Tissues grown in gels (IMAGE)
Caption
Dissected frog brain tissues were cultured in gels of different stiffness (soft: red, stiff: yellow), the expression of key chemical signals increased in gels of higher stiffness. When soft parts of the developing frog brain were compressed and thereby stiffened, for a long time (6 hours), the expression of chemical signals were similarly increased.
