Extracellular matrix can regulate multipotent mesenchymal stromal cells (MMSC) differentiation, with potential applications for tissue engineering. A relief of mineralized bone takes essential effect on MMSC fate. Nevertheless, delicate structure and a hierarchy of niches for stromal stem cells and its quantitative parameters are not practically known. Here, we describe the protocol to define the basic approach providing a guiding for in vitro identification of quantitative features of artificial calcium phosphate niches which promotes osteogenic differentiation and maturation of stromal stem cell.

Poetam and anaferon (pediatric formulation) administered in combination with iron preparation to patients with anemia induce pronounced positive shifts in metabolic and morphological status of mature erythrocytes: the number of sulfhydryl groups and lipoprotein complexes in cell membranes and dry weight of erythrocytes increased, while the number of forms at different stages of degeneration decreased.
