experiments utilizing an lps preparation to which the c3h/hej is totally unresponsive ( negative lps ) revealed , first , that either spleen cells , or partially purified t cells and/or macrophages obtained from c3h/st , could not restore the ability of c3h/hej spleen cells to respond to lps , indicating that the c3h/hej is not deficient in an lps-specific helper cell population which may be required for mitogenesis .
