the timing , cell-size shifts and progressive amplification of the waves of regeneration accord with a dynamic model in which the tdt+14.8- , tdt+14.8+ and tdt-14.8+ cells form three successive stages in b-cell differentiation before the expression of mu chains , presumptively including the stage of mu chain gene rearrangement .
