Spatiotemporally Controllable and Cytocompatible Approach Builds 3D Cell Culture Matrix by Photo-Uncaged-Thiol Michael Addition Reaction|
A new concept of photocrosslinking mechanism is developed to construct a 3D cell culture matrix based on a photo-uncaged-thiol Michael addition. [Adv Mater]
The Chemokine Receptor CXCR6 Contributes to Recruitment of Bone Marrow-Derived Fibroblast Precursors in Renal Fibrosis
As chemokines mediate the trafficking of circulating cells to sites of injury, scientists studied the role of CXCR6 in mouse models of renal injury. Significantly, the kidney of CXCR6 knockout mice accumulated fewer bone marrow-derived fibroblasts in response to injury, expressed less profibrotic chemokines and cytokines, displayed fewer myofibroblasts, and expressed less α-smooth muscle actin in the obstructed kidneys compared with wild-type mice.

Strain-Dependent Modulation of Macrophage Polarization within Scaffolds
Implanted synthetic substrates for the regeneration of cardiovascular tissues are exposed to mechanical forces that induce local deformation. Circulating inflammatory cells, actively participating in the healing process, will be subjected to strain once recruited. The authors investigated the effect of deformation on human peripheral blood mononuclear cells adherent onto a scaffold, with respect to macrophage polarization towards an inflammatory and reparative phenotype and to early tissue formation.

Stringent Requirement for Spatial Arrangement of Extracellular Matrix in Supporting Cell Morphogenesis and Differentiation
Investigators found that tendon sections can be viewed as a pre-formed block of extracellular matrix in which the collagen fibrils exhibited a spatial regularity unraveled in any artificially constructed scaffold. By carving the tendon at different angles relative to its main axis, they created different surfaces with distinct spatial arrangements of collagen fibrils. [BMC Cell Biol]
MiR-29b Inhibits Collagen Maturation in Hepatic Stellate Cells through Down-Regulating the Expression of HSP47 and Lysyl Oxidase
Heat shock protein 47 (HSP47) and lysyl oxidase (LOX) are known to be essential for extracellular matrix (ECM) maturation. Scientists demonstrated that expression of HSP47 and LOX was significantly up-regulated in culture-activated primary rat hepatic stellate cells, TGF-β stimulated LX-2 cells and liver tissue of CCl4-treated mice, which was accompanied by a decrease of miR-29b level.

Comparative Performance of Collagen Nanofibers Electrospun from Different Solvents and Stabilized by Different Crosslinkers
Collagen type I was successfully electrospun from two different solvents, trifluoroethanol and dilute acetic acid. Characterization of collagen fibers was performed by means of SEM, ATR-IR, Circular Dichroism and WAXD. [J Mater Sci Mater Med]
The Influence of Selected Flavonoids from the Leaves of Cirsium palustre (L.) Scop. on Collagen Expression in Human Skin Fibroblasts
Ten flavonoids belonging to the subclasses of flavones, flavanones and aurones were isolated from methanolic extract of Cirsium palustre leaves after multistep chromatographic separation. Four compounds-eriodictyol 7-O-glucoside, 6-hydroxyluteolin 7-O-glucoside, scutellarein 7-O-glucoside and pedalitin-were tested for their effect on collagen expression in normal human dermal fibroblasts.

Effects of Various Extracellular Matrix Proteins on the Growth of HL-1 Cardiomyocytes
Researchers present the physical and biochemical effects of extracellular matrices (ECMs) on HL-1 cardiomyocytes. ECMs play major roles in cell growth, adhesion and the maintenance of native cell functions. [Cells Tissues Organs]
Matricellular Proteins and Biomaterials|
Expression of matricellular proteins is modulated during the foreign body response and these proteins interact with biomaterials. The design of biomaterials to specifically alter the levels of matricellular proteins surrounding implants provides a new avenue for the design and fabrication of biomimetic biomaterials.
