New solution for stem cell manufacturing
Researchers have developed a unique 3D printed system for harvesting stem cells from bioreactors, offering the potential for high quality, wide-scale production of stem cells in Australia at a lower cost.

Following a heart attack, the human body is incapable of repairing lost tissue due to the heart’s inability to generate new muscle. However, treatment with heart progenitor cells could result in the formation of functional heart cells at injured sites. This new therapeutic approach may be tested in clinical studies within the next two years.
In a study published in the Journal of the American Medical Association (JAMA), Johns Hopkins Medicine researchers show that although two doses of a vaccine against SARS-CoV-2 — the virus that causes COVID 19 — confers some protection for people who have received solid organ transplants, it’s still not enough to enable them to dispense with masks, physical distancing and other safety measures.
A long noncoding RNA whose function was previously unknown turns out to play a vital role in mobilizing the immune response following a bone marrow transplant or solid organ transplantation.
In all adult vertebrates, neural stem cells can be recruited to produce new neurons in the brain. However, little is known about these so-called “activation” processes.
Harvard University researchers have identified the biological mechanism of how chronic stress impairs hair follicle stem cells, confirming long-standing observations that stress might lead to hair loss.
Researchers at the University of Southampton have developed a new way of using nanomaterials to identify and enrich skeletal stem cells — a discovery which could eventually lead to new treatments for major bone fractures and the repair of lost or damaged bone.
A UCLA-led research team has identified a chemical cocktail that enables the production of large numbers of muscle stem cells, which can self-renew and give rise to all types of skeletal muscle cells.
Making gametes such as sperm and eggs from pluripotent stem cells, primitive cells that can make all the tissues, greatly contributes to efficient reproduction of livestock animals and future assisted reproductive medicine. Researchers pave the way to achieve this goal using a body of xenogenic animals.
The stem cells in our brain generate new neurons throughout life, for example in the hippocampus. This region of the brain plays a key role for a range of memory processes. With increasing age, and in patients suffering from Alzheimer’s disease, the hippocampus’ ability to create new neurons declines steadily — and with it, its memory functions.
