The cultured cell pellets were harvested on day 14 and evaluated histologically by Safranin O staining, and scored on the basis of staining intensity, cell-to-cell distance, and cell morphology, according to a pellet scoring system [ 32] (Fig. 6a).
The biochemical basis of cell differentiation is the synthesis by the cell of a particular set of proteins, carbohydrates, and lipids.
Cell positioning is an essentially important technique, since it is the basis of cell array and single cell analysis in biomedical research.
The activity of Stx, which was measured on the basis of cell toxicity of Stx to HEp-2 cells, was significantly inhibited, as compared with no treatment (0 min), by 30 min of nitrogen gas plasma treatment using BLP-TES (*p < 0.05, **p < 0.01).
Protein-protein interactions are the molecular basis of cell signaling.
Biomimetic models of cell surfaces were designed to study the physical basis of cell adhesion.
The limited proliferation potential of primary MECs causes significant technical problems for dissecting the molecular basis of cell cycle control in these cells.
While the molecular machinery governing the development of hair cells has received much attention [1], [2] far less is known about the molecular basis of cell fate decision in supporting cells [3], [4].
In 1997, Asahara et al. [1] reported the isolation of putative endothelial progenitor cells (EPC) from human peripheral blood on the basis of cell surface expression of haematopoietic stem cell (CD34) or kinase insert domain receptor (KDR) markers.
We confirmed that the hiPSCs cultured under defined conditions were pluripotent stem cells on the basis of cell morphology, growth rate, the expression of self-renewal genes, cell differentiation in vitro, and teratoma formation in vivo.
Here, we quantitatively account for this wing-blade shape change on the basis of cell divisions, cell rearrangements and cell shape changes.
