CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Invasive Three-Dimensional Organotypic Neoplasia from Multiple Normal Human Epithelia
Researchers used tumor-associated genetic pathways to transform primary human epithelial cells from the epidermis, oropharynx, esophagus and cervix into genetically defined tumors in a human three-dimensional tissue environment that incorporates cell-populated stroma and intact basement membrane. [Nat Med]
 
Osteoblasts Derived from Induced Pluripotent Stem Cells Form Calcified Structures in Scaffolds Both In Vitro and In Vitro
Researchers performed directed differentiation to assess the ability of murine induced pluripotent stem cells to differentiate into bone, cartilage and fat in vitro and to maintain an osteoblast phenotype on a scaffold in vitro and in vivo. [Stem Cells]
 
Long-Term In Vitro Human Pancreatic Islet Culture Using Three-Dimensional Microfabricated Scaffolds
Researchers investigated the effects of human islet culture within various three-dimensional environments; collagen I gel, collagen I gel supplemented with extracellular matrix (ECM) components fibronectin and collagen IV, and microfabricated scaffold with ECM-supplemented gel. [Biomaterials]

In Vitro Generation of an Osteochondral Interface from Mesenchymal Stem Cell-Collagen Microspheres
Researchers present a mesenchymal stem cell-collagen microsphere-based approach for complex tissue engineering and demonstrate in vitro formation of a stem cell-derived osteochondral interface with calcified cartilage interface separating a non-calcified cartilage layer and an underlying bone layer. [Biomaterials]

High-Throughput Generation of Hydrogel Microbeads with Varying Elasticity for Cell Encapsulation
Researchers report a microfluidic approach for high-throughput generation of 3D microenvironments with different elasticity for studies of cell fate. [Biomaterials]

The Influence of Biological Motifs and Dynamic Mechanical Stimulation in Hydrogel Scaffold Systems on the Phenotype of Chondrocytes
Results support the hypothesis that both compressive strain and scaffold bioactivity have an important effect on the chondrocyte metabolic response to mechanical stimulation, and that the 3D environment surrounding chondrocytes can actively participate in translating mechanical stimulation to the resident cells. [Biomaterials]

Hydrogel-Electrospun Mesh Composites for Coronary Artery Bypass Grafts
Researchers demonstrated that a multi-component scaffold comprised of polyurethane electrospun mesh layers (intended to be mimetic of arterial collagen fiber loading) bonded together by a fibrin hydrogel matrix (intended to be mimetic of arterial elastic fiber response) results in a composite construct which retains the high tensile strength and suture retention strength of electrospun mesh but which displays a “J-shaped” mechanical response similar to that of native coronary artery. [Tissue Eng Part C Methods]

Distinct Regulatory Mechanisms Control Integrin Adhesive Processes During Tissue Morphogenesis
Researchers found that morphogenetic processes use various beta-integrin regulatory mechanisms to differing degrees and that conformational changes associated with outside-in activation are essential for developmental integrin functions. [Dev Dyn]
