Engineering Volumetric Tissue Analogs via Assembly of Endothelial Cell‐Covered Spheroidal Microtissues

open access: yesAdvanced Healthcare Materials, EarlyView.
An engineering strategy to fabricate highly vascularized volumetric tissues with capillary networks is developed. Endothelial cell‐covered spheroidal microtissues with high structural integrity are efficiently produced using bioprinting technology. These spheroidal microtissues are then assembled and cultured under perfusion conditions, resulting in ...

Arene Selectivity by a Flexible Coordination Polymer Host. [PDF]

open access: yes, 2016
The coordination polymers [Ag4 (O2 CCF3 )4 (phen)3 ]⋅phen⋅arene (1⋅phen⋅arene) (phen=phenazine; arene=toluene, p-xylene or benzene) have been synthesised from the solution phase in a series of arene solvents and crystallographically characterised.

3D Bioprinted Renal Constructs Using Kidney‐Specific ECM Bioink System on Kidney Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
A kidney‐specific bioink derived from decellularized porcine kidney tissue supports the encapsulation, viability, and maturation of human primary kidney cells within 3D bioprinted constructs. In vivo, it also promotes the recruitment of host renal progenitor cells, collectively enhancing structural and functional regeneration of renal tissue.
