Credit: Zipeng Zeng/Li Lab The organoids, which resemble a kidney’s uretic buds, provide a way to study kidney disease that could lead to new treatments and regenerative approaches for patients. A team of scientists at the Keck School of Medicine of USC has created what could be a key building block for assembling a synthetic kidney. In a new study in Nature Communications, Zhongwei Li and his colleagues describe how they can generate rudimentary kidney structures, known as organoids, that resemble the collecting duct system that helps maintain the body’s fluid and pH balance by concentrating and transporting urine. “Our progress in creating new types of kidney organoids provides powerful tools for not only understanding development and disease, but also finding new treatments and regenerative approaches for patients,” said Li, the study’s corresponding author and an assistant professor of medicine, and of stem cell biology and regenerative medicine.

Credit: Richard Carrasco Creating the building blocks The first authors of the study, PhD student Zipeng Zeng and postdoc Biao Huang, and the team started with a population of what are known as ureteric bud progenitor cells, or UPCs, that play an important role in early kidney development. Using first mouse and then human UPCs, the scientists were able to develop cocktails of molecules that encourage the cells to form organoids resembling uretic buds — the branching tubes that eventually give rise to the collecting duct system. The scientists also succeeded in finding a different cocktail to induce human stem cells to develop into ureteric bud organoids. An additional molecular cocktail pushed ureteric bud organoids — grown from either mouse UPCs or human stem cells — to reliably develop into even more mature and complex collecting duct organoids. The human and mouse ureteric bud organoids can also be genetically engineered to harbor mutations that cause disease in patients, providing better models for understanding kidney problems, as well as for screening potential therapeutic drugs. As one example, the scientists knocked out a gene to create an organoid model of congenital anomalies of the kidney and urinary tract, known as CAKUT. In addition to serving as models of disease, ureteric bud organoids could also prove to be an essential ingredient in the recipe for a synthetic kidney. To explore this possibility, the scientists combined mouse ureteric bud organoids with a second population of mouse cells: the progenitor cells that form nephrons, which are the filtering units of the kidney. After inserting the tip of a lab-grown ureteric bud into a clump of NPCs, the team observed the growth of an extensive network of branching tubes reminiscent of a collecting duct system, fused with rudimentary nephrons. “Our engineered mouse kidney established a connection between nephron and collecting duct — an essential milestone towards building a functional organ in the future,” said Li.

Credit: Karl Barber, Schmidt Science Fellows Scientists have repurposed the genetic modification technology CRISPR to identify antibodies in patient blood samples in a move that could inspire a new class of medical diagnostics in addition to a host of other applications. The technology involves customizable collections of proteins which are attached to a variant of Cas9, the protein at the heart of CRISPR, that will bind to DNA but not cut it as it would when used for genetic modification. When these Cas9-fused proteins are applied to a microchip sporting thousands of unique DNA molecules, each protein within the mixture will self-assemble to the position on the chip containing its corresponding DNA sequence. The researchers have called this technique ‘PICASSO’, short for peptide immobilization by Cas9-mediated self-organization. By then applying a blood sample to the PICASSO microarray, the proteins on the microchip that are recognized by patient antibodies can be identified. The team led by Dr. Stephen Elledge at Harvard Medical School and Brigham and Women’s Hospital, Boston, has published the research online in Molecular Cell today (August 13, 2021). The paper’s first author, Dr. Karl Barber, is a 2018 Schmidt Science Fellow, with much of the work to develop the technology taking place during his Fellowship Research Placement in corresponding author Dr. Elledge’s laboratory. Describing PICASSO, Dr. Barber said: “Imagine you want to paint a picture on a canvas, but instead of painting in a normal fashion, you mix all of your paints together, splash it on the canvas, and the perfect picture emerges. With our new technique, you place DNA molecules at defined locations on a surface and each protein from a mixture will then self-assemble to its corresponding DNA sequence, like an automated paint-by-number kit. The resulting DNA-templated protein microarrays allow you to quickly identify antibodies in clinical samples that recognize whatever proteins you are interested in.” The research team has demonstrated that the technology works to assemble thousands of different proteins, suggesting that it could be readily adapted as a broad-spectrum medical diagnostic tool. In the paper, they used the technique to detect antibodies binding to proteins derived from pathogens, including SARS-CoV-2, from the blood of recovering COVID-19 patients. Dr. Barber said: “In this work, we demonstrated the application of PICASSO for protein studies, creating a tool that we believe could be quickly adapted for medical diagnostics. Our protein self-assembly technique could also be harnessed for the development of new biomaterials and biosensors just by attaching DNA targets to a scaffold and allowing Cas9-linked proteins to bind.” Group Leader, Dr. Elledge, commented: “One of the most exciting aspects of this work is the demonstration of how CRISPR can be applied in an entirely new setting. Previously, CRISPR has been used primarily for gene editing and the detection of DNA or RNA. PICASSO brings the power of CRISPR into a new realm of protein studies, and the molecular self-assembly strategy we show may assist in developing new research and diagnostic tools.” Dr. Megan Kenna, Executive Director of Schmidt Science Fellows, said: “This technology has the potential to be used as a medical diagnostic tool that could, one day, provide doctors with a way to quickly determine the diagnosis and best course of treatment for each individual patient.”  “The way that Karl and the research team have brought together fundamental biology with molecular engineering to make this important discovery shows why the interdisciplinarity at the heart of our Fellowship is so critical to advancing science.” The research was supported by Schmidt Science Fellows, the Jane Coffin Childs Memorial Fund for Medical Research, National Science Foundation, and the Howard Hughes Medical Institute.

The fish moves away in response to a sound played underwater, showing that it can tell which direction the sound comes from. Credit: Antonia Groneberg, Charité and Jonathan Anand Researchers at Charité have solved the puzzle of directional hearing underwater. When underwater, humans cannot determine where a sound comes from. Sound travels about five times faster there than on land. That makes directional hearing, or sound localization, nearly impossible because the human brain determines the origin of a sound by analyzing the time difference between its arrival at one ear versus the other. By contrast, behavioral studies have shown that fish can locate sound sources such as prey or predators. But how do they do it? Neuroscientists from Charité – Universitätsmedizin Berlin have solved the puzzle, describing the auditory mechanism of a tiny fish in the journal Nature. It has quite a grand name for such a tiny creature: Danionella cerebrum, a fish measuring about 12 millimeters, nearly entirely transparent for its whole lifetime, native to streams in southern Myanmar. Danionella has the smallest known vertebrate brain, but it still displays a number of complex behaviors, including communicating by sound. That, and the fact that scientists can see directly into its brain – the head and body are nearly transparent – make it interesting for brain research. Prof. Benjamin Judkewitz, a neurobiologist with the NeuroCure Cluster of Excellence at Charité, and his team are using the tiny fish as a window into fundamental questions such as how nerve cells communicate with each other. Their most recent work is dedicated to the development of the sense of hearing and the decades-old question of how fish can locate a source of sound underwater. Previous textbook models of directional hearing fall short when applied to underwater environments. The acoustic world, above and under the water From whale song to the chirping of birds or a predator stalking its prey, when sound is emitted from a source, it spreads to the medium around it as motion and pressure oscillations. This can even be felt by placing a hand on the cone of a speaker. There is the vibration of particles, the adjacent air is moved – this is known as particle velocity. The particle density also changes as the air is compressed. This can be measured as sound pressure. Terrestrial vertebrates, including humans, perceive the direction of sound primarily by comparing the volume and time when sound pressure reaches the two ears. A noise sounds louder and arrives sooner in the ear closer to the source of the sound. That strategy does not work underwater. Sound spreads much faster there, and it is not muffled by the skull. That means that fish should also be incapable of directional hearing, as there is practically no difference in volume and arrival time between their ears. And yet, spatial hearing has been observed in behavioral studies of various species. “To find out whether, and above all how, a fish can tell the direction of sound, we built special underwater speakers and played short, loud sounds,” explains Johannes Veith, one of the two first authors of the current study. “Then we analyzed how often Danionella avoids the speaker, meaning that it recognizes the direction the sound is coming from.” For the analyses, a camera was used to film every fish from above and track its exact position. This live tracking method brought a crucial advantage: the team was now able to zero in on echoes and suppress them. Fish hear completely differently What humans perceive through the eardrum is sound pressure, not particle velocity. Fish have a completely different hearing mechanism: They can perceive particle velocity, too. How exactly this works in Danionella was revealed by images taken with a purpose-built laser scanning microscope that scans the structures inside the fish ear in a strobe pattern while a sound is played. Close to an underwater speaker, water particles move back and forth along an axis oriented toward and away from the speaker. The particle velocity moves along the direction in which the sound spreads. A fish close to the speaker also moves with the water, but tiny stones in the inner ear known as otoliths are slower to move due to inertia. This results in a tiny motion detected by sensory cells in the ear. The problem is that this means the fish can only detect the axis along which the sound moves – but not the direction from which it comes. This is because sound is a form of oscillation, a continuous back-and-forth movement. This problem is solved by analyzing particle velocity depending on the current sound pressure – one of the various hypotheses that sought to explain the mechanism involved in directional hearing in the past. It turned out to be the only theory that fit the researchers’ results: “Sound pressure sets the compressible swim bladder in motion, which in turn is recognized by hair cells in the inner ear. Through this second, indirect hearing channel, sound pressure gives fish the reference they need for directional hearing. That’s exactly what one model of spatial hearing from the 1970s predicted – and now we’ve confirmed it experimentally,” Judkewitz says. The team was also able to show that directional hearing can be fooled by reversing the acoustic pressure. When that was done, the fish swam in the opposite direction, meaning toward the source of sound. Micro-CT images of the hearing apparatus in Danionella show that it is similar to the sensory organ of about two-thirds of living freshwater fish, or about 15 percent of all vertebrate species. This suggests that the directional hearing strategy that the team has now confirmed, involving combined analysis of sound pressure and particle velocity, could be widespread. The researchers plan to continue their work to determine which nerve cells specifically are activated when sounds are played underwater.
