by immunizing mice with endometrial cells from pregnant women , we obtained two hybridoma clones , 9d3 ( igg1 ) and 9e3 ( igg3 ) , secreting monoclonal antibodies ( moabs ) that selectively stained endometrial stromal cells having prolactin in their cytoplasm , but did not stain glandular epithelium nor small lymphoid cells .
