The placenta: a multifaceted, transient organ. [PDF]

open access: yes, 2015
The placenta is arguably the most important organ of the body, but paradoxically the most poorly understood. During its transient existence, it performs actions that are later taken on by diverse separate organs, including the lungs, liver, gut, kidneys ...

Non-canonical dorsoventral patterning in the moth midge Clogmia albipunctata [PDF]

open access: yes, 2017
This is the final version of the article. Available from BioMed Central via the DOI in this record.Background Bone morphogenetic proteins (BMPs) are of central importance for dorsal–ventral (DV) axis specification.

Vital dye labelling demonstrates a sacral neural crest contribution to the enteric nervous system of chick and mouse embryos [PDF]

open access: yes, 1991
We have used the vital dye, DiI, to analyze the contribution of sacral neural crest cells to the enteric nervous system in chick and mouse embryos. In order to label premigratory sacral neural crest cells selectively, DiI was injected into the lumen of ...

Genes for extracellular matrix-degrading metalloproteinases and their inhibitor, TIMP, are expressed during early mammalian development [PDF]

open access: yes, 1989
Extracellular matrix (ECM) remodeling accompanies cell migration, cell-cell interactions, embryo expansion, uterine implantation, and tissue invasion during mammalian embryogenesis.

Prospects for transgenesis in the chick [PDF]

open access: yes, 2004
Research to develop a useful method for genetic modification of the chick has been on-going since the first demonstrations in the mouse in the 1980s that genetic modification is an invaluable tool for the study of gene function. Manipulation of the chick

Embryonic stem cell differentiation and the analysis of mammalian development [PDF]

open access: yes, 2002
© UBC PressMolecular and cellular analysis of early mammalian development is compromised by the experimental inaccessibility of the embryo. Pluripotent embryonic stem (ES) cells are derived from and retain many properties of the pluripotent founder ...

Modeling mammalian gastrulation with embryonic stem cells

open access: yes, 2017
Understanding cell fate patterning and morphogenesis in the mammalian embryo remains a formidable challenge. Recently, in vivo models based on embryonic stem cells (ESCs) have emerged as complementary methods to quantitatively dissect the physical and ...

Heterogeneous X inactivation in trophoblastic cells of human full-term female placentas [PDF]

open access: yes, 1999
In female mammalian cells, one of the two X chromosomes is inactivated to compensate for gene-dose effects, which would be otherwise doubled compared with that in male cells.

Current status of in vitro differentiation of stem cells into gametes [PDF]

open access: yes, 2015
From an evolutionary point of view, the gametes are the cells in the body that matter the most as they are the ones who transmit their genes to the next generation ensuring continuation of the species. Being able to generate mature oocytes in vitro is of
