Organoid fusions as models to study meninges-brain signaling

Organoid fusions as models to study meninges-brain signaling
2025-03-25
(Press-News.org) A new study in the peer-reviewed journal Stem Cells and Development describes the development of a co-culture system of neural organoids generated from human induced pluripotent stem cells (iPSCs) fused with fetal leptomeninges from mice with fluorescently labeled meninges, called leptomeningeal neural organoid (LMNO) fusions.

Vivian Gama, PhD, from Vanderbilt University, Julie Siegenthaler, PhD, from University of Colorado Anschutz Medical Campus, and coauthors, present a proof-of-concept study that tests the stability of the different cell types in the leptomeninges (fibroblasts and macrophages) and the fused neural organoid (progenitors and neurons), as well as the interface between the organoid and meningeal tissue.

“We test the longevity of the fusion pieces after 30 days and 60 days in culture, describe best practices for preparing the meninges sample before fusion, and examine the feasibility of single or multiple meninges pieces fused to a single organoid,” stated the investigators.   

“This groundbreaking model advances the tissue organoid field by recognizing and correcting for the absence of the necessary supporting matrix to a 3D structure, in this case, the meninges” states Graham C. Parker, PhD, Editor-in-Chief of Stem Cells and Development and the Department of Pediatrics, Wayne State University School of Medicine, Detroit, MI.

A multimodal light manipulator

A multimodal light manipulator
2025-03-25
Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas sensing and optical computing. Now, applied physicists at the Harvard  John A. Paulson School of Engineering and Applied Sciences (SEAS) have invented a new type of interferometer that allows precise control of light’s frequency, intensity and mode in one compact package.   Called a cascaded-mode interferometer, it is a single waveguide on a silicon-on-insulator ...

OU researcher leverages technology for alcohol disorder interventions in primary care
2025-03-25
OKLAHOMA CITY – According to the Centers for Disease Control and Prevention, 1 in 7 adults in the United States will experience a substance use disorder during their lifetime. University of Oklahoma College of Medicine faculty member Brandi Fink, Ph.D., is working with primary care clinics and health care systems to identify people with an alcohol use disorder and intervene early before the problem worsens. Fink, an associate professor in the Department of Psychiatry and Behavioral Sciences, created an assessment for patients to fill out on an iPad while waiting for an appointment ...

Automated lead nurturing boosts sales—but only under the right conditions

2025-03-25
Businesses invest billions in marketing automation, and many assume that Automated Lead Nurturing (ALN) is a proven driver of sales. However, a new Journal of Marketing study reveals that ALN is not a one-size-fits-all solution. The research finds that while ALN improves engagement and enhances salesperson–lead interactions, its impact on sales conversions varies significantly across industries and customer segments. Authored by Johannes Habel (University of Houston), Nathaniel Hartmann (University of South Florida), Phillip Wiseman (Texas Tech University), Michael Ahearne (University of ...

Lessons from Venezuela’s democratic collapse: How opposition movements can defy autocratic leaders

Lessons from Venezuela’s democratic collapse: How opposition movements can defy autocratic leaders
2025-03-25
Until the 1990s, Venezuela was home to one of the most established democracies in Latin America. Today, however, it stands as one of the region’s most firmly entrenched authoritarian regimes. How did this shift occur, and what can other countries learn from Venezuela’s transformation? A new paper from political scientist Laura Gamboa at the University of Notre Dame chronicles the country’s 25-year evolution, during which Hugo Chávez and his successor, Nicolás Maduro, destroyed ...

USU ecologists document Utah's bee species and say beehive state is rich in bee diversity

USU ecologists document Utahs bee species and say beehive state is rich in bee diversity
2025-03-25
TOOELE, UTAH, USA -- Wildlife conservation is critical to sustaining the planet’s biodiversity and health. But putting together a conservation plan is a tall order. First of all, you need to determine what species you’re conserving, along with their numbers, habitat needs, threats and how they fit into a complex ecosystem. As pollinators for native plants and food crops, bees play a pivotal role in our ecosystem, according to Utah State University ecologist Joseph Wilson. He and undergraduate researcher Anthony Hunsaker took on the herculean task of documenting Utah’s bee species using online occurrence records from the Symbiota Collection of Arthropods ...

A hit of dopamine tells baby birds when their song practice is paying off

2025-03-25
DURHAM, N.C. -- In his home office in Durham, Duke neuroscientist Richard Mooney shows a series of images of a bird’s brain on song. In one, what looks like a pointillist painting illustrates a young zebra finch’s myriad attempts to sound more like an adult, capable of wooing a mate. In another, squiggly lines trace the ebb and flow of chemical signals in the reward circuit of the bird’s brain. “Their songs don’t sound like much at first,” said Mooney, who has studied birdsong for four decades. That’s because some things take considerable practice to master. Nobody walks onto a tennis court for the first time and plays ...

Basketball analytics investment is key to NBA wins and other successes

Basketball analytics investment is key to NBA wins and other successes
2025-03-25
If you filled out a March Madness bracket this month, you probably faced the same question with each college match-up: What gives one team an edge over another? Is it a team’s record through the regular season? Or the chemistry among its players? Maybe it’s the experience of its coaching staff or the buzz around a top scorer.  All of these factors play some role in a team’s chance to advance. But according to a new study by MIT researchers, there’s one member who consistently ...

Scientific cooperation is strategic for Brazil to strengthen relations with Europe

Scientific cooperation is strategic for Brazil to strengthen relations with Europe
2025-03-25
Relations between Europe and South America – and especially with Brazil - are at a favorable moment, due to factors such as the free trade agreement between Mercosur and the European Union, signed in December 2024 and currently being approved. However, in order to take advantage of this window of opportunity and be competitive, Brazil must continue to expand scientific and technological cooperation with European partners.   This assessment was made by the Brazilian Ambassador to Germany, Roberto Jaguaribe, ...

Engineering antibodies with a novel fusion protein

Engineering antibodies with a novel fusion protein
2025-03-25
The Food and Drug Administration has approved more than 100 monoclonal antibodies to treat a range of diseases. Other antibodies are used by physicians to diagnose conditions or by scientists to advance research projects. Even with significant expansion in the global market for antibodies used in clinical care and research, scientists recognize that there is still untapped potential for finding new antibodies. Many proteins group together in what are called protein complexes to carry out biological functions. The traditional method of generating antibodies by immunizing animals struggles to make antibodies related to these protein complexes. The conventional ...
