An appropriate cell microenvironment is key to tissue engineering and regenerative medicine. Revealing the factors that influence a fundamental research topic in fields of biology, biomaterials, engineering, The consists not only its surrounding cells soluble factors, but also extracellular matrix (ECM) or nearby external biomaterials regeneration. This review focuses on six aspects biomaterial–related microenvironments: ① chemical composition materials, ② material dimensions architecture, ③...
From the inside out: Hollow ferrocenyl coordination polymer microspheres with microporous shells were prepared by a convenient and template-free approach. An Ostwald ripening mechanism is responsible for formation of hollow cavities. The hierarchically have potential applications in catalysis, drug delivery, hydrogen storage.
Abstract Cartilage is difficult to self‐repair and it more challenging repair an osteochondral defects concerning both cartilage subchondral bone. Herein, hypothesized that a bilayered porous scaffold composed of biomimetic gelatin hydrogel may, despite no external seeding cells, induce regeneration in vivo after being implanted into mammal joints. This idea confirmed based on the successful continuous 3D‐printing scaffolds combined with sol‐gel transition aqueous solution derivative...

The were fabricated compression molding/particle leaching plasma-treated surface deposition. pore morphology, mechanical properties, deposition scaffold characterized, growth bone marrow derived mesenchymal...
Abstract The malalignment of teeth is treated classically by metal braces with alloy wires, which has an unfavorable influence on the patients appearance during treatment. With development digitization, computer simulation and three-dimensional (3D) printing technology, herein, a modern treatment was tried using clear polymeric aligners, were fabricated molding polyurethane films via thermoforming 3D-printed personalized dental models. key parameters photocurable 3D models mechanical...
The treatment of cartilage injury and osteoarthritis has been a classic problem for many years. idea in situ tissue regeneration paves way osteochondral repair vivo. Herein, hydrogel scaffold linked with bioactive peptides that can selectively adsorb transforming growth factor β1 (TGF-β1) was hypothesized to not only afford cell ingrowth space but also induce the endogenous TGF-β1 recruitment chondrogenesis promotion. In this study, bilayered porous scaffolds gelatin methacryloyl (GelMA)...
Surface topography is a biophysical factor affecting cell behaviors, yet the underlying cues are still not clear. Herein, we hypothesized that stereo coverage and overall stiffness of biomaterial arrays on scale single cells underly parts effects adhesion. We fabricated series microarrays (micropillar, micropit, microtube) poly(l-lactic acid) (PLLA) using mold casting based pre-designed templates. The characteristic sizes array units were less than cell, thus, each could sense micropatterns...
While various porous scaffolds have been developed, the focused study about which structure leads to better mechanics is rare. In this study, we designed with tetragonal, hexagonal and wheel-like structures under a given porosity, fabricated corresponding poly(lactic acid) (PLA) three-dimensional printing. High-resolution micro-computed tomography was carried out calculate their experimental porosity confirm high interconnectivity. The theoretical compressive properties in longitudinal...
With the ageing of population and increase sports injuries, number joint injuries has increased greatly. Tissue engineering or tissue regeneration is an important method to repair articular cartilage defects. While it recently been paid much attention use bilayered porous scaffolds both subchondral bone, interesting examine what extent a bilayer scaffold composed same kind biodegradable polymer poly(lactide-co-glycolide) (PLGA) can restore osteochondral defect. Herein, we fabricated PLGA...
Enabling a biodegradable polymer radiopaque under X-ray is much desired for many medical devices. Physical blending of present and commercialized contrast agent convenient yet lacks comprehensive fundamental research. Herein, we prepared polymer-based raw material by poly(l-lactic acid) (PLLA or simply PLA) iohexol (IHX), where PLA constituted the continuous phase IHX particles served as dispersed phase. The strong adsorption enabled composite radiopaque; hydrolysis polyester water...
Abstract With the development of tissue engineering and regenerative medicine, it is much desired to establish bioimaging techniques monitor real-time regeneration efficacy in vivo a non-invasive way.

After summary T2 mapping T1-related delayed gadolinium-enhanced MRI (dGEMRIC) vitro...
Directed migration of cells through cell-surface interactions is a paramount prerequisite in biomaterial-induced tissue regeneration. However, whether and how the nanoscale spatial gradient adhesion molecules on material surface can induce directed not sufficiently known. Herein, we employed block copolymer micelle nanolithography to prepare gold nanoarrays with nanospacing gradient, which were prepared by continuously changing dipping velocity. Then, self-assembly monolayer technique was...
