New In Vivo Priming Strategy To Train Stem Cells Can Enhance Cardiac Repair Effectiveness

STEMBOOK: New In Vivo Priming Strategy To Train Stem Cells Can Enhance Cardiac Repair Effectiveness

Kowloon Tong, Hong Kong – Human stem cells have been regarded as one of the promising cell sources for cardiac regeneration therapy. But their clinical use is hampered due to the poor performance after transplantation into failing hearts. Recently a stem cell biologist from City University of Hong Kong (CityU), together with his collaborators, has developed a novel strategy, called in vivo priming, to "train" the stem cells to stay strong after implantation to the damaged heart via the 3D-printed bandage-like patch. The positive results of the study show that an in vivo priming strategy can be an effective means to enhance cardiac repair.

Stem Cells and Nerves Interact in Tissue Regeneration and Cancer Progression

Zurich, Switzerland – Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumor innervation could thus lead to new cancer therapies. The research was published in FASEB

New UCI-Led Study Reveals How Skin Cells Prepare To Heal Wounds

STEMBOOK: New UCI-Led Study Reveals How Skin Cells Prepare To Heal Wounds
Discovery could lead to better understanding of poor wound healing in diabetic patients.

Irvine, CA, USA – A team of University of California, Irvine researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds. Results from the study provide a blueprint for future investigation into pathological conditions associated with poor wound healing, such as in diabetic patients.

New Technique ‘Prints’ Cells to Create Diverse Biological Environments

Berkely, CA, USA – Like humans, cells are easily influenced by peer pressure. Take a neural stem cell in the brain: Whether this cell remains a stem cell or differentiates into a fully formed brain cell is ultimately determined by a complex set of molecular messages the cell receives from countless neighbors. Understanding these messages is key for scientists hoping to harness these stem cells to treat neurological conditions like Alzheimer’s or Parkinson’s.

A Newly Discovered Memory In Our Bones: Blood Stem Cells Boost Immunity By Keeping A Record Of Previous Infections

Stembook: A Newly Discovered Memory In Our Bones: Blood Stem Cells Boost Immunity By Keeping A Record Of Previous Infections

Dresden, Germany – A Franco-German research team led by Prof. Michael Sieweke, from the Center for Regenerative Therapies TU Dresden (CRTD) and the Center of Immunology of Marseille Luminy (CNRS, INSERM, Aix-Marseille University), today uncovered a surprising property of blood stem cells: not only do they ensure the continuous renewal of blood cells and contribute to the immune response triggered by an infection, but they can also remember previous infectious encounters to drive a more rapid and more efficient immune response in the future. These findings should have a significant impact on future vaccination strategies and pave the way for new treatments of an underperforming or over-reacting immune system. The results of this research are published in Cell Stem Cell on March 12, 2020.

‘Primitive’ Stem Cells Shown to Regenerate Blood Vessels in The Eye

Stembook: ‘Primitive’ Stem Cells Shown to Regenerate Blood Vessels in The Eye

Baltimore, MD, USA – Johns Hopkins Medicine scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes. The findings from this experimental study, they say, advance regenerative medicine techniques aimed at reversing the course of diabetic retinopathy and other blinding eye diseases.

University of Minnesota First to Prove New Method to Grow Human Blood Vessels

Stembook: University of Minnesota First to Prove New Method to Grow Human Blood Vessels

Minneapolis, MN, USA – A team of researchers at the University of Minnesota Medical School recently proved the ability to grow human-derived blood vessels in a pig—a novel approach that has the potential for providing unlimited human vessels for transplant purposes. Because these vessels were made with patient-derived skin cells, they are less likely to be rejected by the recipient, helping patients potentially avoid the need for life-long, anti-rejection drugs.
