3D‐Printed Piezoionic/Bioelectronic Hydrogel for Electro‐Metabolic Regulation of Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
A 3D‐printed piezoionic GPMx hydrogel enables stable electromechanical signal generation under mechanical loading, exhibiting long‐term durability and low fatigue. As a bioactive patch, it restores endogenous bioelectricity to stimulate osteogenesis via Ca2+ influx and mitochondrial activation, while simultaneously enabling label‐free alkaline ...

Tracking Spatiotemporal Extracellular Matrix Evolution and Tissue Fusion in 3D Microtissues via Click Chemistry‐Based Metabolic Labelling

Advanced Healthcare Materials, EarlyView.
Metabolic labeling of nascent proteins in 3D microtissue spheroids provides a powerful analytical approach for large‐scale tissue engineering. Incorporation of non‐canonical amino acids with fluorescent tagging enables spatiotemporal investigation of extracellular matrix deposition and its evolution during multicellular tissue development and fusion ...

Investigation of the effect of low oxygen tension on the osteogenic differentiation of human mesenchymal stem cells [PDF]

, 2010
Osteogenic differentiation of hMSC into osteoblasts is a prerequisite for subsequent bone formation. Numerous studies have explored osteogenic differentiation under standard tissue culture conditions, which usually employ 21% of oxygen.

Bone marrow niches for hematopoietic stem cells

HemaSphere
AbstractHematopoietic stem cells (HSCs) are the cornerstone of the hematopoietic system. HSCs sustain the continuous generation of mature blood derivatives while self‐renewing to preserve a relatively constant pool of progenitors throughout life. Yet, long‐term maintenance of functional HSCs exclusively takes place in association with their native ...

Cold Atmospheric Plasma‐Activated Decellularized Extracellular Matrix Gel as a Tumor‐Infiltrating Immunoactivation Platform for Post‐Surgical Cancer Immunotherapy

Advanced Materials, EarlyView.
An injectable cold atmospheric plasma‐activated decellularized tumor extracellular matrix hydrogel is introduced as a post‐surgical immunoactivation platform. The engineered gel attracts residual tumor cells and induces immunogenic cell death, reshaping the tumor microenvironment and eliciting systemic antitumor immunity. In combination with checkpoint

"Studies on the cardiomyocytic potential of dermal stem cells” [PDF]

, 2008
In Europe, diseases of the heart and circulatory system are the main cause of death; 48% of all deaths are from coronary heart disease, accounting for over 4.30 million deaths each year (European cardiovascular disease statistics 2008). Identifying stem

Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

Advanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

The regulation of haemopoietic stem cell and progenitor cell proliferation by humoral factors

, 2012
The mechanisms which regulate the growth fraction of the haemopoietic stem cell (CFU-S) and granulocyte macrophage progenitor cell (GM-CFC) have been investigated.
