Exercise on Progenitor Cells in Healthy Subjects and Patients with Type 1 Diabetes
DIABETES BLOOD CIRCULATION ENDOTHELIUM
2017/4/13
Purpose: To evaluate the acute effect of aerobic exercise (AE) and resistance exercise (RE) on the release of endothelial progenitor cell (EPCs, CD34+/KDR+/CD45dim) and vascular function in type 1 dia...
IMPACT OF ALCAM (CD166) ON HOMING OF HEMATOPOIETIC STEM AND PROGENITOR CELLS
endosteal bone marrow vascular bone marrow flow cytometry
2015/5/25
The potential of hematopoietic stem cells (HSC) to home and to anchor within the bone marrow (BM) microenvironment controls the ability of transplanted HSCs to establish normal hematopoiesis. Activate...
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...
Resistance Exercise Increases Endothelial Progenitor Cells and Angiogenic Factors
Vascularendothelialgrowthfactor matrixmetalloproteinases muscleendurance muscleischemia
2017/5/17
Introduction: Bone marrow-derived endothelial progenitor cells (EPC) are involved in vascular growth and repair. They increase in the circulation after a single bout of aerobic exercise, potentially r...
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...
