The ISSCR honors Alexander Meissner with the 2026 ISSCR Momentum Award for exceptional work in developmental and stem cell epigenetics

Honorable mention winners recognized for significant contributions to stem cell science

2026-03-03

(Press-News.org) The International Society for Stem Cell Research (ISSCR) is pleased to announce that Alexander Meissner, Director at the Max Planck Institute for Molecular Genetics, Germany, has been named the recipient of the 2026 ISSCR Momentum Award. The award, supported by BlueRock Therapeutics, recognizes an investigator whose sustained scientific contributions continue to shape and accelerate the field of stem cell research. Dr. Meissner will present his work during ISSCR 2026 taking place in Montréal, Canada on 8-11 July 2026.

For nearly two decades, Meissner has been a leading force in developmental and stem cell epigenetics. His work addresses a central question in biology: how cell identity is established, maintained, and reprogrammed. Through pioneering genomic and epigenomic studies, he defined key mechanistic steps underlying somatic cell reprogramming and pluripotency, helping to establish the conceptual and technical foundations of induced pluripotent stem cell research.

Among his most influential contributions is the development of comprehensive transcriptional and epigenomic reference maps of pluripotent stem cells and the creation of the “ScoreCard” assay – an innovative tool that set new standards for assessing pluripotent cell quality and differentiation potential and is now widely adopted across the field. His subsequent studies have illuminated early regulatory dynamics during pluripotent cell specification and advanced understanding of chromatin remodeling and in vivo stem cell behavior using spatial transcriptomics and cutting-edge genomic technologies.

“Alexander Meissner’s work has fundamentally advanced our understanding of epigenetic regulation and cellular reprogramming,” said ISSCR President Hideyuki Okano. “Equally important is his dedication to mentorship and leadership, which has strengthened institutions and empowered the next generation of stem cell scientists.”

Since joining the Max Planck Society in 2017, Meissner has revitalized the Max Planck Institute for Molecular Genetics, recruiting outstanding junior investigators, strengthening institutional partnerships across Berlin, and fostering a collaborative and rigorous research culture.

He is also widely recognized as an exceptional mentor and teacher. Through intensive lab discussions, innovative communication exercises, and rigorous scientific training, he has prepared numerous trainees for leadership roles in academia and industry. His commitment to scientific excellence, integrity, and inclusivity is embedded in both his laboratory and institutional leadership.

The ISSCR also recognizes two outstanding scientists with Honorable Mention distinctions for the 2026 Momentum Award.

Kathrin Plath, University of California, Los Angeles, USA has made foundational contributions to our understanding of human pluripotency, cellular reprogramming, and X chromosome inactivation. Her work defining gene expression and chromatin dynamics during the conversion of somatic cells to pluripotency has provided critical mechanistic insight into how cell fate is established and stabilized. Her groundbreaking studies on epigenetic regulation of X chromosome inactivation have reshaped how the field considers sex differences in stem cell biology and differentiation. In addition to her scientific leadership, Dr. Plath has cultivated a collaborative and supportive research community at UCLA, mentoring trainees who have gone on to influential roles across academia and industry.

Joseph C. Wu, Stanford University School of Medicine, USA, is internationally recognized for advancing cardiovascular stem cell science from discovery to clinical translation. He has pioneered the use of patient-specific induced pluripotent stem cell–derived cardiomyocytes for disease modeling, pharmacogenomics-guided drug development, and regenerative medicine. His laboratory’s integrative genomics, proteomics, and metabolomics platforms have provided unprecedented insight into cardiac disease mechanisms and enabled precision approaches to therapy. Through rigorous preclinical research, his work has supported FDA IND approval and the launch of early-phase clinical trials involving human embryonic stem cell–derived cardiomyocytes, reflecting a sustained commitment to translational excellence.

“Professors Plath and Wu represent the extraordinary breadth and impact of stem cell science today,” Okano added. “Their innovation, rigor, and dedication to mentoring the next generation strengthen our global scientific community.”

Minimally invasive procedure effectively treats small kidney cancers

2026-03-03

OAK BROOK, Ill. – A large national study in Denmark following nearly 1,900 patients over almost a decade found that a minimally invasive procedure called ablation is as effective as surgery for treating small kidney cancers, with faster recovery and fewer complications. Results of the study were published today in Radiology, a journal of the Radiological Society of North America (RSNA). The research focused on patients with stage T1a renal cell carcinoma, a cancer that is increasingly found incidentally on CT scans performed for other reasons, such as imaging ...

SwRI earns CMMC Level 2 cybersecurity certification

2026-03-03

There is a clear correlation between health professionals’ use of alcohol and drugs and how they perceive that their substance use affects their work. The more they use, the worse they believe they are at taking care of their patients. Asked 3300 professionals about their substance use The research is based on data from almost 3300 doctors and nurses in Sweden, who reported having a problematic relationship with alcohol and illegal drugs. The participants were asked about their use of alcohol, cannabis and psychostimulants, ...

Life forms can planet hop on asteroid debris – and survive

2026-03-03

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets – including Earth – and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily withstands extreme pressure comparable to an ejection from Mars after an asteroid hit, as well as the inhospitable conditions it would face during the ensuing interplanetary journey. The study, published today in PNAS Nexus, suggests that microorganisms can survive remarkably more extreme conditions than expected, and raises questions about origins of life. The work ...

AI biases can influence people’s perception of history

2026-03-03

As members of the public increasingly turn to AI chatbots to understand their world, even subtle latent biases in the underlying models could affect public understanding of the present—and past. Daniel Karell and colleagues explored the effects of both unintentional and intentional political biases in LLMs by asking 1,912 research participants to read GPT-4o and Wikipedia summaries of two 20th century historical events: the 1919 Seattle General Strike and the 1968 Third World Liberation Front student ...

Prenatal opioid exposure and well-being through adolescence

2026-03-03

Children with prenatal opioid exposure face struggles in health, education, and social well-being throughout their childhoods and teenage years, even when sociodemographic factors are factored out. The global opioid crisis has largely been viewed as a crisis of adult users, but it has also led to a rise in children exposed to opioids before birth, only some of whom are diagnosed with neonatal abstinence syndrome—essentially, withdrawal. In 2023, approximately 95,000 American infants may have been exposed to opioids in utero. Gaëlle Simard-Duplain and Jonathan Zhang analyzed two decades of linked administrative data in British Columbia for 897,668 births ...

Big and small dogs both impact indoor air quality, just differently

2026-03-03

Dogs come in all shapes and sizes: from giant fluffy Newfoundlands to tiny short-haired Chihuahuas. And many furry companions like to spend their days inside near their humans. An initial study published in ACS’ Environmental Science & Technology reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did. “Pets are part of our indoor environment. By quantifying what dogs add to indoor air, we can build more realistic indoor air quality and ...
