Objective to investigate effects of PDGF on phenotypic change of glomerular mesangial cells (MC), and study intracellular mechanisms through mitogen-activated - protein kinase (MAPK) pathways.

There's a scientific word for this: phenotypic plasticity, the ability of an individual to change its traits to adapt to its environment.

Dynamic traits are those phenotypic values change with time and other quantifiable factors such as age, parities, physiological status, performance level and environment etc.
