Placental exchange characteristics in young versus aged dams.
| Female | Male | |||
|---|---|---|---|---|
| Young | Aged | Young | Aged | |
| Barrier thickness (µm) | ||||
| 3.48 ± 0.21 | 3.17 ± 0.40 | 3.09 ± 0.14 | 3.82 ± 0.35 | |
| Surface area (cm2) | ||||
| MBS | 4.1 ± 0.71 | 3.38 ± 0.51 | 3.24 ± 0.34 | 4.06 ± 0.90 |
| FC | 2.21 ± 0.26 | 3.34 ± 0.62 | 2.10 ± 0.18 | 2.31 ± 0.55 |
| TDC (mm2/min/kPa) | ||||
| 0.00118 ± 0.00021 | 0.00134 ± 0.00025 | 0.00115 ± 0.00013 | 0.00119 ± 0.00035 | |
Data are from 4 placentas each from a different litter per group and are presented as mean ± SEM. No significance was detected between young and aged dams by unpaired t-test. TDC: total diffusing capacity.
