Neurexophilin1 suppresses the proliferation of hematopoietic progenitor cells
Neurexophilin Dystroglycan Hematopoiesis Hematopoietic niche
2015/5/21
Neurexin I alpha (NRXN1α) and Dystroglycan (DAG1) are membrane receptors which serve as mutual ligands in the neuronal system. Neurexophilins (NXPHs) bind NRXN1α. Both NRXN1α and DAG1 were expressed i...
Regulation of mammary stem/progenitor cells by p53 and parity
Biological sciences Progenitor cells Adult stem cells Breast neoplasms Li-fraumeni syndrome Mammary gland Notch proteins Tumor suppressor protein p53
2014/12/10
Breast cancer is the most common tumor among women with inherited mutations in the p53 gene (Li-Fraumeni syndrome). The tumors represent the basal-like subtype which has been suggested to originate fr...
The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
Prostaglandin E₂ promotes recovery of hematopoietic stem and progenitor cells after radiation exposure
hematopoiesis radiomitigation radiation
2015/5/21
The hematopoietic system is highly proliferative, making hematopoietic stem and progenitor cells (HSPC) sensitive to radiation damage. Total body irradiation and chemotherapy, as well as the risk of r...
Defining the mechanism of prostaglandin E₂-enhanced hematopoietic stem and progenitor cell homing
Prostaglandin Homing HIF1-alpha
2015/5/21
Hematopoietic stem cell (HSC) transplantation is a lifesaving therapy for a number of hematological disorders. However, to be effective, transplanted HSCs must efficiently “home” to supportive niches ...
Pasadena, CA—Wolf-Rayet stars are very large and very hot. Astronomers have long wondered whether Wolf-Rayet stars are the progenitors of certain types of supernovae. New work from the Palomar Transie...
Transcriptional Regulation of Retinal Progenitor Cells Derived from Human Induced Pluripotent Stem Cells.
Stem Cell Human iPS Differentiation Development Retina
2015/5/22
In order to develop effective cures for diseases and decipher disease pathology, the need exists to cultivate a better understanding of human development. Existing studies employ the use of animal mod...
The Progenitor Mass of SN 2011dh from Stellar Populations Analysis
Progenitor Mass Stellar Populations Analysis
2011/10/18
Using Hubble Space Telescope (HST) photometry, we characterize the age of the stellar association in the vicinity of supernova (SN) 2011dh and use it to infer the zero-age main sequence mass (M_{ZAMS}...
Another Look at the EBS: A Stellar Debris Stream and a Possible Progenitor
Another Look Stellar Debris Stream Possible Progenitor
2011/10/19
Using the Sloan Digital Sky Survey Data Release 7, we reexamine the Eastern Banded Structure (EBS), a stellar debris stream first discovered in Data Release 5 and more recently detected in velocity sp...
Panchromatic Observations of SN 2011dh Point to a Compact Progenitor Star
Panchromatic Observations Compact Progenitor Star
2011/9/30
We report the discovery and detailed monitoring of X-ray emission associated with the Type IIb SN 2011dh using data from the Swift and Chandra satellites, placing it among the best studied X-ray super...
Effects of Altering Cell Proliferation on Hematopoietic Stem and Progenitor Cell Function
hematopoietic progenitor cell cell cycle
2015/5/21
Cell cycle checkpoints guarantee movement through the cell cycle in an appropriate manner. The spindle assembly checkpoint (SAC) ensures the proper segregation of chromosomes into daughter cells durin...
Caltech Core-Collapse Project (CCCP) observations of type IIn supernovae: typical properties and implications for their progenitor stars
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/31
Type IIn Supernovae (SNe IIn) are rare events, constituting only a few percent of all core-collapse SNe, and the current sample of well observed SNe IIn is small. Here, we study the four SNe IIn obser...
Eicosanoid Regulation of Hematopoietic Stem and Progenitor Cell Function
AMD3100 G-CSF NSAID EP receptor Meloxicam
2015/5/21
dult hematopoietic stem cells (HSC) are routinely used to reconstitute hematopoiesis after myeloablation; however, transplantation efficacy and multilineage reconstitution can be limited by inadequate...
