Researchers develop low-cost scalable sensors to study genetic brain disorders

Researchers have demonstrated a new class of low-cost, scalable sensors that can be used to monitor electrical activity in human cerebral organoids. Because electrical signals are key to understanding brain function, this advance facilitates research into both neurodevelopment and genetic disorders such as Angelman syndrome. Human cerebral organoids are millimeter-sized tissues comprised of cell types … Read more

New neural organoid system improves scalability and reproducibility for research

Neural organoids have been heralded as having huge potential for advancing our knowledge of the brain in several fields. These include exploring the responses of brain tissue to drugs, investigating the effect of specific genetic mutations on neural electrical activity and characterising how neural systems develop.  In the past, viability of these systems has been limited by their scalability, reproducibility and longevity.  New research from King’s College London has succeeded in scaling up the organoid approach; … Read more

iXCells Biotechnologies joins international collaboration to evaluate chemotherapeutic toxicity in human organoids

iXCells Biotechnologies (“iXCells”), a leading provider of human cell-based solutions and custom iPSC services, today announced it has entered an international collaboration with Rosebud Biosciences (“Rosebud”), Kantify, and Incite to evaluate off-target chemotherapeutic toxicities in patient-specific organoids. Building on iXCells’ recent partnership with Rosebud and funded by Incite, the project will initially focus on predicting … Read more

Viagra ingredient improves symptoms in patients with Leigh syndrome

Sildenafil – an active ingredient also marketed under the name of Viagra – improves symptoms in patients with Leigh syndrome. This has now been reported in the Cell journal by researchers at Charité – Universitätsmedizin Berlin, together with teams from Heinrich Heine University Düsseldorf (HHU), University Hospital Düsseldorf (UKD), and the Fraunhofer Institute for Translational Medicine … Read more

Study aims to understand molecular origins of CTNNB1 neurodevelopmental syndrome

On the occasion of Rare Disease Day, the Biofisika Institute (CSIC, EHU) presents the progress of a project aimed at understanding the molecular origin of CTNNB1 neurodevelopmental syndrome, a rare disease caused by mutations in the beta-catenin protein. Although fewer than 50 cases of this pathology have been diagnosed in Spain, rare diseases affect a … Read more

Vitamin A and thyroid hormones in the retina shape fetal vision

Humans develop sharp vision during early fetal development thanks to an interplay between a vitamin A derivative and thyroid hormones in the retina, Johns Hopkins University scientists have found.  The findings could upend decades of conventional understanding of how the eye grows light-sensing cells and could inform new research into treatments for macular degeneration, glaucoma, and other age-related vision disorders.  Details of the study, which used … Read more

Researchers develop protocol to create functional acinar cells in organoids

Organoids are three-dimensional miniature models of organs, grown in a dish. They have become a valuable tool for studying human development, organ regeneration, function, and disease progression. Organoids derived from patient tissues or created through cell and genetic engineering allow researchers to investigate how specific proteins or their variants affect these processes. However, current approaches … Read more

Interferon response key to fighting rhinovirus infections in nasal passages

When a rhinovirus, the most frequent cause of the common cold, infects the lining of our nasal passages, our cells work together to fight the virus by triggering an arsenal of antiviral defenses. In a paper publishing January 19 in the Cell Press journal Cell Press Blue, researchers demonstrate how the cells in our noses … Read more

New marker identifies the functional maturity and heterogeneity of stem cell–derived islet organoids

Over 500 million people worldwide suffer from diabetes-a disease that contributes to major complications such as stroke, kidney failure, cancer, and Alzheimer’s disease. At the heart of this condition lies the dysfunction of pancreatic islets, the mini-organs called organoids responsible for regulating blood sugar, in both autoimmune type 1 diabetes and stress-induced type 2 diabetes. … Read more

New mouse model sheds light on smell loss and neural regeneration

A new study suggests that stem cells thought to be dormant may offer clues to why our sense of smell declines or is lost. Using a newly devised, three-dimensional model to study the regeneration of nerve tissue in the nose, researchers at Tufts University School of Medicine and the Graduate School of Biomedical Sciences (GSBS) and colleagues have discovered … Read more
