The Golgi apparatus (GA) is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons. The GA is often considered the distribution and shipping department for the cell’s chemical products. This book traces the first 100 years of GA discovery from the first published accounts from Pavia, Italy, in 1898 to the Centenary Celebration in Pavia, Italy, in 1998 to our most recent discoveries. It summarizes the past 50 years beginning with the modern era of GA discovery, leading up to the present era with almost exclusive focus on molecular biology.
