Sacrificial strategy towards the formation of vascular‐like networks in volumetric tissue constructs

BMEMat, EarlyView.
This mini‐review highlights the latest progress in the sacrificial template‐enabled creation of patent vascular‐like networks, which can be incorporated into volumetric tissue constructs. Such microchannel networks can provide an immediate supply of nutrition and O2 to those cells residing next to the channels.

CARS and SHG microscopy to follow the collagen production in living human corneal fibroblasts and mesenchymal stem cells in fibrin gel 3D cultures [PDF]

, 2011
Coherent anti-Stokes Raman scattering (CARS) microscopy is combined with second harmonic generation (SHG) technique in order to follow the early stage of stem cell differentiation within a 3D scaffold. CARS microscopy can detect lipid membranes and droplet compartments in living cells and SHG microscopy enables a strong imaging contrast for molecules ...

Blood clot inspired pore‐gradient nanofiber sponge with “outer filtration” and “inner adsorption” bifunction for rapid stop of uncontrolled hemorrhage

BMEMat, EarlyView.
In this study, by mimicking the nanofiber structure and netting blood cells function of fibrin network in blood clots, we developed a novel bioinspired quaternized chitosan nanofiber sponge with distinct blood cell filtration and blood plasma absorption bifunction for rapid hemostasis.

Binding of thrombin-activated platelets to a fibrin scaffold through α(IIb)β₃ evokes phosphatidylserine exposure on their cell surface. [PDF]

PLoS ONE, 2013
Recently, by employing intra-vital confocal microscopy, we demonstrated that platelets expose phosphatidylserine (PS) and fibrin accumulate only in the center of the thrombus but not in its periphery.

Effect of suturing in root coverage via coronally advanced flaps: A systematic review

Clinical Advances in Periodontics, EarlyView.
Abstract Background To analyze the evidence about the influence of the suturing technique and material in terms of the percentage of mean root coverage (%MRC) following root coverage therapy in teeth diagnosed with single/localized gingival recession defects (GRD) via a monolaminar coronally advanced flap. Methods The protocol of this systematic review

In vitro ultrastructure and biodegradation of activated plasma albumin gel derived from human samples: A prospective observational study

Clinical Advances in Periodontics, EarlyView.
Abstract Background In soft tissue regeneration, the clinical efficacy of fibrin membranes has been a pressing concern. The key to this efficacy lies in the stability of membrane and its controlled absorption. Human serum albumin, with its influence on the formation and stability of fibrin networks, could hold the key to developing a more stable ...

Multi-scale strain-stiffening of semiflexible bundle networks [PDF]

arXiv, 2012
Bundles of polymer filaments are responsible for the rich and unique mechanical behaviors of many biomaterials, including cells and extracellular matrices. In fibrin biopolymers, whose nonlinear elastic properties are crucial for normal blood clotting, protofibrils self-assemble and bundle to form networks of semiflexible fibers.
