The Formation and Selection of Cells Expressing PreB Cell Receptors and B Cell Receptorsbsequent stages of B cell development, all express an H chain in their cytoplasm (Rolink et al. 1994). One fifth of all large preB-II cells express the μH chains as complexes with surrogate L chains as so-called preB cell receptors on their surface (Winkler et al. 1995). In these cells the L chain l
