Cellular "barcoding" in mice unravels the origins of blood

The origins of our blood may not be quite what we thought. Using cellular "barcoding" in mice, a groundbreaking study finds that blood cells originate not from one type of mother cell, but two, with potential implications for blood cancers, bone marrow transplant, and immunology. Fernando Camargo, PhD, of the Stem Cell Program at Boston Children's Hospital led the study, published in Nature on June 15.

RNA exosomes play a key role in B cell development, UTSW study suggests

New research from UT Southwestern suggests that RNA exosomes – the cellular machines that degrade old molecules of RNA – play a key role in the development of B cells, which are critical to the immune system's ability to protect against infection.

Study sheds new light on the role of transcription factors in bone marrow microenvironments

In your home, storing books on a bookshelf, tools in a tool box, and a broom in a broom cupboard makes it easy to access these items whenever you need them.

Sonic hedgehog plays key role in the repair strategy of large bone injuries

A USC Stem Cell study in NPJ Regenerative Medicine presents intriguing evidence that large bone injuries might trigger a repair strategy in adults that recapitulates elements of skeletal formation in utero. Key to this repair strategy is a gene with a fittingly heroic name: Sonic hedgehog.

Blood adenosine levels positively correlate to the white matter lesions in very low birth weight premature infants

Prematurity affects about 10% of pregnancies worldwide each year. In about 20% of very low birth weight (VLBW) premature infants, punctate white matter lesions (PWML) can be diagnosed at MRI at term equivalent age.

Saving lives with living cells: Beckman Coulter Life Sciences launches AQUIOS STEM System to provide a new solution for stem cell analysis

Creating the industry’s first stem cell analysis update in nearly 25 years, Beckman Coulter Life Sciences – a global leader in laboratory automation and innovation – launches an evolution of the gold standard in hematopoietic stem cell enumeration, the AQUIOS STEM System.

New therapeutic approach for cardiac repair after a heart attack

Following a heart attack, the human body is incapable of repairing lost tissue due to the heart's inability to generate new muscle.

Epigenetic abnormalities in hematopoietic cells during fetal development cause idiopathic autism

An international research group led by Professor Toru Takumi (Senior Visiting Scientist, RIKEN Center for Biosystems Dynamics Research) and Researcher Chia-wen Lin at Kobe University Graduate School of Medicine has shown that idiopathic autism is caused by epigenetic abnormalities in hematopoietic cells during fetal development, which results in immune dysregulation in the brain and gut.

Study illustrates how a protein complex controls genome organization to maintain lineage fidelity

Understanding the molecular mechanisms that specify and maintain the identities of more than 200 cell types of the human body is arguably one of the most fundamental problems in molecular and cellular biology, with critical implications for the treatment of human diseases. Central to the cell fate decision process are stem cells residing within each tissue of the body.

Penn scientists discover how one inflammatory disorder increases susceptibility to another

The immune system remembers. Often this memory, primed by past encounters with threats like bacteria or viruses, is an asset. But when that memory is sparked by internal drivers, like chronic inflammation, it can prove detrimental, perpetuating a misguided immune response.

Researchers reveal possible way to treat newborns with rare genetic lung condition

When babies are born with alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV), their skin starts to turn blue from the under-oxygenated blood in their systems.

Researchers investigate Zika virus and Dengue virus co-immunity

In a new study, researchers successfully created new strains of the Zika virus and proved that the process of passaging through mice resulted in significantly increased virulence.

Scientists precisely define the ‘identity card’ of pancreatic endocrine cells

The pancreas is a key metabolic regulator. When pancreatic beta cells cease producing enough insulin, blood sugar levels rise dangerously — a phenomenon known as hyperglycemia — thus triggering diabetes.

Researchers identify certain gene regulation signatures in CAR T-resistant leukemia patients

Acute lymphoblastic leukemia (ALL) cells from patients whose cancers did not respond to CD19-targeted CAR T therapy had gene regulation signatures that could potentially facilitate treatment resistance, according to results presented at the AACR Annual Meeting 2022, held April 8-13.
