Tissue engineering whole bones through endochondral ossification: Regenerating the distal phalanx

Tissue engineering whole bones through endochondral ossification: Regenerating the distal phalanx
(2015)
BUCKLEY, CONOR; KELLY, DANIEL
Abstract:
Novel strategies are urgently required to facilitate regeneration of entire bones lost due to trauma or disease. In this study, we present a novel framework for the regeneration of whole bones by tissue engineering anatomically shaped hypertrophic cartilaginous grafts in vitro that subsequently drive endochondral bone formation in vivo. To realize this, we first fabricated molds from digitized images to generate mesenchymal stem cell-laden alginate hydrogels in the shape of different bones (the temporomandibular joint [TMJ] condyle and the distal phalanx). These constructs could be stimulated in vitro to generate anatomically shaped hypertrophic cartilaginous tissues that had begun to calcify around their periphery. Constructs were then formed into the shape of the distal phalanx to create the hypertrophic precursor of the osseous component of an engineered long bone. A layer of cartilage engineered through self-assembly of chondrocytes served as the articular surface of these const...

Transmembrane Peptides Stabilize Inverted Cubic Phases in a Biphasic Length-dependent Manner: Implications for Protein-induced Membrane Fusion.
(2006)
CAFFREY, MARTIN
Abstract:
WALP peptides consist of repeating alanine-leucine sequences of different lengths, flanked with tryptophan ``anchors?? at each end. They form membrane-spanning a-helices in lipid membranes, and mimic protein transmembrane domains. WALP peptides of increasing length, from 19 to 31 amino acids, were incorporated into N-monomethylated dioleoylphosphatidylethanolamine (DOPE-Me) at concentrations up to 0.5 mol%peptide.When pure DOPE-Me is heated slowly, the lamellar liquid crystalline (La) phase first forms an inverted cubic (QII) phase, and the inverted hexagonal (HII) phase at higher temperatures. Using time-resolved x-ray diffraction and slow temperature scans (1.5 C/h), WALP peptides were shown to decrease the temperatures of QII and HII phase formation (TQ and TH, respectively) as a function of peptide concentration. The shortest and longest peptides reduced TQ the most, whereas intermediate lengths had weaker effects. These findings are relevant to membrane fusion because the first...

Veins improve fracture toughness of insect wings
(2012)
TAYLOR, DAVID
Abstract:
During the lifetime of a flying insect, its wings are subjected to mechanical forces and deformations for millions of cycles. Defects in the micrometre thin membranes or veins may reduce the insect's flight performance. How do insects prevent crack related material failure in their wings and what role does the characteristic vein pattern play? Fracture toughness is a parameter, which characterises a material's resistance to crack propagation. Our results show that, compared to other body parts, the hind wing membrane of the migratory locust S. gregaria itself is not exceptionally tough (1.04?0.25 MPa?m). However, the cross veins increase the wing's toughness by 50% by acting as barriers to crack propagation. Using fracture mechanics, we show that the morphological spacing of most wing veins matches the critical crack length of the material (1132 ?m). This finding directly demonstrates how the biomechanical properties and the morphology of locust wings are functionally...

Zinc-dependent mechanical properties of Staphylococcus aureus biofilm-forming surface protein SasG

Zinc-dependent mechanical properties of Staphylococcus aureus biofilm-forming surface protein SasG
(2016)
GEOGHEGAN, JOAN; FOSTER, TIMOTHY
Abstract:
Staphylococcus aureus surface protein SasG promotes cell-cell adhesion during the accumulation phase of biofilm formation, but the molecular basis of this interaction remains poorly understood. Here, we unravel the mechanical properties of SasG on the surface of living bacteria, that is, in its native cellular environment. Nanoscale multiparametric imaging of living bacteria reveals that Zn(2+) strongly increases cell wall rigidity and activates the adhesive function of SasG. Single-cell force measurements show that SasG mediates cell-cell adhesion via specific Zn(2+)-dependent homophilic bonds between ?-sheet-rich G5-E domains on neighboring cells. The force required to unfold individual domains is remarkably strong, up to ?500 pN, thus explaining how SasG can withstand physiological shear forces. We also observe that SasG forms homophilic bonds with the structurally related accumulation-associated protein of Staphylococcus epidermidis, suggesting the possibility of multispecies bi...
