Synthesis of Hormones

A researcher is interested in studying the synthesis of peptide and steroid hormones. She harvests 5 samples of cells from different hormone-producing organs of the body and allows each sample of cells (Cell Types 1-5) to synthesize its hormones for a period of time. Afterwards, she measures the intracellular concentration of the hormones synthesized in each Cell Type. The results are displayed in the corresponding chart. Based on the information provided, where would Cell Type 2 possibly be found in the human body?
