blastema การใช้

• Those stem cells form a mound called a blastema and multiply rapidly.
• Segmental regeneration in these animals is epimorphic and occurs through blastema formation.
• Wilms tumor is a malignant tumor containing metanephric blastema, stromal and epithelial derivatives.
• The two cases reported by Posalaki et al . showed blastema, glomeruli and tubuli.
• Instead of originating from the metanephrogenic blastema, the collecting duct originates from the ureteric bud.
• Signals released from the ureteric bud induce the differentiation of the metanephrogenic blastema into the renal tubules.
• The role of BMP7 in mammalian kidney development is through induction of MET of the metanephrogenic blastema.
• The system of tissue induction between the ureteric bud and the metanephric blastema is a reciprocal control system.
• The connecting tubule derives from the metanephric blastema, but the rest of the system derives from the ureteric bud.
• In epimorphosis stem cells either from a reserve pool or those produced by dedifferentiation form a blastema and generate new tissues.
• The portion of undifferentiated intermediate mesoderm in contact with the tips of the branching ureteric bud is known as the metanephrogenic blastema.
• A salamander can not only regenerate a mesenchymal cells, and the blastema functions as a self-organizing system to regenerate the limb.
• Horestein et al . reported a lumbosacral nephrogenic rest including blastema ( mature tubules and nephrons ) in abundant stroma unassociated to spinal dysraphism.
• 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.
• In one experiment, T . H . Morgan found that a piece corresponding to 1 / 279th of a planarian After amputation, stump cells form a blastema formed from neoblasts, pluripotent cells found throughout the planarian body.
• GDNF, gonadal derived neurotrophic factor, is produced by the metanephric blastema and is essential in binding to the Ret receptor on the ureteric bud, which bifurcates and coalesces as a result to form the renal pelvis, major and minor calyces and collecting ducts.
• Virchow was the first to correctly link the origin of cancers from otherwise normal cells . ( His teacher M黮ler had proposed that cancers originated from cells, but from special cells, which he called blastema . ) In 1855, he suggested that cancers arise from the activation of dormant cells ( perhaps similar to cells now known as stem cells ) present in mature tissue.
