These proteins interact to form complex signaling pathways that can have wide - reaching effects. (sciencedaily.com)
This has allowed them to determine one of the most complex signaling networks that control growth and development in response to environmental change. (salk.edu)
This is because the injected cells are not effective at transitioning into heart cells, as they require complex signals to make the change, which are absent in an adult heart. (gladstone.org)
