Flow Cytometric Analysis of Class I and II MHC Antigens on Ovine Luteal Cell Types
Secretion of progesterone by the corpus luteum (CL) is essential for the maintenance of early pregnancy in many species (1). The identification and characterization of two functionally and morphologically distinct types of steroidogenic luteal cells has provided several insights into the control of CL function (2). However, cells of the immune system may also play significant roles in the function and control of this ephemeral endocrine gland. Macrophages, lymphocytes, mast cells, monocytes, and eosinophils are found in CL of a variety of species (3). Their presence may indicate some role for the immune system in CL function.
