Spectral Models for Early Time SN 2011fe Observations [PDF]

, 2015
We use observed UV through near IR spectra to examine whether SN 2011fe can be understood in the framework of Branch-normal SNe Ia and to examine its individual peculiarities.

Loss of Stat3 in Prx1+ Progenitors Impairs Molar Root Development

Advanced Biology, EarlyView.
Stat3 critically regulates mandibular first molar and alveolar bone morphogenesis. Conditional ablation of Stat3 disrupts the osteogenic capacity of Prx1+ mesenchymal progenitors, as evidenced across in vivo and in vitro models. Abstract Signal Transducer and Activator of Transcription 3 (Stat3) acts as a central transcriptional modulator coordinating ...

Mass-accreting white dwarfs and type Ia supernovae

, 2018
Type Ia supernovae (SNe Ia) play a prominent role in understanding the evolution of Universe. They are thought to be thermonuclear explosions of mass-accreting carbon-oxygen white dwarfs (CO WDs) in binaries, although the mass donors of the accreting WDs

Observational constraints on the progenitors of core-collapse supernovae : the case for missing high mass stars [PDF]

, 2015
Over the last 15 years, the supernova community has endeavoured to identify progenitor stars of core-collapse supernovae in high resolution archival images of their galaxies.This review compiles results (from 1999 - 2013) in a distance limited sample and

A Vascularized Microphysiological System Reproducing Endochondral Ossification in Vitro to Study Ewing Sarcoma Proliferation and Migration

Advanced Functional Materials, EarlyView.
A biofabricated 3D in vitro model recapitulating endochondral ossification (ECO) is described, mimicking the steps from condensation to chondrogenesis and hypertrophy, culminating with vascularization of the hypertrophic construct. As a model proof of concept application, Ewing Sarcoma cells are seeded in the model, showing modifications in their ...

Identification of mouse and human embryonic pancreatic cells with adult Procr+ progenitor transcriptomic and epigenomic characteristics

Frontiers in Endocrinology
BackgroundThe quest to find a progenitor cell in the adult pancreas has driven research in the field for decades. Many potential progenitor cell sources have been reported, but so far this is a matter of debate mainly due to reproducibility issues.
