Calbindin-like immunoreactivity in epithelial cells of the newborn and adult human vomeronasal organ.

ABSTRACT

The vomeronasal organs (VNOs) of two humans, a male neonate and a female adult, were examined for immunolocalization of calbindin-D28k (calbindin) which has been immunolocalized to VNO receptor cells in other mammals. The present study demonstrates that epithelial cells within the VNOs of both subjects expressed calbindin-like immunoreactivity. These results suggest that human VNO epithelial cells of both genders express calbindin during development and in the adult.
