Melbourne, VIC, Australia – Walter and Eliza Hall Institute (WEHI) researchers have discovered how the growth of milk-producing mammary glands is triggered during puberty. Sleeping stem cells in the mammary gland are awoken by a protein dubbed FoxP1, according to the research that was published today in the journal Developmental Cell.
Stanford, CA, USA – New research from Stanford shows that skeletal stem cells in mice assume a more primitive developmental state in response to extensive regeneration needs and environmental cues.
Cambridge, MA, USA – Method boosts differentiation of stem cells into mature blood cell types, may help leukemia and lymphoma patients. Patients with blood cancers such as leukemia and lymphoma are often treated by irradiating their bone marrow to destroy the diseased cells. After the treatment, patients are vulnerable to infection and fatigue until new blood cells grow back.
Paris, France – While stem cells have the most therapeutic potential, the benefits of regenerative medicine may best be mobilised using extracellular vesicles (EVs), also known in the past as “cellular dust”. A team of researchers from CNRS, AP-HP, INSERM and Paris Descartes and Paris Diderot Universities have tested these vesicles for the first time in a porcine model for the treatment of post-operative digestive fistulas.
Boston, MA, USA – A team of Tufts University-led researchers has developed three-dimensional (3D) human tissue culture models for the central nervous system that mimic structural and functional features of the brain and demonstrate neural activity sustained over a period of many months. With the ability to populate a 3D matrix of silk protein and collagen with cells from patients with Alzheimer’s disease, Parkinson’s disease, and other conditions, the tissue models allow for the exploration of cell interactions, disease progression and response to treatment.
Urbana, IL, USA – Somatic stem cells are microscopic workhorses, constantly regenerating cells throughout the body: skin and the lining of the intestine, for example. And to University of Illinois neuroscientists, they represent untapped potential
Bristol, UK – The discovery, published in Nature Materials, is the first chemically programmed approach to producing an artificial tissue. The findings, which could have major health applications in the future, could see chemically programmed synthetic tissue being used to support failing living tissues and to cure specific diseases.
Atlanta, GA, USA – Using a combination of computational modeling and experimental techniques, a research team has developed new information about how intercellular communication affects the differentiation of an embryonic stem cell colony over time.
Cambridge, MA, USA – Researchers at the Chinese Academy of Sciences were able to produce healthy mice with two mothers that went on to have normal offspring of their own. Mice from two dads were also born but only survived for a couple of days.
Baltimore, MD, USA – Biologists at Johns Hopkins University grew human retinas from scratch to determine how cells that allow people to see in color are made. The work, published in the journal Science, lays the foundation to develop therapies for eye diseases such as color blindness and macular degeneration. It also establishes lab-created "organoids" as a model to study human development on a cellular level.
