Cerebral Palsy-Afflicted Toddler Could Walk Again, Thanks to Transfusion from Baby Brother’s Blood

Two-year-old Isla Duffy, who has cerebral palsy, may have the opportunity to walk again thanks to a remarkable stem cell treatment that utilizes blood from her six-month-old brother Leo’s umbilical cord. Isla will undergo the treatment at Duke University Hospital in North Carolina in August.

Cerebral palsy is caused by damage to the developing brain, and it can manifest in various ways, including impaired movement, spasticity, and poor coordination. While there is no known cure for cerebral palsy, stem cell therapy is a promising area of research that may help to alleviate some of the symptoms associated with the condition.

Stem cells found in cord blood and other sources have the ability to differentiate into a variety of cell types, including nerve cells. This makes them potentially useful in regenerative medicine and for treating conditions like cerebral palsy.

Preliminary studies on the use of cord blood therapy for treating cerebral palsy have shown promising results, with some patients experiencing improvements in motor function and reduced muscle spasticity. However, more research is needed to fully understand the potential of stem cell therapy for this condition and to establish safe and effective protocols for treatment.

Isla Duffy will travel to Duke University Hospital in North Carolina, US, in July to undergo stem cell treatment using her six-month-old baby brother Leo’s umbilical cord blood. Cord blood is rich with stem cells – which have amazing regenerative properties that can be used to treat many different cancers, immune deficiencies and genetic disorders. Little Isla was deprived of oxygen and suffered a seizure shortly after birth in 2021.

In addition to cerebral palsy, stem cell therapy has shown promise in treating a range of other genetic disorders, immune system deficiencies, and cancers. While stem cell therapy is still considered experimental in many cases, ongoing research is working to further understand its potential and to develop safe and effective treatments for a variety of conditions.

Emily and Sim, Isla’s parents, were thrilled to learn that their daughter is eligible for this treatment using Leo’s cord blood. As they aim to raise over $30,000 for the treatment and essential physiotherapy, the Duffy family is hopeful that this life-changing treatment will enable Isla to walk again, and they are grateful for the potential of stem cell research in providing new treatments for cerebral palsy and other conditions.
Emily, Isla’s mother, expressed her relief in a social media post, noting that finding out Isla was eligible for the treatment was a massive relief for their family. She explained that the treatment required at least a 50% genetic compatibility, and they were fortunate to find out that Leo was a good match for his older sister.

Emily and her husband Sim are optimistic about the potential of stem cell treatment to improve Isla’s mobility and quality of life. As their family works to raise funds for the treatment and associated physiotherapy, they are grateful for the support they have received and hopeful about the future.

Emily shared her high aspirations for the treatment, as having a child with cerebral palsy often means being told there is no treatment or cure. She expressed her hope that a successful treatment could allow Isla to develop exponentially and potentially learn to talk, a milestone she may have never been able to reach otherwise. The treatment could also help Isla walk much faster, as currently she is unable to sit independently, crawl or walk due to the limitations of cerebral palsy.

Additionally, Isla is non-verbal and likely has autism, which makes communication with her even more challenging. Despite these obstacles, Isla enjoys books, playing outside, and interacting with animals, and longs to be able to do what typical two-year-olds can do. Her parents are hopeful that the stem cell treatment will lead to significant improvements in her mobility and communication, and allow her to truly experience the joys of childhood.
Isla’s parents are grateful for the bond that has developed between Leo and Isla and hopeful that the treatment will help Isla enjoy new experiences like playing with other children, something she has been limited in doing due to her condition. They aim to travel to Duke University Hospital this summer for Isla’s self-funded treatment, which costs $15,000.

As Sim notes, cerebral palsy is the most common motor disability in children, affecting 1 in 400 in the UK, and while there is currently no cure for the condition, clinical trials are ongoing to find new ways to treat it. It has been a long and difficult journey for the family, but they are optimistic about the potential of stem cell treatment to improve Isla’s quality of life and hope that Isla’s story can inspire further research and treatment options for this common and debilitating condition.
Sim highlights that the UK is behind in terms of stem cell research compared to other countries, but universities and hospitals worldwide are conducting trial treatments as scientists continue to explore the potential of regenerative medicine.

He emphasizes that the US is strict about matching the blood type and ensuring genetic compatibility between the donor and patient for such treatments. The Duffy family made sure to save Leo’s cord blood with these requirements in mind when they decided to have another child, which has enabled Isla to undergo this promising treatment.

The Duffys’ story is a powerful example of the potential of stem cell therapy and the importance of genetic compatibility in achieving successful outcomes. The use of cord blood stem cells from Isla’s younger brother is a good example of how stem cell therapy can use these regenerative cells to treat genetic disorders and other medical conditions.

Given the increasing prevalence of cerebral palsy and the limited treatment options available, advances in stem cell therapy offer hope for patients and their families. More research is needed to fully understand the mechanisms underlying stem cell therapy and to establish safe and effective protocols for treatment.

However, as the Duffys’ story illustrates, stem cell therapy has the potential to provide new treatment options for those with cerebral palsy and other conditions, highlighting the importance of continuing to advance our understanding of stem cells and regenerative medicine.


Stem cells are undifferentiated cells that have the ability to differentiate into different types of cells in the body, such as nerve cells, muscle cells, and blood cells. This makes them an attractive candidate for regenerative medicine and treating diseases that involve damage to specific cell types.

There are different types of stem cells, including embryonic stem cells which are derived from embryos and adult stem cells which are found in various tissues in the body. The use of embryonic stem cells is controversial due to ethical concerns surrounding their extraction from human embryos. On the other hand, adult stem cells are generally considered less controversial, but they also have a more limited ability to differentiate into different cell types.

Stem cell treatments have shown promise in treating a variety of conditions, including spinal cord injuries, heart disease, and certain types of cancer. However, stem cell treatments are still experimental and their long-term effects are not well understood.

It is important for anyone considering stem cell treatments to thoroughly research the potential risks and benefits, and to discuss the options with a qualified healthcare professional. Stem cell clinics that offer unproven or untested treatments outside of clinical trials should be approached with caution.
Indeed, preserving cord blood is becoming an increasingly popular option for parents who want to ensure their children have access to potentially life-saving cells in the future. Cord blood contains a rich source of stem cells that can be used for various treatments, including regenerating damaged tissues and treating certain types of cancers.

To preserve cord blood, a process known as cord blood banking is used. It involves collecting the blood from the umbilical cord after birth and storing it in a specialized facility that can maintain the integrity of the cells for years to come.

However, cord blood banking can be expensive, with some estimates putting the cost at several thousand dollars for the initial collection and storage, as well as ongoing maintenance fees. This cost can be a barrier for many families who may not have the resources to invest in this option.

Nonetheless, the potential benefits of cord blood banking and the use of stem cells in medical treatments have prompted many families to consider this option. The decision to bank cord blood is a personal one that should be based on thorough research and discussion with qualified healthcare professionals.
Stem cells are considered a promising therapy for treating a variety of diseases and conditions, including type 1 diabetes, spinal cord injuries, and heart disease. One of the reasons stem cells are so effective is because of their unique properties that allow them to regenerate and repair damaged tissues.

Self-renewal is one of the key attributes that provides stem cells with their regenerative abilities. This means that stem cells can continuously divide and produce identical copies of themselves while maintaining their undifferentiated state. This characteristic enables the stem cell population to remain stable in tissues and organs throughout an organism’s life.

Potency, or the ability to differentiate into various cell types, is another critical attribute of stem cells. Stem cells can differentiate into many different cell types and therefore have the potential to repair damaged tissues and organs.

Cord blood is rich with stem cells – which have amazing regenerative properties that can be used to treat many different cancers, immune deficiencies and genetic disorders. Little Isla was deprived of oxygen and suffered a seizure shortly after birth in 2021.

Stem cells are also highly sensitive to their environment, or the stem cell niche. This specialized microenvironment provides signals that regulate stem cell behavior, including the balance between self-renewal and differentiation. The stem cell niche can help to regulate tissue regeneration and repair.

Additionally, stem cells can divide asymmetrically, producing two daughter cells with different fates. One daughter cell remains a stem cell, while the other differentiates into a specialized cell type. This allows stem cells to generate specialized cells while still maintaining their population.

Despite the immense potential of stem cell therapy, much research is needed to fully understand their mechanisms of action and potential applications. Efforts are ongoing to develop safe and effective stem cell therapies for a variety of diseases and conditions.
One of the major ethical concerns surrounding stem cell research is the use of embryonic stem cells, which are derived from embryos that are typically discarded after in vitro fertilization procedures. This has raised questions about the moral status of embryos and the ethics of using them for medical research. However, many researchers argue that these embryos would have been discarded anyway and that the potential benefits of stem cell research outweigh the ethical concerns.

Another technical challenge of stem cell research is the potential for immune rejection. Stem cells derived from a different individual may be recognized as foreign by the recipient’s immune system and attacked, potentially leading to transplant rejection. To address this, researchers are developing techniques to create stem cells that are genetically matched to the recipient or using immune-suppressing medications to prevent rejection.

Despite these challenges, there are many ongoing efforts to harness the potential of stem cells in regenerative medicine and tissue engineering. In recent years, scientists have made significant progress in the development of induced pluripotent stem cells (iPSCs), which can be generated directly from adult cells and can potentially avoid the ethical concerns associated with embryonic stem cells.

Additionally, researchers are working to develop new methods for delivering stem cells to damaged tissues, including using scaffolds and 3D printing technologies, which could enable the creation of custom-made tissues and organs with minimal risk of immune rejection.

Overall, the potential benefits of stem cells in regenerative medicine and tissue engineering are enormous, and ongoing research is working to address the ethical and technical challenges associated with this field.
