when these cells are cultured on planar quartz , which is both chemically and physically isotropic , they flatten and adopt a morphology similar to that shown by cultured fibroblastic cell types on flat surfaces , suggesting that fin mesenchymal cells are not intrinsically predisposed to adopt an arborized morphology , like that observed in the intact fin bud .
