The creation of human organs in a laboratory could become a reality at a UAE-backed research centre in London that is adapting 3D printing to create functioning tissue.
A new technique from the Zayed Centre for Research into Rare Disease in Children involves 3D bio-printing near or around microscopic organs, grown from stem cells in the lab and known as organoids.
“These 3D structures then act as barriers to guide the growth of the mini organs in specific directions or patterns”, Dr Giovanni Giobbe, the co-lead author of the research, told The National.
Using the 3D printed structures, the researchers were able to guide the growth of organoids into specific shapes that they could then visualise using a high specification microscope
“Precise control over cell development is of great importance in various fields, such as regenerative medicine, disease modelling and drug testing,” said Dr Giobbe.
“The ability to make cells into a specific shape or type allows the creation of engineered tissues and organs, providing potential solutions for organ transplantation and regenerative therapies.”
The centre, which is part of the Great Ormond Street Hospital for Children, aims to break new ground in understanding and treating rare childhood diseases.
It was partly born from a £60 million ($82.6 million) donation made by Sheikha Fatima, Mother of the Nation, in 2014. Honouring her husband, the UAE Founding Father, the late Sheikh Zayed bin Sultan Al Nahyan, the centre's name reflects their commitment to pioneering medical care for children.
Now in its fourth year, the centre is making waves in genetic therapy and tackling health crises like Covid-19, but it is also looking to the future with 3D bio-printing.
Dr Giobbe describes the technique as “an advanced technology where scientists and researchers can create three-dimensional structures using biological materials”.
“It involves carefully depositing these materials layer by layer in a specific pattern to build complex microscopic 3D shapes,” he said.
The technique could transform the landscape of regenerative medicine by developing organoids.
The power of precision
Scientists from the Great Ormond Street Hospital Biomedical Research Centre and the University of Padova, Italy are at the forefront of the field.
Their research, published in the Nature Communications journal, provides new insight into how 3D bio-printing can control the shape, activity and direction of tissue growth.
The study reveals the successful development of a technique to create solid structures within a pre-existing gel, controlling the growth pattern in real time.
Cells in the organoid develop in a precise, controlled manner, offering new understanding of malformations that occur in early pregnancy.
The benefits of 3D bio-printing for organ research and regenerative medicine include everything from “the creation of accurate organ models for drug testing, personalised organ replacement and regenerative therapies”, Dr Giobbe said.
The technology promises to help create more accurate models of diseases and develop biologically accurate “patches” for living organs.
This involves creating specialised tissues using living cells to repair or replace damaged organ parts, the researchers said.
Dr Giobbe said the motivation for exploring the technique was so that structures seen in the body could be replicated.
“The overall aim of our research was to develop a novel method to control and direct the growth of biological tissues to better understand the importance of geometry in organ development,” he said.
Zayed Centre for Research
The centre is home to cutting-edge research in organoid science in partnership with Great Ormond Street, the hospital's charity and University College London.
The team acknowledges that a number of challenges must be overcome before 3D bio-printing can be used to create fully functioning organs, such as the complexity of organs, preventing immune rejection, improving production time and scalability, ethical considerations and cost-effectiveness.
The centre has a diverse range of specialities, including cardiology, respiratory medicine, dermatology, immunology and neonatal and paediatric surgery. Organoids are an area of particular promise.
These tissues have typically grown in an uncontrolled manner, unable to mimic the complex structure of natural organs. But 3D bio-printing offers a solution to this.
The “groundbreaking technology holds the potential to revolutionise medicine,” Dr Giobbe said.
The UAE's vision: A global 3D printing capital
The UAE aims to be a global leader in 3D printing technology, with an emphasis on medical uses. The Dubai Health Authority aims to produce artificial limbs using 3D printing for less than Dh400 by 2025.
The value of 3D printed medical products in Dubai is projected to reach Dh1.7 billion by 2025.

Navdeep Suri, India's Ambassador to the UAE
There has been a longstanding need from the Indian community to have a religious premises where they can practise their beliefs. Currently there is a very, very small temple in Bur Dubai and the community has outgrown this. So this will be a major temple and open to all denominations and a place should reflect India’s diversity.
It fits so well into the UAE’s own commitment to tolerance and pluralism and coming in the year of tolerance gives it that extra dimension.
What we will see on April 20 is the foundation ceremony and we expect a pretty broad cross section of the Indian community to be present, both from the UAE and abroad. The Hindu group that is building the temple will have their holiest leader attending – and we expect very senior representation from the leadership of the UAE.
When the designs were taken to the leadership, there were two clear options. There was a New Jersey model with a rectangular structure with the temple recessed inside so it was not too visible from the outside and another was the Neasden temple in London with the spires in its classical shape. And they said: look we said we wanted a temple so it should look like a temple. So this should be a classical style temple in all its glory.
It is beautifully located - 30 minutes outside of Abu Dhabi and barely 45 minutes to Dubai so it serves the needs of both communities.
This is going to be the big temple where I expect people to come from across the country at major festivals and occasions.
It is hugely important – it will take a couple of years to complete given the scale. It is going to be remarkable and will contribute something not just to the landscape in terms of visual architecture but also to the ethos. Here will be a real representation of UAE’s pluralism.

Moral education needed in a 'rapidly changing world'
Moral education lessons for young people is needed in a rapidly changing world, the head of the programme said.
Alanood Al Kaabi, head of programmes at the Education Affairs Office of the Crown Price Court - Abu Dhabi, said: "The Crown Price Court is fully behind this initiative and have already seen the curriculum succeed in empowering young people and providing them with the necessary tools to succeed in building the future of the nation at all levels.
"Moral education touches on every aspect and subject that children engage in.
"It is not just limited to science or maths but it is involved in all subjects and it is helping children to adapt to integral moral practises.
"The moral education programme has been designed to develop children holistically in a world being rapidly transformed by technology and globalisation."
