where are leydig cells located what do they secrete
Leydig cell Leydig cells, also known as interstitial cells of Leydig, are found adjacent to the seminiferous tubules in the testicle. They produce testosterone in the presence of luteinizing hormone (LH). Leydig cells are polyhedral in shape, display a large prominent nucleus, an eosinophilic cytoplasm and numerous lipid-filled vesicles.
Goblet cell Goblet cells are typically found in the respiratory, reproductive and gastrointestinal tracts and are surrounded by stratified squamous cells.[1] Differentiation of epithelial cells into goblet cells plays a key role in the excessive mucus production seen in many diseases, such as asthma and cancer.
