Manganese-dependent cell-substratum adhesion.
In the presence of manganese, baby hamster kidney cells attached and spread on substrata without added adhesion factors (e.g., fibronectin, lectins). This Mn-dependent adhesion occurred even when the substratum was coated with proteins, such as albumin, haemoglobin, immunoglobulin or ovalbumin, or a dried collagen film. Under similar conditions, cells without Mn in Mg/Ca-containing medium attac...
متن کاملInnate Non-Specific Cell Substratum Adhesion
Adhesion of motile cells to solid surfaces is necessary to transmit forces required for propulsion. Unlike mammalian cells, Dictyostelium cells do not make integrin mediated focal adhesions. Nevertheless, they can move rapidly on both hydrophobic and hydrophilic surfaces. We have found that adhesion to such surfaces can be inhibited by addition of sugars or amino acids to the buffer. Treating w...
متن کاملCalreticulin affects focal contact-dependent but not close contact-dependent cell-substratum adhesion.
We used two cell lines expressing fast (RPEfast) and slow (RPEslow) attachment kinetics to investigate mechanisms of cell-substratum adhesion. We show that the abundance of a cytoskeletal protein, vinculin, is dramatically decreased in RPEfast cells. This coincides with the diminished expression level of an endoplasmic reticulum chaperone, calreticulin. Both protein and mRNA levels for calretic...
متن کاملCell-to-substratum adhesion and guidance of axonal elongation.
The behavior of axonal growth cones on surfaces with patterned variations in substratum was observed. Cells from sensory ganglia of 8-day-old chicken embryos were cultured on plastic petri dishes, plastic tissue culture dishes, and polyornithine-coated tissue culture dishes, all of which contained gridlike patterns of palladium (Pd) deposition. The results indicated that growth cones elongated ...
متن کاملCell Substratum Adhesion during Early Development of Dictyostelium discoideum
Vegetative and developed amoebae of Dictyostelium discoideum gain traction and move rapidly on a wide range of substrata without forming focal adhesions. We used two independent assays to quantify cell-substrate adhesion in mutants and in wild-type cells as a function of development. Using a microfluidic device that generates a range of hydrodynamic shear stress, we found that substratum adhesi...
