Targeting p21‐Positive Senescent Chondrocytes via IL‐6R/JAK2 Inhibition to Alleviate Osteoarthritis

open access: yesAdvanced Science, Volume 12, Issue 11, March 20, 2025.
This study uncovers a novel mechanism behind uneven cartilage degeneration in knee osteoarthritis (OA). Elevated IL‐6R expression activates the IL‐6 pathway, leading to SIRT1 degradation, chondrocyte senescence, and reduced SOX9 activity, which impairs cartilage matrix synthesis. Notably, the JAK inhibitor tofacitinib prevents IL‐6R‐mediated senescence,

NF2 is Essential for Human Endoderm Development

open access: yesAdvanced Science, Volume 12, Issue 17, May 8, 2025.
This study demonstrates that NF2, moesin‐ezrin‐radixin like (MERLIN) tumor suppressor (NF2) is essential for human endoderm formation. NF2 knockout human induced pluripotent stem cells fail to form endoderm both in vitro and in vivo due to yes‐associated protein 1 (YAP1) nuclear translocation, redirecting differentiation toward myofibroblast‐like cells.

Immune and Angiogenic Profiling of Mesenchymal Stem Cell Functions in a Subcutaneous Microenvironment for Allogeneic Islet Transplantation

open access: yesAdvanced Science, EarlyView.
With emphasis on a diabetic state, this study highlights the role of mesenchymal stem cells (MSCs) in enhancing vascularization and modulating immune responses within a subcutaneous platform for cell transplantation for type 1 diabetes (T1D). Comprehensive profiling of MSC‐induced angiogenic and immune responses, provides insight into the role of MSCs ...
