Abstract Mechanical forces are critical to embryogenesis, specifically, in the lineage-specification gastrulation phase, whereupon the embryo is transformed from a simple spherical ball of cells to a multi-layered organism, containing(More)
The mechanisms underlying early islet graft failure are not entirely clear, but are thought to involve ischemic injury due to delayed vascularization. We hypothesize that blood vessels play an active role in cell-cell communications supporting islet survival and engraftment. To test this hypothesis and to uncouple endothelial cell (EC)-generated signaling(More)
Implantable 3D engineered vascular tissue constructs can be formed by co-culturing endothelial and fibroblast cells on macroporous scaffolds. Here we show that these constructs can be used for studying the dynamics of neovascular formation in-vitro by a combination of live confocal imaging and an array of image processing and analysis tools, revealing(More)
PURPOSE Infantile aphakic glaucoma may develop as a postoperative complication of early childhood cataract surgery. It has been associated with risk factors including surgery in early life and retained lens material; however, its cause and mechanism are poorly understood. This study focused on the potential role of retained lens material (specifically,(More)
Adipose-derived mesenchymal stem cells (MSCs) have been gaining fame mainly due to their vast clinical potential, simple isolation methods and minimal donor site morbidity. Adipose-derived MSCs and microvascular endothelial cells have been shown to bear angiogenic and vasculogenic capabilities. We hypothesized that co-culture of human adipose-derived MSCs(More)
Human embryonic and induced pluripotent stem cells (hESC/hiPSC) are promising cell sources for the derivation of large numbers of specific cell types for tissue engineering and cell therapy applications. We have describe a directed differentiation protocol that generates fibroblasts from both hESC and hiPSC (EDK/iPDK) that support the repair and(More)
