Notch1 mediates uterine stromal differentiation and is critical for complete decidualization in the mouse

Uterine receptivity implies a dialogue between the hormonally primed maternal endometrium and the free-floating blastocyst. Endometrial stromal cells proliferate, avert apoptosis, and undergo decidualization in preparation for implantation; however, the mo ...

Quantitative morphometry analysis of the fetal brain using clinical MR imaging

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer, Gabriele Vincenzo Bonanno

In vivo fetal magnetic resonance imaging provides a unique approach for the study of early human brain development [1]. In utero cerebral morphometry could potentially be used as a marker of the cerebral maturation and help to distinguish between normal an ...

HRG inhibits tumor growth and metastasis by inducing macrophage polarization and vessel normalization through downregulation of PlGF

Michele De Palma, Mario Leonardo Squadrito, Damya Laoui

Polarization of tumor-associated macrophages (TAMs) to a proangiogenic/immune-suppressive (M2-like) phenotype and abnormal, hypoperfused vessels are hallmarks of malignancy, but their molecular basis and interrelationship remains enigmatic. We report that ...

A post-processing pipeline to reconstruct the developing fetal brain using low-resolution MRI

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer

Introduction. Development of the fetal brain surface with concomitant gyrification is one of the major maturational processes of the human brain. First delineated by postmortem studies or by ultrasound, MRI has recently become a powerful tool for studying ...

Central and Cortical Gray Mater Segmentation of Magnetic Resonance Images of the Fetal Brain

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer, Gabriele Vincenzo Bonanno, Anouk André

Motivation. The study of human brain development in its early stage is today possible thanks to in vivo fetal magnetic resonance imaging (MRI) techniques. A quantitative analysis of fetal cortical surface represents a new approach which can be used as a ma ...

Biomechanical forces promote embryonic haematopoiesis

Olaia Maria Naveiras Torres-Quiroga

Biomechanical forces are emerging as critical regulators of embryogenesis, particularly in the developing cardiovascular system. After initiation of the heartbeat in vertebrates, cells lining the ventral aspect of the dorsal aorta, the placental vessels, a ...

Placental rescue reveals a sole requirement for c-Myc in embryonic erythroblast survival and hematopoietic stem cell function

Armin Ehninger

The c-Myc protein has been implicated in playing a pivotal role in regulating the expression of a large number of genes involved in many aspects of cellular function. Consistent with this view, embryos lacking the c-myc gene exhibit severe developmental de ...

Distinct requirements for Gab1 in Met and EGF receptor signaling in vivo

Gab1 is a multiadaptor protein that has been shown to be required for multiple processes in embryonic development and oncogenic transformation. Gab1 functions by amplifying signal transduction downstream of various receptor tyrosine kinases through recruit ...

Differentiation of Trophoblast Giant Cells and Their Metabolic Functions Are Dependent on Peroxisome Proliferator-Activated Receptor /

Didier Trono, Walter Wahli

Mutation of the nuclear receptor peroxisome proliferator-activated receptor beta/delta (PPARbeta/delta) severely affects placenta development, leading to embryonic death at embryonic day 9.5 (E9.5) to E10.5 of most, but not all, PPARbeta/delta-null mutant ...

Alveolar and lactogenic differentiation

Cathrin Brisken, Renuga Devi Rajaram

The mouse mammary gland is a complex tissue that proliferates and differentiates under the control of systemic hormones during puberty, pregnancy and lactation. Once a highly branched milk duct system has been established, during mid/late pregnancy, alveol ...
