Collection:

Collection ID:CO001071
Collection Summary:The placentas were collected immediately following cesarean delivery, and the tissue specimens were collected from the whole placenta at five time points postdelivery: (1) < 5 min (n = 6); (2) 15 min (n = 13); (3) 30 min (n = 13); (4) 1 h (n = 13); (5) 24 h (n = 13). The tissue specimens were immediately frozen in liquid nitrogen following collection. The whole placentas were kept at 4 °C between sampling time points. Tissue specimens were collected from two areas of the maternal (approximately 1 × 1 cm area; depth of 1 cm) and fetal surfaces (approximately 1 × 1 cm area; depth of 0.3 cm) of each placenta at each time point, resulting in 24 total specimens for the < 5 min time point and 52 total specimens for all other time points. Tissue specimens were immediately frozen in liquid nitrogen following collection and stored at −80 °C until metabolomic analysis
Sample Type:Placenta
Collection Method:Tissue specimens were collected from two areas of the maternal (approximately 1 × 1 cm area; depth of 1 cm) and fetal surfaces (approximately 1 × 1 cm area; depth of 0.3 cm) of each placenta at each time point by cutting with sterile scalpel and forceps on a sterile surface. The tissue specimens were immediately frozen in liquid nitrogen following collection.
Collection Frequency:Tissue specimens were collected from the whole placenta at five time points postdelivery: (1) < 5 min (n = 6); (2) 15 min (n = 13); (3) 30 min (n = 13); (4) 1 h (n = 13); (5) 24 h (n = 13)
