partial absorption of oligospecific reagents by the particulate membrane fraction prepared from isolated interstitial cells grown in culture ( the harvested cell population contained about 80 % leydig cells ) suggests that membranes of leydig cells carry antigenic specificities h-2k ( 11,25 ) and h-2d ( 4 ) but not antigens controlled by the i region .
