Biomimetic Scaffolds with Dual Gradients of Biological Effectors for Tendon‐to‐Bone Repair

open access: yesAdvanced Healthcare Materials, EarlyView.
The authors have developed a biomimetic scaffold with dual gradients through a diffusion‐driven method. The scaffold features funnel‐shaped microchannels for cell infiltration, while the dual gradients synergetically induce the graded differentiation of mesenchymal stem cells into osteoblasts, chondrocytes, and tenocytes, allowing for a seamless ...

Nanomedicine Approaches for Corneal Diseases

open access: yesJournal of Functional Biomaterials, 2015
Corneal diseases are the third leading cause of blindness globally. Topical nonsteroidal anti-inflammatory drugs (NSAIDs), steroids, antibiotics and tissue transplantation are currently used to treat corneal pathological conditions.

Combining Fine- and Coarse-Grained Classifiers for Diabetic Retinopathy Detection

open access: yes, 2020
Visual artefacts of early diabetic retinopathy in retinal fundus images are usually small in size, inconspicuous, and scattered all over retina. Detecting diabetic retinopathy requires physicians to look at the whole image and fixate on some specific ...

E2F1 Suppresses Oxidative Metabolism and Endothelial Differentiation of Bone Marrow Progenitor Cells [PDF]

open access: yes, 2018
RATIONALE: The majority of current cardiovascular cell therapy trials use bone marrow progenitor cells (BM PCs) and achieve only modest efficacy; the limited potential of these cells to differentiate into endothelial-lineage cells is one of the major ...

Development of a Vaginal Extracellular Matrix Hydrogel for Combating Genitourinary Syndrome of Menopause

open access: yesAdvanced Materials, EarlyView.
In this study, a vaginal specific ECM hydrogel (vECM) is developed, optimized for intravaginal topical administration, and evaluated for mitigatation of vaginal atrophy associated with menopause. When applied in a rat model of menopause, vECM improves vaginal epithelial thickness and stem cell phenotype, and despite topical application, vECM also ...

Cholinergic neural activity directs retinal layer-specific angiogenesis and blood retinal barrier formation. [PDF]

open access: yes, 2019
Blood vessels in the central nervous system (CNS) develop unique features, but the contribution of CNS neurons to regulating those features is not fully understood. We report that inhibiting spontaneous cholinergic activity or reducing starburst amacrine

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Relevance of monocytic features for neovascularization capacity of circulating endothelial progenitor cells [PDF]

open access: yes, 2003
Background— Transplantation of ex vivo expanded circulating endothelial progenitor cells (EPCs) from peripheral blood mononuclear cells improves the neovascularization after critical ischemia. However, the origin of the endothelial progenitor lineage and
