Summary: Degenerative bone disorders such as IVDD, OA, and OP present significant challenges for aging populations with no effective treatments available. The use of stem cell-derived EVs as a novel therapeutic approach holds promise in addressing these disorders. However, a comprehensive assessment of EV-based therapies in degenerative bone disorders is currently lacking. This review aims to fill this gap by summarizing the current state of the field and discussing the potential of EV-based treatments for IVDD, OA, and OP.

Summary: Advances in biomaterial science have improved our understanding of how material cues impact stem cell function. These approaches provide more realistic models of the cell niche and have led to novel mechanobiological studies in model organisms. This review discusses the importance of material cues within the cell niche, highlights key mechanotransduction pathways, and presents recent evidence of material cues regulating tissue function in vivo.

Summary: The study reveals that telomere attrition leads hematopoietic stem cells towards differentiation into megakaryocytic lineage through upregulated innate immune signaling response, ultimately compromising their self-renewal capabilities and leading to depletion. Targeting the IFI16 signaling axis could potentially prevent functional decline of hematopoietic stem cells under conditions affecting telomere maintenance.

Summary: Multiple myeloma is a malignant disease characterized by bone marrow tumors and bone lesions. Autologous stem cell transplantation followed by lenalidomide maintenance therapy is the standard treatment for multiple myeloma. However, relapse is common. In this study, the addition of a checkpoint inhibitor to lenalidomide maintenance therapy was investigated and found to enhance the immune response and improve the efficacy of the treatment in a mouse model of multiple myeloma.

Summary: Intermediate filaments have emerged as important regulators of cellular signaling events, beyond providing structural support, by regulating cell differentiation and influencing cell fate decisions in conjunction with stem cell signaling pathways. Lack of IFs causes perturbed stem cell differentiation, and deregulation in these signaling pathways can result in various diseases. Studying the interaction and regulation of IFs with cell signaling helps expand our understanding of IF-linked diseases.

Summary: Stem cells have shown great potential for tissue regeneration and repair due to their unlimited self-renewal and differentiation capabilities. However, the complex interactions between niches and stem cells, along with the limitations of current systems or methods, pose challenges to the multi-faceted applications of stem cells. Emerging evidence suggests that synchrotron infrared microspectroscopy may offer a promising non-invasive technology for stem cell research.

Summary: In this study, a core/shell-structured two-dimensional silicene nanosheets coated with mesoporous silica layer were utilized as a drug delivery system for localized anesthesia. The system exhibited on-demand and long-lasting regional anesthesia effect, surpassing the analgesic effect of free drugs. It also demonstrated the ability to improve pain threshold and reduce neuronal activation in relevant pathways.

Summary: Adsorption kinetic studies were conducted using chiral mesoporous materials NGM-1 and NFM-1 for the enantiomeric separation of l- and d-valine, with calcined versions fitting the Langmuir model and exhibiting high sorption capacities. The results and analysis indicate strong adsorbate-adsorbent interaction and the formation of a monolayer of amino acids on the internal mesopore surface for the preferred enantiomers.

Summary: Conflicting evidence exists on the clinical efficacy of exogenous melatonin for the treatment of sleep disorders, possibly due to differences in melatonin formulations and doses affecting its pharmacokinetics. Future studies should investigate how different pharmacokinetic parameters of melatonin formulations affect the treatment efficacy of sleep and circadian disorders more systematically.

Summary: In this study, melatonin was encapsulated in mesoporous silica with the addition of a coating of cellulose acetate phthalate. The release kinetics of melatonin and its metabolism were investigated in simulated gastrointestinal fluids and in an in vitro model of the intestinal tract. The presence of the coating affected the release and absorption of melatonin, as well as its catabolism. The confinement of melatonin in the mesopores had a slight impact on its permeability and metabolism.

Summary: Chorioamnionitis is a risk factor for preterm birth and can lead to neurodevelopmental delay and cognitive disorders. This study used pigs as a model to investigate the effects of prenatal lipopolysaccharide (LPS) exposure on the proteome in cerebrospinal fluid (CSF) and brain tissue at birth and postnatally. The results showed changes in CSF protein levels at birth, but most of these changes resolved a few days later. The hippocampus exhibited high neuronal plasticity in response to perinatal inflammation. The findings suggest that CSF protein expression at birth may predict later structural brain damage in preterm infants exposed to various types and durations of chorioamnionitis-related inflammation in utero.

Summary: The characterization of the protein corona is crucial for understanding the biological properties of nanomaterials, especially in the case of mesoporous silica particles used as drug delivery excipients. The shape and aspect ratio of the particles have a significant impact on the composition and coverage of the protein corona, which in turn affects the biological properties of the particles.

Summary: SBA-15 mesoporous silica (MPS) is widely used in oral drug delivery, but its application in solidifying lipid-based formulations is still underexplored. This study investigates the impact of MPS microporosity on the solubility and oral pharmacokinetics of the prostate cancer drug abiraterone acetate (AbA) and finds that microporosity plays a key role in enhancing AbA solubilization.

Summary: The integrity of the blood-brain barrier (BBB) is crucial for the health of the nervous system. In this study, we found that loading the compound probucol within mesoporous silica particles (MSP) can enhance its antioxidant effects, thereby protecting the function and integrity of brain endothelial cells. Through in vitro and in vivo experiments using zebrafish models, we demonstrated that probucol-loaded MSPs can significantly reduce cellular damage caused by oxidative stress and inflammation, and decrease the permeability of the BBB.

Summary: Preterm infants are at increased risk of impaired neurodevelopment, which may be related to reduced levels of insulin-like growth factor 1 (IGF-1) after birth. This study used preterm pigs as a model to investigate the effects of postnatal IGF-1 supplementation on brain development. The results showed that IGF-1 treatment improved motor function and enhanced GABAergic maturation in the caudate nucleus, but reduced myelination in certain brain regions. These findings suggest that supplemental IGF-1 may support postnatal brain development in preterm infants.
