O QUE SIGNIFICA MORPHOGEN EM INGLÊS
Morfogênio
Um morfogênio é uma substância que regula o padrão de desenvolvimento de tecido no processo de morfogênese e as posições dos vários tipos de células especializadas dentro de um tecido. Mais precisamente, um morfogênio é uma molécula de sinalização que atua diretamente nas células para produzir respostas celulares específicas dependendo da sua concentração local. Uma vez que os morfogénios se difundem através dos tecidos de um embrião durante o desenvolvimento inicial, os gradientes de concentração são configurados. Esses gradientes conduzem o processo de diferenciação de células não especializadas em diferentes tipos de células, formando finalmente todos os tecidos e órgãos do corpo.
definição de morphogen no dicionário inglês
A definição de morfogênio no dicionário é um produto químico encontrado no tecido que influencia o desenvolvimento de células durante a morfogênese, formando um gradiente de concentração.

Life: The Science of Biology
Morphogen gradients provide positional information During development, the key
cellular question, "What am I (or what will I be)?" is often answered in part by "
Where am I?" Think of the cells in the developing nematode, which develop into ...

Shh and Gli Signalling in Development
To qualify as a morphogen, a signal must fulfil two criteria: to form a concentration
gradient, and to elicit distinct responses at different concentrations. Cells
encounter different concentrations of a morphogen according to their distance
from the ...

Signal Transduction Research Trends
Nickolas O. Grachevsky. Shh was first reported as a morphogen in the limb
development (Figure 2A). Classical grafting experiments using chick embryos
had revealed existence of zone of polarizing activity (ZPA) in the posterior limb
bud [41, ...

Biological Physics of the Developing Embryo
Here the effect of the morphogen spreads as if by diffusion, but what is actually
propagating across the domain is an activity passed from cell to cell by signaling
rather than by any substance (Reilly and Melton, 1996). In addition, morphogens
...

Patterning and Cell Type Specification in the Developing CNS ...
The concept of a morphogen can be traced to the turn of the twentieth century,
when Morgan postulated the presence of 'formative substances' as the basis for
differ- ent regeneration rates in worms (Morgan, 1901). Very soon thereafter,
Boveri ...
Normal morphogen gradient M with L (lower) and H (higher) thresholds for
Hoxa13 activation. Additional morphogen sources at the tip increase M to M1 or
M2. additional morphogen source is inserted at the distal tip, the gradient
increases to ...
Spyros Papageorgiou,
2007
By definition, a morphogen acts locally to organize the spatial pattern of cell
differention by virtue of spatial concentration differences. A high concentration of
a morphogen at location 1 specifies cell type or structure A, a lower concentration
at ...

Wnt Signaling in Development
As a minimal definition, an extracellular morphogen is a molecule that can
spread out from a localized source and directly instruct cell identities in a
concentration-dependent manner. For secreted signaling proteins to fulfill these
criteria ...
