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 ...

Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

open access: yesAdvanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore

Keloids: Current and emerging therapies

open access: yesScars, Burns & Healing, 2020
Keloids are pathological scars that grow over time and extend beyond the initial site of injury after impaired wound healing. These scars frequently recur and rarely regress. They are aesthetically disfiguring, can cause pain, itching, discomfort as well
