DN3 thymocyte
DN4 thymocyte
Note that this type of thymocyte has passed the beta-selection checkpoint and is rapidly proliferating and beginning to rearrange the T cell receptor alpha chain. There is growing evidence that molecular markers characterizing double negative thymocytes are different across species, especially in mouse versus human thymus. If in doubt, please consider using CL:0002489 'double negative thymocyte'.
