Fatal hemorrhage in low-TF female mice

Breeding strategy	Level of TF expression		Fatal mid-gestational hemorrhage (E12–E16)	Fatal post-partum hemorrhage	Placental blood pools
Breeding strategy	Mother	Embryo	Fatal mid-gestational hemorrhage (E12–E16)	Fatal post-partum hemorrhage	Placental blood pools
♂ −/−, h⁺ × ♀ −/−, h⁺	Low	Low	17/41 (42%)	4/22 (18%)	Yes
♂ +/+ × ♀ −/−, h⁺	Low	Normal (+/−)	0/43	6/43 (14%)	No
♂ −/−, h⁺ × ♀ +/−, h⁺	Normal (+/−)	Normal (+/−)	0/273	0/273	No
	Normal (+/−)	Low			Yes

The breedings in the first row employed 6 male and 25 female mice. The breedings in the second row employed 5 male and 10 female mice. h⁺ represents h^+/− or h^+/+.
