The attachment of cells to collagen has been reported previously to require the presence of serum and the particular serum protein involved in this process, variously known as CIG, CAP or fibronectin, has been isolated. This conclusion that cell attachment to collagen requires serum (or more precisely, fibronectin) is based on experiments measuring the kinetics of cell attachment to films of co...

A form of microscopy that utilizes a photonic crystal biosensor surface as a substrate for cell attachment enables label-free, quantitative, submicron resolution, time-resolved imaging of cell-surface interactions without cytotoxic staining agents or temporally-unstable fluorophores. Other forms of microscopy do not provide this direct measurement of live cell-surface attachment localization an...

The insulin-like growth factor binding proteins (IGFBPs) have IGF-independent differential effects on cell function. We investigated whether they can affect integrin-receptor-mediated cell attachment to different extracellular matrix (ECM) components in Hs578T cells. Cell attachment to a general ECM gel was unaffected by IGFBP-1 and -6 but was significantly increased by IGFBP-4 and -5 and decre...

Using fast Fourier transform (FFT) analysis, we previously observed that cells within Escherichia coli biofilm are organized in nonrandom or periodic spatial patterns. Here, we developed a gravity displacement assay for examining cell adherence and used it to quantitatively monitor the formation of two distinct forms of cell attachment, temporary and permanent, during early biofilm development....

Objective(s):Anodized treated titanium surfaces, have been proposed as potential surfaces with better cell attachment capacities. We have investigated the adhesion and proliferation properties of H9C2 cardiac myoblasts on anodized treated titanium surface.  Materials and Methods: Surface topography and anodized tubules were examined by high-resolution scanning electron microscopy (SEM). Contro...

Primary melanocytes attach poorly to collagen type IV and laminin, in contrast to their firm attachment to collagen type I/III and fibronectin [Gilchrest et al., In vitro (Rockville), 21: 114-120, 1985]. We have now found that metastatic B16 melanoma cells attach well to collagen type IV, laminin, vitronectin, and fibronectin but show a selective defect in attachment and cell aggregation on nat...
