LOADING: Immuno-florescent confocal image of a 4.5 day old mouse embryo with cell surface markers for each of the three cell fate lineages

Immuno-florescent confocal image of a 4.5 day old mouse embryo with cell surface markers for each of the three cell fate lineages (A, epiblast; blue, Pecam1; trophoblast, red; Cdcp1, primitive endoderm; green, Pdgfrα). These same markers are used to separate and isolate the different cell types from embryos using flow cytometry (B colours correspond to markers in A). The isolation of single cells enables the monitoring of cell fate development and population dynamics over time.

LOADING: A three dimensional plot of the top three principal components that separate different molecular classes of preeclampsia.

A three dimensional plot of the top three principal components that separate different molecular classes of preeclampsia. This analysis is the first to show that there are distinct molecular expression profiles among patients with clinically similar pathology. These results imply that the treatment of preeclampsia will require the development of therapies tailored to different molecular causes. This is analogous to the treatment of other multi-factorial diseases, such as cancer.

Gata3 regulates trophoblast development downstream of Tead4 and in parallel to Cdx2.

Ralston A, Cox BJ, Nishioka N, Sasaki H, Chea E, Rugg-Gunn P, Guo G, Robson P, Draper JS, Rossant J.

Development. 2010 Feb;137(3):395-403.

PubMed PMID: 20081188

LOADING: Role of the transcription factor Gata3 in trophoblast development.

The role of the transcription factor Gata3 in trophoblast development. Increased expression of Gata3 causes trophoblast stem cells (A) to differentiated in to trophoblast giant cells (B). This is confirmed by the loss of expression of Cdx2©, a trophoblast stem cell marker gene, and an increase in expression of Prl2c2©, a marker of differentiated trophoblast cells. Gata3 with inducible activity was expressed in trophoblast cells and induced with tamoxifen.

The study identifies Gata3 as having a dual role in trophoblast stem cell maintenance and differentiation, as well it identified Gata3 as functioning in parallel to the other known regulator of trophoblast development, Cdx2.

Comparative systems biology of human and mouse as a tool to guide the modeling of human placental pathology.

LOADING: Heat map of the integrated protein and mRNA expression profiles of human and mouse placentas.

Heat map of the integrated protein and mRNA expression profiles of human and mouse placentas. The proteins are separated into different subcellular fractions (top labels: cyto, cytoplasm; Mito, mitochondria; Memb, membrane; Nucl, nucleus), replicate DNA microarrays were used to assess mRNA expression. This analysis is limited to the ~11,000 1:1 orthologs between the two species.

The findings of this analysis and others in the study show that while human and mouse have many genes expressed in common there is significant unique gene expression. This suggests that there are limits to the ability of mice to model human pathologies.
