hematopoietic system
• decrease in neutrophil numbers at 4 months post transplantation when bone marrow is transferred to lethally radiate syngenic recipient mice
• decrease is greater than in either single homozygote
• decrease in lymphocyte numbers at 4 months post transplantation when bone marrow is transferred to lethally radiate syngenic recipient mice
• decrease is greater than in either single homozygote
• total colony formation is increased in vitro and progenitors show an additive increase in CFU-G colony formation compared to either single homozygote

immune system
