. The net result is that they behave like they are from an earlier stage of development, which enhances their ability to develop, or differentiate, into other types of cells,” said first author Robert Bone, assistant professor at the Novo Nordisk Foundation Center for Stem Cell Medicine, also known as reNEW.
Specifically, the researchers, from the University of Copenhagen, changed what type of sugar the stem cells have available in the medium they grow in. The cells use the sugar to generate energy.
“What is really striking is that they’re not just better at differentiating, but they stay fit and keep healthy much better over time compared to stem cells in standard culture conditions. And it is done with a relatively simple method,” says corresponding author Joshua Brickman, Professor at reNEW.
There are a many potential future usages of ‘super stem cells’, Joshua Brickman points out: “Given that we now have a simple means to rejuvenate cells, we want to investigate how this trick could work on a variety of cell types. For example, can we use this diet to revitalise liver or heart cells and use them to treat patients with congestive heart failure or liver cirrhosis? Perhaps we could use this trick to regenerate ageing cells and treat diseases such as Parkinson’s disease, osteoporosis or diabetes.”
One area the researchers are interested in is fertility treatment, specifically IVF. It turns out that the ‘super stem cells’ are good at producing a certain type of tissue that forms during early embryonic development and which is important for successful IVF treatment.
“One of the things that the ‘super stem cells’ seem to be better at making is a cell lineage that becomes something called the yolk sac. Previous research has found that the formation of yolk sac in embryos cultured in a dish is very important for their ability to implant and become successful pregnancies,” said Bone.
“We hope to improve IVF technology by developing a culture for IVF that uses the same metabolic process. Hopefully, it can be used as part of the embryo culture regime that they use in the clinic to improve success rates of implantation,” Brickman added.

IVFmicro raises £3.5m to boost IVF success
IVFmicro has raised £3.5m to advance its microfluidic device designed to improve IVF success rates in routine clinic use.
The Leeds-based spinout from the University of Leeds, founded in 2024, aims to increase the quality and number of embryos in an IVF cycle.
IVF, or in vitro fertilisation, combines eggs and sperm in a lab before transferring embryos to the womb. A microfluidic device is a chip with tiny channels that move very small volumes of fluid.
The company says its device could raise the number of viable embryos available for transfer and the likelihood that an embryo will implant.
Currently, IVF leads to a successful pregnancy in about 30 per cent of cases for women under 35. A single cycle typically costs around £5,000 in the UK.
“My career has focused on understanding the reproductive biology of eggs and embryos, how they develop and, crucially, why things sometimes go wrong,” said IVFmicro co-founder and scientific director Helen Picton.
“At IVFmicro, we are harnessing years of research into reproductive biology to create a practical, accessible solution that can improve outcomes for patients undergoing fertility treatment. Our goal is to make IVF more effective, more predictable, and ultimately more hopeful for those striving to start a family.”
The investment was led by Northern Gritstone, with support from Innovate UK’s Investment Partnership Programme.
“IVFMicro is a brilliant example of the world-class innovation emerging from the Northern Arc’s universities, combining scientific excellence with a clear commercial vision to tackle the societal challenge of infertility,” said Northern Gritstone chief executive Duncan Johnson.
“Millions worldwide require fertility treatment, but new solutions are needed to overcome the high costs involved and low success rates. We are especially proud that IVFMicro’s journey has been supported through our NG Studios programme and our Innovation Services, which exist to help founders like Virginia and Helen turn pioneering research into real-world impact.”

University of Leeds IVF spinout raises £3.5m
University of Leeds IVF spinout IVFmicro has raised £3.5m in pre-seed funding.
The investment is led by Northern Gritstone, with support from Innovate UK Investor Partnerships Programme, and will be used by IVFmicro for its next verification and validation phase, leading to trials on human embryos in fertility clinics.
Helen Picton is scientific director and co-founder of IVFmicro.
She said: “My career has focused on understanding the reproductive biology of eggs and embryos, how they develop and, crucially, why things sometimes go wrong.
“At IVFmicro, we are harnessing years of research into reproductive biology to create a practical, accessible solution that can improve outcomes for patients undergoing fertility treatment.
“Our goal is to make IVF more effective, more predictable, and ultimately more hopeful for those striving to start a family.”
Globally, 1 in 6 couples will face fertility issues, yet IVF success rates are suboptimal, with only 25-30 per cent succeeding in women under 35 years of age.
This is due in part to limitations of the embryo culture process, which typically involves repetitive handling, subjective selection of the best embryo, and the expense of highly skilled operators.
IVF is an expensive process, costing on average £5,000 for a patient in the UK for one cycle, accompanied by long NHS waiting lists that have selective criteria.
IVFmicro provides the first microfluidic device (a device for safely managing embryo culture and handling with very small amounts of nutrient-rich fluid) that can be used in any IVF treatment cycle.
This precision-engineered solution improves both the number of viable embryos available for transfer and the likelihood that an embryo will implant and result in a pregnancy.
IVFmicro provides a 10-15 per cent improvement in embryo quality and quantity, a significant leap that increases the potential to fall pregnant.
IVFmicro was founded in 2018 by Virginia Pensabene, Ph.D, and Helen Picton, Bsc, Ph.D., both professors at the University of Leeds.
Pensabene has published scientific advancements in microfluidics and brings her technical and scientific expertise to the product design.
Picton is a non-clinical expert in female reproductive biology and embryology, and has generated over £8m in research grant income.
IVFmicro recently took part in the NG Studios life sciences programme, which supports pre-seed life science businesses, and is delivered by accelerator KQ Labs, the Francis Crick Institute, and Northern Gritstone.
Virginia Pensabene, CEO and co-founder, IVFmicro, said: “As a biomedical engineer, I began exploring the potential of this technology in 2017, when Helen and I first met at the University of Leeds.
“From the start, our goal was to translate our research into a real solution for patients.
“Thanks to the combination of grant funding and Northern Gritstone’s support — both through investment and its innovation programmes — we have been able to grow our team in Leeds and take a major step toward bringing this precision-engineered IVF solution to market.”
