Bioinspired, Mitochondria‐Targeted Single‐Atom Nanozyme Enhances Bone Regeneration by Reprogramming Stem Cell Energy Metabolism​

Advanced Materials, EarlyView.
A bioinspired nanozyme—triphenylphosphonium (TPP)‐dendritic mesoporous silica nanoparticle (DMSN)‐Fe/Cu—mimics mitochondrial complex IV and targets mitochondria to regulate cellular energy metabolism. This approach markedly boosts bone regeneration in vivo, as demonstrated by enhanced bone volume and mineral density in critical‐sized bone defects rat ...

Perfusion Bioreactor Culture Incorporating Mechanical Confinement Enhances Mesenchymal Stem Cell Extracellular Vesicle Production and Wound Healing Potential

Advanced Materials Technologies, EarlyView.
Scalable manufacturing challenges and limited potency remain two of the most intransigent issues limiting clinical translation of EV therapeutics. Mechanical cues can induce phenotypic changes and increased vesiculation in EV source cells without the use of extraneous reagents, chemicals, and/or cargo, thereby potentially drastically improving the ...

Long non-coding RNA-2271 promotes osteogenic differentiation in human bone marrow stem cells

Open Life Sciences, 2018
Human bone marrow mesenchymal stem cells (BMSCs) are of great significance for bone regeneration and bone formation. Long non-coding RNAs (lncRNAs) may be involved in modulating cell differentiation.

Shaping Carbon Nitrides for Advanced Macrostructures

Advanced Materials Technologies, EarlyView.
This review examines how carbon nitride can be shaped through a range of printing and interfacial assembly methods. By bringing together additive manufacturing and liquid–liquid structuring concepts, carbon nitride is moving beyond its traditional powder‐based photocatalyst form toward digitally designed robust macroscale architectures with high design

New perspectives in human stem cell therapeutic research

BMC Medicine, 2009
Human stem cells are in evaluation in clinical stem cell trials, primarily as autologous bone marrow studies, autologous and allogenic mesenchymal stem cell trials, and some allogenic neural stem cell transplantation projects.

Spatiotemporal Sequential Delivery of Chidamide Regulates Macrophage Reprogramming in Lymphoma Microenvironment Through HDACs‐STAT3 Pathway

Advanced Science, EarlyView.
Our study identifies the HDACs‐STAT3 axis as key regulator for M2 macrophage accumulation in DLBCL. We developed Chid@M2pep‐EVs/TP, a pH‐responsive drug delivery system for M2 macrophage specific chidamide administration. By coupling M2‐targeted chidamide with EVs‐mediated delivery, this system reprograms M2 to M1 via HDAC inhibition and STAT3 ...

Cellular Snowballing: Cell Adhesion and Migration Drive the Self‐Assembly of Cell‐Microgel Biohybrid Spheroids

Advanced Science, EarlyView.
A new class of biohybrid spheroids is engineered through the self‐assembly of adherent cells and extracellular matrix‐mimetic hydrogel microparticles (microgels). By mimicking a snowballing effect, this approach enables scalable formation of porous, millimeter‐scale spheroids with enhanced cell viability and molecular diffusion.

Dnmt3b ablation impairs fracture repair through upregulation of Notch pathway [PDF]

, 2020
We previously established that DNA methyltransferase 3b (Dnmt3b) is the sole Dnmt responsive to fracture repair and that Dnmt3b expression is induced in progenitor cells during fracture repair.
