Photo: Detail of breast epithelial cells [15/06/2015] About 70.000 women are diagnosed with breast cancer every year in Germany alone. Despite significant progress in the treatment of common types of breast cancer, some aggressive subtypes of the disease are poorly understood and remain incurable. A new experimental model opens new avenues for mammary gland biology and basic breast cancer research. Mini-breast grown in petri dishes - Read more

Focusing on the difficult case of restoring cartilage, which requires both flexibility and mechanical strength, the researchers investigated a new combination of 3-D printed microfiber scaffolding and hydrogels.Soft-tissue engineering for hard-working cartilage - Read more

How cancer tricks the lymphatic system into spreading tumors

Photo: A trojan horse [13/05/2015] Swollen lymph nodes are often the earliest sign of metastatic spread of cancer cells. Now cancer researchers and immunologists at Sweden's Karolinska Institutet have discovered how cancer cells can infiltrate the lymphatic system by 'disguising' themselves as immune cells (white blood cells).How cancer tricks the lymphatic system into spreading tumors - Read more

New material for creating artificial blood vessels

Graphic: Blood vessel with erythrocytes [29/04/2015] Blocked blood vessels can quickly become dangerous. It is often necessary to replace a blood vessel – either by another vessel taken from the body or even by artificial vascular prostheses. Together, Vienna University of Technology and Vienna Medical University have developed artificial blood vessels made from a special elastomer material, which has excellent mechanical properties.New material for creating artificial blood vessels - Read more

Breast tumor: Metastasis risk linked by molecule's movement

Photo: Microscope image [22/04/2015] Researchers at the University of California, San Diego School of Medicine and Moores Cancer Center have discovered a molecular mechanism that connects breast tissue stiffness to tumor metastasis and poor prognosis. The study may inspire new approaches to predicting patient outcomes and halting tumor metastasis.Breast tumor: Metastasis risk linked by molecule's movement - Read more

Heart cells regenerated in mice

Photo: Heart cells [15/04/2015] As opposed to blood, hair or skin cells that can renew themselves throughout life, our heart cells cease to divide shortly after birth, and there is very little renewal in adulthood. New research provides insight into the question of why the mammalian heart fails to regenerate, on one hand, and demonstrated, in adult mice, the possibility of turning back this fate.Heart cells regenerated in mice - Read more

MIPT researchers grow cardiac tissue on 'spider silk' substrate

( Source: MEDICA.de )

Photo: green fluorescent heart tissue cells [13/04/2015] Genetically engineered fibers of the protein spidroin, which is the construction material for spider webs, has proven to be a perfect substrate for cultivating heart tissue cells, MIPT researchers found. They discuss their findings in an article that has recently come out in the journal PLOS ONE. MIPT researchers grow cardiac tissue on 'spider silk' substrate - Read more
