Both cell-cell adhesion and oriented cell division play prominent roles in establishing tissue architecture, but it is unclear how they might be coordinated. Here, we demonstrate that the cell-cell adhesion protein E-cadherin functions as an instructive cue for cell division orientation. This is mediated by the evolutionarily conserved LGN/NuMA complex, which regulates cortical attachments of a...

Postoperative intra-abdominal adhesion is a very common complication after abdominal surgery. One clinical problem that remains to be solved is to identify an ideal strategy to prevent abdominal adhesions. Keratinocyte growth factor (KGF) has been proven to improve the proliferation of mesothelial cells, which may enhance fibrinolytic activity to suppress postoperative adhesions. This study inv...

Fibrous adhesions remain a major sequela of abdominal surgery. The proinflammatory peptide substance P (SP), known to participate in inflammatory events, may play a key role in adhesion formation. This hypothesis was tested by using an antagonist, CJ-12,255 (Pfizer), that blocks the binding of SP to the neurokinin 1 receptor (NK-1R). Adhesion formation was surgically induced in the peritoneum o...

While cell-substrate adhesions that form between the protruding edge of a spreading cell and flat surfaces have been studied extensively, processes that regulate the maturation of filopodia adhesions are far less characterized. Since little is known about how the kinetics of formation or disassembly of filopodia adhesions is regulated upon integration into the lamellum, a kinetic analysis of th...

background: endometriosis is a chronic inflammatory gynecologic disease. problems associated with endometriosis include dysmenorrhea dyspareunia and infertility. while endometriosis does not generally cause complications during pregnancy endometriosis clearly causes complications before pregnancy. cases: we report four patients with endometriosis who developed a hemoperitoneum during pregnancy ...

Adhesion-dependent cells actively sense the mechanical properties of their environment through mechanotransductory processes at focal adhesions, which are integrin-based contacts connecting the extracellular matrix to the cytoskeleton. Here we present first steps towards a quantitative understanding of focal adhesions as mechanosensors. It has been shown experimentally that high levels of force...

context in order to restore ovulation, puncturing ovaries with a needle powered by electricity, under laparoscopic observation, in women with anovulatory infertility with polycystic ovarian syndrome is called laparoscopic ovarian drilling (lod). although peri-adnexial adhesion after the surgery is inevitable, there is lack of evidence regarding the clinical significance. the objective of the pr...

Integrins assemble a complex network of molecular interactions at cell-matrix adhesion sites. Fluorescence correlation microscopy has now shed light on the spatial, temporal and numerical distributions of protein complexes during assembly and stabilization of nascent adhesions.
