These 10 obvious propositions make a model of the specification of form, intended to expose underlying assumptions of developmental biology for examination and future experimentation. (I) The control of development is by means of local interactions, rather than global control mechanisms. (II) A macromolecule near a specific site will bind by mass action. (III) Starting with a precursor cell, al...

Despite the increasing number of scientific reports describing adhesion of Lactobacillus to components of the human intestinal mucosa, information on the surface molecules mediating this adhesion and their corresponding receptors is fragmentary. This MiniReview compiles present knowledge of the genetically and functionally characterized Lactobacillus factors responsible for mediating adhesion t...

background and objective: probiotics are live microbial feed supplements which beneficially affect the host animal by improving its intestinal microbial balance, producing metabolites which inhibit the colonization or growth of other microorganisms or by competing with them for resources such as nutrients or space. the aim of this study was to investigate the probiotic properties of candida fam...

Platelet activation and adhesion to the site of vascular injury is a dynamic process comprising reversible and irreversible phases. Platelet adhesion typically occurs in a multi-step process similar to the selectin/integrin-mediated adhesion of neutrophils. This phenomenon is highly regulated and influenced by the cross-talk between platelets and injured endothelium. This cross-talk involves a ...

Lactobacillus gasseri is one of the species, which has been considered as an oral probiotic. The probiotic characters, e.g., aggregation and adhesion abilities, may be affected by changes in environment. This study aimed to investigate effect cell surface components, some enzymes, pH, sugars, ions on (auto- coaggregation) abilities L. ability adhere epithelial cells. control group contained bac...

hematopoietic stem/progenitor cells (hspcs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. interacting factors such as stromal derived factor-1/cxcr4, very late antigen-4/vascular cell adhesion molecule-1, lymphocyte function-associated antigen-1/ intercellular adhesion molec...
