In modern dentistry, prosthetic approaches such as implants and dentures have been developed as symptomatic solutions for tooth loss. However, the complete regeneration of teeth and periodontal tissue, an ultimate aspiration of humanity, remains unachieved. Recent advancements in fundamental scientific technologies, including single-cell RNA sequencing and spatial transcriptomics, have significantly advanced our molecular understanding of tooth development, paving the way toward achieving this goal.

Cyclin-dependent kinases (CDKs) 4 and 6 (CDK4/6) are important regulators of the cell cycle. Selective CDK4/6 small-molecule inhibitors have shown clinical activity in hormonal receptor-positive (HR) metastatic breast cancer, but their effectiveness remains limited in other cancer types. CDK4/6 degradation and improved selectivity across CDK paralogs are approaches that could expand the effectiveness of CDK4/6 targeting.

Cardiovascular and cardiometabolic diseases are leading causes of morbidity and mortality worldwide, driven in part by chronic inflammation. Emerging research suggests that the bone marrow microenvironment, or marrow niche, plays a critical role in both immune system regulation and disease progression. The bone marrow niche is essential for maintaining hematopoietic stem cells (HSCs) and orchestrating hematopoiesis.

The safety of a 2'--methoxyethyl antisense oligonucleotide (ASO) was investigated in Mauritius cynomolgus monkeys in a 41-week Good Laboratory Practice (GLP) toxicity study after multiple intrathecal (IT) administrations. Histopathological examination revealed ectopic formation of lymphoid follicles in the spinal cord (SC) at the injection site at all doses and the presence of granular material in neurons of the SC in high-dose animals. The granular material was seen in all the segments of the SC, but mainly in the lumbar segment and persisted at the end of the 26-week recovery period, while the lymphoid follicles showed a reversibility trend.

Introduction: Bone marrow-derived mesenchymal stem cell-derived extracellular vesicles (BMSC-EVs) are widely used for therapeutic purposes in preclinical studies. However, their utility in treating diabetes-associated atherosclerosis remains largely unexplored. Here, we aimed to characterize BMSC-EV-mediated regulation of autophagy and macrophage polarization.
