Study shows functional effects of human stem cell delivery to heart muscle after heart attack


Researchers delivered human stem cells seeded in biological sutures to the damaged heart muscles of rats following induced acute myocardial infarction and assessed the effects on cardiac function one week later.

Peptides vs. superbugs


Several peptides have an antibacterial effect - but they are broken down in the human body too quickly to exert this effect. Empa researchers have now succeeded in encasing peptides in a protective coat, which could prolong their life in the human body. This is an important breakthrough because peptides are considered to be a possible solution in the fight against antibiotic-resistant bacteria.

New library of human stem cells with the Brazilian genetic admixture


New human pluripotent stem cells lines are derived from individuals of the Brazilian population - with European, African and Native American genomic ancestry; they can be used for testing drug toxicity and for studying differential drug response

Nanofiber scaffolds show new behaviour of stem and cancer cells


A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.

Cell under observation: "The software lets us study the development on video"


What happens when stem cells differentiate? What molecular characteristics do they have? Questions that can now be easier answered with the help of a new open-source software. We spoke with Prof. Fabian Theis at the Helmholtz Center Munich, who participated in the software development.

Embryonic gene Nanog reverses aging in adult stem cells


The fountain of youth may reside in an embryonic stem cell gene named Nanog. In a series of experiments at the University at Buffalo, the gene kicked into action dormant cellular processes that are key to preventing weak bones, clogged arteries and other telltale signs of growing old.

Different specialties, one goal – treating children right


Children, especially newborns, are generally no longer simply considered to be small adults whose treatment just needs to be "reduced". This is why a pediatrician’s education includes several specialties because ultimately everything in terms of care comes together here.

Great leaps forward thanks to new methods


Self-healing powers like a superhero on the big screen? That’s the aim of regenerative medicine; at least in a very broad sense. This promising field of biomedicine is currently highly dynamic with innovative technologies and development. New methods are designed to help propel medicine into a whole new sphere.

Hospital crisis communication: A crisis knows no rules


Crises come in many shapes and sizes. Whether it’s poor hygiene, thefts or treatment errors – once the crisis has arrived, things need to move quickly. For hospitals in particular, the right crisis communication is key. Yet many medical facilities still neglect the fact that crisis communication starts before the actual crisis takes place.

Digital pathology: From microscope slide to virtual microscopy


The digitization of medicine moves on. Researchers, physicians and patients equally benefit from this development – thanks to improved diagnostics with highly sensitive devices, today findings can be comprehensively analyzed and treatment decisions made on a broadened basis. Digitization also offers the area of pathology interesting fields of application.

"Studies involving microgravity suggest stem cells will grow faster in space"


The International Space Station ISS is not only the largest artificial object in space. It is also a laboratory for physicists, chemists, biologists and physicians and orbits earth at 28.000 kilometers per hour at an altitude of 400 kilometers. Thanks to this location, the ISS could one day make an important contribution to regenerative medicine.
