Could Epigenetic Reprogramming Revolutionize Bone Marrow Transplants?
New Study Explores Use of RNA-Based Therapy to Rejuvenate Aged Stem Cells
A groundbreaking study is underway to investigate the potential of epigenetic reprogramming to enhance the effectiveness and accessibility of bone marrow transplants. Led by researchers at Turn Biotechnologies, the research leverages a unique mRNA-based therapy called ERA™ to rejuvenate aging bone marrow stem cells.
The Challenge: Comrades in Arms Against Aging and Disease
As we age, our bone marrow becomes less efficient at producing healthy blood cells. This can impact our immune system’s ability to fight off infections and diseases.
Furthermore, aging bone marrow cells can accumulate changes in their DNA known as clonal hematopoiesis. These changes can be a precursor to the development of leukemia, posing a significant health risk.
Bone marrow transplants offer a lifeline for patients with blood cancers and other serious conditions. However, the effectiveness of these treatments depends heavily on the age and health of the donor cells. Younger donor cells generally result in better outcomes.
Unfortunately, a limited number of younger donors are available, highlighting the need for novel approaches to enhance donor cell quality.
A Promising Solution: ERA™ Therapy Offers a New Hope
Turn Bio’s innovative ERA™ therapy takes a targeted approach to combat the effects of aging in veteran bone marrow stem cells. This RNA-based approach aims to restore the cells’ youthful functionality, potentially unlocking a new era of more effective and accessible transplants.
The Study: Evaluating ERA™’s Potential
“This study conducts a comprehensive evaluation of ERA™ therapy’s ability to rejuvenate bone marrow stem cells,” said Timothy Olson, MD, PhD, principal investigator of the study.
“By reversing the effects of aging, we hope to make bone marrow transplants more effective and available to a broader range of patients,” he added.
The year-long study will use a proven mouse model to assess the effectiveness of ERA™ therapy. Bone marrow cells from mice will be treated with ERA™ and then transplanted into irradiated mice with similar genetic backgrounds.
The researchers will closely monitor the transplanted cells’ performance, evaluating their ability to generate healthy blood cells and contribute to the overall well-being of the recipient mice.
Unlocking a Brighter Future
“We firmly believe that this study has the potential to revolutionize bone marrow transplantation,” said Anja Krammer, CEO of Turn Bio.
“It represents a significant milestone for our company, demonstrating the vast potential of our technology not just for individual therapies but for addressing a range of age-related health challenges.”);
The findings of this innovative study could pave the way for a new era in medicine, enabling us to effectively treat a wider range of patients with shorter wait times and improved clinical outcomes.
Not only could this research unlock more effective and accessible bone marrow transplants, but it holds vast implications for combating other age-related diseases.

## Could Epigenetic Reprogramming Revolutionize Bone Marrow Transplants?
**(Opening music)**
**Host:** Welcome back to the show. Today, we’re delving into cutting-edge research that could change the face of bone marrow transplants. Joining us is Dr. [Guest Name], a leading expert in [Guest’s area of expertise]. Dr. [Guest Name], thank you for being here.
**Dr. [Guest Name]:** It’s a pleasure to be here.
**Host:** Let’s start with the basics. Why are bone marrow transplants so crucial, but also facing challenges?
**Dr. [Guest Name]:** Bone marrow transplants are life-saving treatments for many blood cancers and diseases. They provide healthy stem cells that rebuild a patient’s blood system. However, the effectiveness hinges on the quality of the donor cells.
As we age, our bone marrow naturally produces fewer healthy blood cells, and this can make older donor cells less effective [[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC8110674/)]. This limitation in younger donors is a serious challenge.
**Host:** So, what’s the solution?
**Dr. [Guest Name]:** That’s where epigenetic reprogramming comes in. Scientists at Turn Biotechnologies are developing a groundbreaking therapy called ERA™ that utilizes mRNA to rejuvenate aging bone marrow stem cells.
Essentially, ERA™ targets the epigenetic markers that are altered with age, effectively “reprogramming” the cells to behave more like younger, healthier stem cells.
**Host:** That sounds incredibly promising. What are the potential benefits of this approach?
**Dr. [Guest Name]:** The potential impact is huge. ERA™ could potentially increase the pool of eligible donors, allowing us to use bone marrow from older individuals more effectively.
**Host:** This could be a game-changer for patients in need of transplants. How far along is this research, and what are the next steps?
**Dr. [Guest Name]:** Turn Bio is actively conducting preclinical studies, and the initial results are very encouraging. They’re hoping to move into clinical trials soon. This is a rapidly evolving field, and we’re all eagerly awaiting the outcomes of these trials.
**Host:** Dr. [Guest Name], thank you so much for shedding light on this exciting development. This research holds immense promise for improving the lives of countless individuals.
