IGF-1 is made in response to growth hormone and is needed for growth hormone to have its effects on muscles and other tissues. Growth hormone, synthesized in the pituitary gland, travels to the liver, which then responds by producing IGF-1.
Spring City is a borough in Chester County, Pennsylvania, United States. The population was 3,323 at the 2010 census. Spring City is a member of the Spring-Ford Area School District.

While the name Spring is applied to a large area of NW Harris County, the town of Spring is located at the intersection of Spring-Cypress and Hardy Roads and encompasses a relatively small area of perhaps 1 sq.km. The large geographic area now known as Spring was originally inhabited by the Orcoquiza Native Americans. In 1836 the Texas General Council of the Provisional Government placed what is now the town of Spring in the Harrisburg municipality. In 1838 William Pierpont placed a trading post on Spring Creek. In 1840 the town of Spring had 153 residents.
