immune system
• minimal numbers of double positive thymocytes enter into the cell cycle during the double positive stage
• thymocytes fail to express an alphabeta TCR
• there is a partial block in development in the DN3 stage that is more severe in the double homozygote null mice than in the singly- homozygote null mice
• there is a partial block in development in the DN3 stage that leads to a higher percentage of these thymocytes
• double-positive thymocytes are almost absent from the thymus in 6 week old mice
• the double-positive thymocyte population is slightly larger by nine weeks of age

hematopoietic system
