M. Thornwall et al., IMMUNOHISTOCHEMICAL DETECTION OF THE MELANOCORTIN-1 RECEPTOR IN HUMANTESTIS, OVARY AND PLACENTA USING SPECIFIC MONOCLONAL-ANTIBODY, Hormone research, 48(5), 1997, pp. 215-218
We describe the immunohistochemical detection of the melanocortin 1 re
ceptor (MC1R) protein in human gonadal tissues using a specific monocl
onal antibody. The MC1R was found to be present in Leydig's cells in t
estis, in lutein cells in the corpus luteum and in the nucleus of the
trophoblastic cells of the placenta. Though it has been speculated ear
lier that MC1R is present in gonadal tissues, this is the first report
demonstrating the presence of MC1R protein in these cells.
