Researchers gain new insight into regulation of adult nerve cell generation in the hypothalamus

Researchers from the University of Utah have gained new insight into the regulation of adult nerve cell generation in the hypothalamus, the part of the brain that regulates many aspects of behavior, mood, and metabolism.

Researchers discover small DNA sequence that drives GATA2 protein

The protein GATA2 is known as a "master regulator" of blood cell development. When a mutation occurs in the gene that makes GATA2, serious blood diseases such as acute myeloid leukemia can result.

TSC and PTEN genes important in controlling blood precursor cells in Drosophila

UCLA stem cell scientists have shown that two common tumor suppressor genes, TSC and PTEN, are vital to regulating the stem cell-like precursor cells that create the blood supply in Drosophila, the common fruit fly.

Chemical properties of green tea benefit memory and spatial learning

It has long been believed that drinking green tea is good for the memory. Now researchers have discovered how the chemical properties of China's favorite drink affect the generation of brain cells, providing benefits for memory and spatial learning. The research is published in Molecular Nutrition & Food Research.

Missing link between bone marrow stem cells and human immune system

UCLA researchers have discovered a type of cell that is the "missing link" between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.

SSEA4+ marker helps identify and isolate precursors of insulin-producing pancreatic cells

For the millions of people worldwide with type 1 diabetes who cannot produce sufficient insulin, the potential to transplant insulin-producing cells could offer hope for a long-term cure. The discovery of a marker to help identify and isolate stem cells that can develop into insulin-producing cells in the pancreas would be a critical step forward and is described in an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc.

Arteriocyte receives NIH grant for use of NANEX platform in bone marrow transplant

Arteriocyte, a leading clinical stage biotechnology company developing cellular based therapies to treat human diseases, announced today the successful award of another grant by the National Institute of Health for the use of the NANEX platform in Hematopoietic Reconstitution Using Ex Vivo Expanded Umbilical Cord Blood CD34+ Stem Cells.

External stimulation impacts postnatal development of brain's white matter

A team at Children's National Medical Center has found that external stimulation has an impact on the postnatal development of a specific region of the brain. Published in Nature Neuroscience, the study used sensory deprivation to look at the growth and collection of NG2-expressing oligodendrocyte progenitor cells (NG2 cells) in the sensory cortex of the brain.

Researchers discover surprising and unexpected plasticity in the embryonic endothelium

UCLA stem cell researchers have found for the first time a surprising and unexpected plasticity in the embryonic endothelium, the place where blood stem cells are made in early development.

Antibody detects progenitor cells in cancers and cirrhosis of liver

The study, published in the journal Stem Cell, adds to our understanding of the role of stem and next stage progenitor cells in tissue regeneration and in the diagnosis and treatment of cancer.

Placenta-derived endothelial colony-forming cells are more vasculogenic: Study

A study comparing whether endothelial colony-forming cells (ECFCs) derived from human placenta or those derived from human umbilical cord blood are more proliferative and better for forming new blood vessels has found that ECFCs derived from human placenta are more vasculogenic.

Thrombopoietin mimetic offers aplastic anemia hope

Eltrombopag significantly improves blood counts in some patients with refractory severe aplastic anemia, suggests research published in The New England Journal of Medicine.

Disabling Nf1 gene makes stem cells from the third ventricle proliferate rapidly

Scientists showed in mice that disabling a gene linked to a common pediatric tumor disorder, neurofibromatosis type 1 (NF1), made stem cells from one part of the brain proliferate rapidly. But the same genetic deficit had no effect on stem cells from another brain region.

New insights into role and importance of exosomes and their targeted gene transcripts

In the July 6 issue of Cell Stem Cell, researchers at the University of California, San Diego School of Medicine describe how human epidermal progenitor cells and stem cells control transcription factors to avoid premature differentiation, preserving their ability to produce new skin cells throughout life.

Abnormal bone marrow stem cells drive development of myelodysplastic syndromes

Researchers at Albert Einstein College of Medicine of Yeshiva University have found that abnormal bone marrow stem cells drive the development of myelodysplastic syndromes (MDS), serious blood diseases that are common among the elderly and that can progress to acute leukemia. The findings could lead to targeted therapies against MDS and prevent MDS-related cancers. The study is published today in the online edition of the journal Blood.

Scientists transplant stem cells from patients with limb-girdle muscular dystrophy into mice

Stem cells from patients with a rare form of muscular dystrophy have been successfully transplanted into mice affected by the same form of dystrophy, according to a new study published today in Science Translational Medicine.

Magnet guides iron-loaded cells to specific damaged sites in the heart

Optimal stem cell therapy delivery to damaged areas of the heart after myocardial infarction has been hampered by inefficient homing of cells to the damaged site. However, using rat models, researchers in France have used a magnet to guide cells loaded with iron oxide nanoparticles to key sites, enhancing the myocardial retention of intravascularly delivered endothelial progenitor cells.

Study reveals previously unknown function of Thbd-aPC pathway in radiation mitigation

New research in Nature Medicine shows that boosting a protein pathway in the body's blood making system protects mice from otherwise fatal radiation poisoning.
