  "summary": "Hematopoiesis sustains lifelong blood production and immunity and is strongly influenced by biological sex. Males and females differ in their hematopoietic composition and susceptibility to infection and hematologic disease. Because current models cannot readily disentangle the independent contributions of sex chromosomes versus hormones, the mechanisms underlying sexual dimorphism remain poorly…",
