(Press-News.org) As a revolutionary 3D cell culture system, organoids bridge the gap between traditional 2D models and animal studies. This review synthesizes the current state of organoid engineering, from fundamental methods to transformative applications.
Organoid Construction
Key methods enable the generation of complex organoids:
Air-Liquid Interface (ALI) Culture: Ideal for modeling hollow organs and co-culturing with immune cells to study the tumor microenvironment.
Bioreactor Culture: Uses agitation to enhance nutrient exchange, supporting the growth of large, complex organoids like brains and enabling scalable production.
Vascularization: A critical advancement where organoids are integrated with blood vessels to improve survival and model neurovascular interactions.
Representative Models
The review details the construction of organoids for major organs, including kidneys, livers, lungs, brains, and intestines. These models are derived from pluripotent or adult stem cells using specific signaling pathways and scaffolds to recapitulate organ-specific structure and function.
Applications in Biomedicine
Organoids are transforming biomedical research:
Disease Modeling: They accurately mimic diseases like cancer, Zika virus infection, and cystic fibrosis.
Drug Screening & Biobanking: Patient-derived organoid biobanks allow for high-throughput drug testing and personalized treatment prediction.
Precision Medicine & Toxicity Assessment: They enable the selection of effective therapies for individual patients and provide human-relevant platforms for safety testing.
Application in TCM
Organoids offer a modern platform for TCM research, enabling the screening of active components, studying multi-target mechanisms, and evaluating the safety and efficacy of herbal compounds.
Frontier Technologies
The integration with cutting-edge technologies is pushing the field forward:
Gene Editing creates precise disease models.
Single-Cell RNA Sequencing reveals cellular heterogeneity.
3D Bioprinting allows for the precise fabrication of complex structures.
Artificial Intelligence analyzes complex organoid data for patterns and predictions.
Conclusion
Despite challenges in standardizing complexity and addressing costs, organoid technology is a powerful tool rapidly advancing our understanding of biology and disease. Its continued integration with other technologies promises to accelerate drug discovery and usher in a new era of personalized and integrative medicine.

In a Policy Forum, Dawson White and colleagues argue that international drug policy must distinguish between the coca leaf – a sacred plant long cultivated in South America – and its purified chemical derivative, cocaine. The World Health Organization’s Expert Committee on Drug Dependence (ECDD) is now reassessing the plant’s status, which, according to the authors, presents a rare opportunity to realign global drug policy with scientific evidence and Indigenous rights. Currently, the coca bush is classified under international law as a Schedule I drug, a group that also includes cocaine and heroin. While these drugs have a well-documented history of addiction and harm, ...
The Biodiversity Collections Network (BCoN), in collaboration with the American Institute of Biological Sciences (AIBS), has developed a comprehensive roadmap toward an integrated biological and environmental data network. The initiative, known as the Building an Integrated, Open, Findable, Accessible, Interoperable, and Reusable (BIOFAIR) Data Network project, addresses the urgent need to connect fragmented data held in biodiversity collections and other biological and environmental data repositories to tackle pressing societal challenges, including biodiversity loss, climate change, invasive ...
SAN ANTONIO — October 15, 2025 — Southwest Research Institute (SwRI) and 8 Rivers have patented a system that leverages fluctuations in energy demand by using liquid oxygen storage (LOX) to make power plants more cost-effective and efficient. To accomplish this, the Institute modified a recently developed power cycle, the Allam-Fetvedt Cycle, which combusts fuel, like natural gas, using an oxygen and carbon dioxide mixture to allow complete carbon capture, producing minimal greenhouse gas emissions.
The Allam-Fetvedt Cycle ...
For thousands of years, people in the Andes have chewed the leaves of the coca plant to stave off hunger, treat altitude sickness, and sustain energy. Yet under international law, this ancient crop is treated as harshly as cocaine and fentanyl. Now, scientists say it’s time to end that contradiction.
A new international perspective published in Science argues that scientific evidence clearly supports the coca leaf as a benign, useful, and culturally paramount crop plant that should be removed from the list of Schedule I substances – where it currently ...
When the experimental fusion system known as JT-60SA comes online in 2026, it will be the world’s largest fusion machine: a crowning achievement for Japan and Europe, which partnered to build it. Now, the research team has turned to the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) for critical measurement equipment.
The effort is part of a new agreement between PPPL, the National Institutes for Quantum Science and Technology (QST) of Japan and Europe’s Fusion for Energy (F4E), allowing for broader collaboration between the researchers.
“PPPL is among the first U.S. institutions to have its equipment installed ...
New York, NY (October 15, 2025) – The Icahn School of Medicine at Mount Sinai has received a prestigious $4.5 million, five-year K12 award from the National Institutes of Health (NIH) to establish a pioneering program that will train the next generation of leaders in women’s health research.
The program, called the Mount Sinai Life-course Exposomics Analytic Program (LEAP) in Women’s Health, is led by Rosalind J. Wright, MD, MPH, Dean for Public Health and Chair of the Department of Public Health at the Icahn School of Medicine. LEAP is part ...
WASHINGTON—People with excess body fat who build and keep muscle may be less likely to develop obesity-induced heart, liver, or kidney damage or die early, according to a new study published in The Journal of Clinical Endocrinology & Metabolism.
Despite clear evidence that excess body fat can directly cause illness, obesity is often viewed as a risk factor for heart disease and diabetes rather than a chronic disease.
Obesity is defined as a body mass index (BMI) of 30 or higher. BMI is ...
Lung cancer screening might be the best-kept secret in health care today. Only about 16 percent of those who are eligible in the U.S. get screened for lung cancer, but a study coming out in NEJM Catalyst on Wednesday provides a roadmap for how health systems can improve those numbers. The study details how the UR Medicine primary care network reached a nearly 72 percent lung cancer screening rate.
“Our biggest success was not only screening a high percentage of eligible patients, but also enrolling those patients in the comprehensive program to ensure they receive the necessary annual follow-up screenings,” said Robert Fortuna, MD, ...
Have you ever wondered what makes shark skin so tough and sleek? It’s dermal denticles – tiny, tooth-like structures that cover a shark’s skin. Made of the same material as teeth and shaped like small scales with grooves, these microscopic armor plates aren’t just for show. Dermal denticles serve important roles in helping sharks glide effortlessly, and protect their skin, especially during mating.
Although much is known, researchers still lack a full understanding of how dermal denticle shape changes across different parts of the shark’s body as it grows and if there are differences between ...
New York, NY [October 15, 2025]—Doctors often must make critical decisions in minutes, relying on incomplete information. While electronic health records contain vast amounts of patient data, much of it remains difficult to interpret quickly—especially for patients with rare diseases or unusual symptoms.
Now, researchers at the Icahn School of Medicine at Mount Sinai and collaborators have developed an artificial intelligence system, called InfEHR, that links unconnected medical events over time, creating a diagnostic web that reveals hidden patterns. Published in the September 26 online issue of Nature Communications, the study shows that Inference on Electronic Health ...
