Developmental Dynamics of the Definitive Mouse Placenta Assessed by Stereology1

Abstract

The mouse is an excellent model for studying the genetic basis of placental development, but analyses are restricted by the lack of quantitative data describing normal murine placental structure. This study establishes a technique for generating such data, applies stereological techniques on systematic uniform random sections of placentas between E12.5-E18.5 of gestation (E1.0 = day of the vaginal plug), and considers the results in the context of development of the labyrinth zone. Half of each placenta was wax embedded and exhaustively sectioned to determine absolute volumes of the labyrinth zone (Lz), junctional zone (Jz), and decidua using the Cavalieri principle. The other half was resin embedded and 1-microm sections were used to generate all volume, surface, and length densities within the Lz. Maximum placental volume is reached by E16.5, whereas the Lz volume fraction increases until E18.5 at the expense of the Jz and decidua. Within the Lz, the absolute volume and surface area of maternal blood spaces (MBS) expand rapidly between E14.5 and E16.5, with no increase thereafter. In contrast, fetal capillary development is linear and continues for longer than that of the MBS. The interhemal membrane separating maternal and fetal circulations undergoes thinning prior to expansion of maternal and fetal surface areas, achieving a harmonic mean thickness of 4.39 microm by E18.5. The specific diffusion capacity for oxygen of the interhemal membrane is maximal by E16.5, which may be necessary to support rapid fetal growth until the end of gestation.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Total fetal capillary surface area increases, favoring exchange, although mean capillary diameter is reduced.

    “Consequently, total fetal capillary surface area increases, favoring exchange, although mean diameter is reduced, as in the mouse (54,116).”

  • The mouse placenta undergoes rapid growth, with weight reaching a maximum around E16.5 and plateauing or declining thereafter.

    “The placenta undergoes rapid growth, with weight reaching a maximum around E16.5 and plateauing, or even declining, thereafter (116).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
