Summary: The process of developing a new drug is time-consuming and expensive, and hepatotoxicity is a major concern. Animal models have limitations due to interspecies differences, but human induced pluripotent stem cells (hiPSCs) offer new possibilities for drug testing. We miniaturized the process of generating hepatic organoids using hiPSC-derived mesenchymal stem cells, hepatocytes, and endothelial cells. These organoids were cultivated in vitro using static and dynamic cultures, and could be maintained for up to 1 week. This hiPSC-derived liver organoid model could potentially replace animal testing in pharmacological and toxicological studies.

Summary: During space travel, astronauts face the challenge of adapting to microgravity and stressful living conditions. The impact of microgravity on organ development is not well understood, and this study used mouse mammary epithelial cells to investigate its effects. The results suggest that microgravity can cause abnormal changes in mammary epithelial cells and increase the risk of cancer.

Summary: The study demonstrates that loss of PDPN in murine cSCC cells leads to decreased migration and invasion in vitro, highlighting the crucial role of PDPN in cSCC progression. Experiments with Pdpn mutants further reveal the importance of both intra- and extracellular domains in cancer cell invasion. Orthotopic injection of labeled cells into nude mice confirms the impact of PDPN on tumor infiltration into the stroma.

Summary: Pancreatic ductal adenocarcinoma (PDAC) has the highest mortality rate among major cancers, and current therapies have had limited success. Understanding the complex tumor microenvironment (TME) of PDAC, including fibrotic matrix and immunosuppressive features, is crucial for developing effective treatments. Organotypic tumor slices from patient tumors provide a valuable model system to study TME interactions and potential therapeutic approaches for personalized cancer therapy.

Summary: In vitro preparations offer valuable tools for studying and modeling seizures and epilepsy, as well as screening anti-seizure compounds. However, these models are simplifications of reality and have limitations. Therefore, a combination of in vitro models, in vivo studies, chronic epilepsy animal models, and human cell/tissue-derived preparations is recommended to maximize their potential value.

Summary: This study showed that organotypic culture of testicular tissue from infants with cryptorchidism could support the development of spermatogonia and somatic cells, with the addition of retinoic acid (RA) inducing spermatocytes and enhancing the maturation of Sertoli cells. The absence of RA in the culture medium led to an increase in peritubular myoid cells. This research provides insights for future studies on in vitro spermatogenesis.

Summary: This study presents a method for generating human epidermis organotypic cultures (HEOCs) from primary keratinocytes and an immortalized keratinocyte cell line (KerTr). The HEOCs were characterized and shown to express markers associated with proliferation and differentiation. The ability to generate HEOCs reproducibly on a large scale makes them a valuable model for drug screening and studying epidermal pathologies.

Summary: Insect odorant receptors have been suggested to function as ligand-gated cation channels with OrX/Orco heteromers. Different G proteins mediate the metabotropic activity of these receptors, providing insight into their natural and artificial tuning features for potential applications in chemogenetics, drug screening, and repellent design.

Summary: Adaptation is important in sensory systems, and the vomeronasal system controls social behaviors by detecting pheromones. This study found that vomeronasal neurons exhibit short-term spike frequency adaptation to repeated stimuli, and slow inactivation of Na+ channels contributes to this adaptation.

Summary: Seizures are a common symptom in gliomas, and the pathogenesis of tumor-related seizures may involve the peritumoral microenvironment. This study investigates the role of exosomes released by glioma cells in regulating neuronal synchrony. The results demonstrate that exosomes can induce synchronization in early-stage neuronal cultures but disrupt synchrony in mature cultures. The mechanisms involve the formation of new neuronal branches, modifications in synaptic efficiency, and direct effects on neuronal electrical properties. Additionally, exosomes selectively enhance glutamatergic signaling in mature cultures and contribute to the neurological pathologies of patients with low-grade glioma.

Summary: The aim of this study was to evaluate the prevalence of smell and taste dysfunction 2 years after mildly symptomatic SARS-CoV-2 infection, taking into account the background of chemosensory dysfunction in the non-COVID-19 population. The results showed that cases of SARS-CoV-2 infection still exhibited a significant excess of olfactory dysfunction 2 years after the infection when compared to matched controls.

Summary: The COVID-19 pandemic highlighted our limited understanding of human olfactory physiology. By using acute slices of human olfactory epithelium and whole-cell patch-clamp technique, this study characterized the electrical properties of olfactory sensory neurons and supporting cells. The study also demonstrated the intact transduction cascade in this preparation through responses to odorant mixtures. This research provides valuable insights into human olfactory physiology and lays the foundation for future studies.

Summary: The Ca2+-activated Cl over bar channel TMEM16B plays a crucial role in olfactory sensory neurons by controlling the transduction current and the length of action potentials. Knockout of TMEM16B in mice resulted in larger EOG responses, faster kinetics, and altered adaptation to repeated stimulation. This paradoxical effect may be due to the removal of clamping and/or shunting action of Ca2+-activated Cl over bar currents.

Summary: Neural interfaces have the potential to monitor and stimulate the brain for the treatment of nervous disorders. This study shows that uncoated Ti3C2Tx MXene material can be used as a neural interface without altering the physiological properties of neuronal tissue. It preserves the basal physiology of neuronal activity and has promising potential for neural prosthetic devices and neuroscience research.
