Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.
Integrins are the main principal receptors used by the cells of animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.
