Detection of growth hormone-producing cells in human thymus by immunohistochemistry and non-radioactive in situ hybridizationN Maggiano, M Piantelli, R Ricci, LM Larocca, A Capelli and FO Ranelletti Department of Pathology, Universita Cattolica del Sacro Cuore, Rome, Italy. It is well recognized that growth hormone (GH) may act as a growth and differentiation factor for the thymus gland. Recently, it has been reported that Pit-1/GHF-1 transcription factor, which controls the expression of both GH and prolactin, is expressed in stromal (not lymphoid) cells of human thymus. Here, we demonstrated by immunohistochemistry and in situ hybridization the presence of distinct GH-producing epithelial cell subsets in human thymus. The cells positive for GH mRNA and GH-immunoreactive substance are both located in the same thymus compartments, i.e., along the thymus capsule, in the subcapsular cortex, and within the septa. Local concentration of GH higher than systemic ones, in combination with other factors, may be important in regulating the thymic microenvironment necessary for T- lymphocyte differentiation.
