blastema

(51) From the seventeenth to nineteenth centuries, the lymph and blastema theories dominated the oncology landscape, contending that cancer was formed by the abnormal movement of fluid throughout the body and by small blastemas between pockets of tissue.

Bradshaw, "Acidic fibroblast growth factor is present in regenerating limb blastemas of axolotls and binds specifically to blastema tissues," Developmental Biology, vol.

The superficial muscle layer differentiates into three blastemas: radial, middle and ulnar blastemas.

She found blastemas, blobs of rapidly dividing immature cells, and evidence that a key protein layer, the extracellular matrix, breaks down, allowing tissues to regrow.

We observed lethality in blastemas regenerated within 5 days when exposed to E2 or BPA at concentrations greater than 1 ppm (data not shown).

Los blastemas cartilaginosos de la clavicula humana aparecen entre las 10 y 12 semanas de gestacion, en el tejido mesenquimatico condensado de los extremos del esbozo clavicular y crecen rapidamente.

When cut in half, the worms form blastemas similar in architecture to those seen when researchers amputate the limbs of a urodele.

This is in contrast to the transplantation methods used in amphibians, in which only the most proximal portions of the limbs or regeneration blastemas were inserted into the body.

Like that of urodeles, the process can be categorized into the following steps: (1) wound closure and healing, (2) formation of wound epidermis, (3) formation of proliferative blastema cells, and (4) cellular differentiation and morphogenesis that leads to tissue restoration (Akimenko et al, 2003; Fig.
