Biology Open, 2012 Summary The yolk syncytial layer (YSL) performs multiple critical roles during zebrafish development. However, little is known about the cellular and molecular mechanisms that underlie the formation of this important extraembryonic structure.

Differential elasticity in lineage segregation of embryonic stem cells [PDF]
arXiv, 2022 The question of what guides lineage segregation is central to development, where cellular differentiation leads to segregated cell populations destined for specialized functions. Here, using optical tweezers measurements of mouse embryonic stem cells (mESCs), we reveal a mechanical mechanism based on differential elasticity in the second lineage ...

Fluctuation spectra of free and supported membrane pairs [PDF]
European Physical Journal E 23, 103-116 (2007), 2006 Fluctuation spectra of fluid compound membrane systems are calculated. The systems addressed contain two (or more) almost parallel membranes that are connected by harmonic tethers or by a continuous, harmonic confining potential. Additionally, such a compound system can be attached to a supporting substrate.

Elastic moderation of intrinsically applied tension in lipid membranes [PDF]
Phys. Rev. E 83, 011913 (2011), 2010 Tension in lipid membranes is often controlled externally, by pulling on the boundary of the membrane or changing osmotic pressure across a curved membrane. But modifications of the tension can also be induced in an internal fashion, for instance as a byproduct of changing a membranes electric potential or, as observed experimentally, by activity of ...

Amnion formation in the mouse embryo: the single amniochorionic fold model [PDF]
, 2011 Background Despite the detailed knowledge obtained over the last decade on the molecular regulation of gastrulation in amniotes, the process of amnion development has been poorly described and illustrated in mice, and conflicting descriptions exist ...

Development of the Human Placenta and Fetal Heart: Synergic or Independent?
Frontiers in Physiology, 2018 The placenta is the largest fetal organ, and toward the end of pregnancy the umbilical circulation receives at least 40% of the biventricular cardiac output.
