Exempel på hur man kan använda BLASTEMA i en mening

• Wilms' tumor is a malignant tumor containing metanephric blastema, stromal and epithelial derivatives.
• In short, the term blastema started being used to refer to what modern embryologists increasingly began calling a rudiment or Anlage.
• For regeneration the salamander tissues form a blastema by de-differentiation of mesenchymal cells, and the blastema functions as a self-organizing system to regenerate the limb.
• The metanephrogenic blastema or metanephric blastema (or metanephric mesenchyme, or metanephric mesoderm) is one of the two embryological structures that give rise to the kidney, the other being the ureteric bud.
• This often develops as the result of splitting of the nephrogenic blastema, or from separate metanephric blastemas into which partially or completely reduplicated ureteral stalks enter to form separate capsulated kidneys; in some cases the separation of the reduplicated organ is incomplete (fused supernumerary kidney).
• It is embryologically derived from the metanephrogenic blastema, the same tissue that gives rise to nephroblastomatosis and Wilms tumor.
• In some contexts, the primary division is at the border of kidney and ureter, and in other contexts, the primary division is between derivatives of the metanephric blastema and those of the ureteric bud.
• The shift in Hox gene expression in the blastema during posterior regeneration is indicative of limited morphallaxis, in addition to epimorphic regeneration.
• Epimorphosis is defined as the regeneration of a specific part of an organism in a way that involves extensive cell proliferation of somatic stem cells, dedifferentiation, and reformation, as well as blastema formation.
• Just as plant cells respond to injury by undergoing callus formation via dedifferentiation, some animal models dedifferentiate their cells to form blastema, which are analogous to plant calluses, after limb amputation.
