Start-up company, Renovate Bioscience Inc., wins Invention of the Year and Inventor Pitch Award for this work at UMD

College Park, MD, USA – In a new paper published in Stem Cell Reports, Bhanu Telugu and co-inventor Chi-Hun Park of the University of Maryland (UMD) Department of Animal and Avian Sciences show for the first time that newly established stem cells from pigs, when injected into embryos, contributed to the development of only the organ of interest (the embryonic gut and liver), laying the groundwork for stem cell therapeutics and organ transplantation.

Oh So Simple: Eight Genes Enough to Convert Mouse Stem Cells into Oocyte-Like Cells

Surprisingly simple method could provide a new tool for producing specialized cytoplasm for reproductive medicine.

Fukuoka, Japan – In a new study published in the journal Nature, researchers in Japan report that activating just eight genes for producing gene-controlling proteins is enough to convert mouse stem cells directly into oocyte-like cells that mature and can even be fertilized like egg cells.

The Bull's Eye: New Modified Stem Cells Can Deliver Drugs Specifically to Tumor Cells

Scientists modified "mesenchymal stem cells" to carry anti-cancer drugs and deliver them to target cancers

Tokyo, Japan – Targeting drugs to cancer tissues is a major challenge in cancer treatment. Mesenchymal stem cells (MSCs) are known for their ability to find and target tumor cells in the body, but using MSCs for drug delivery has been tricky, because upon loading with drugs, MSCs lose their viability and migratory ability. Now, researchers from Tokyo University of Science have successfully modified MSCs to deliver large quantities of anti-cancer drugs in a targeted manner to developing cancer cells.

Research Dispels Fears Human Stem Cells Contain Cancer-Causing Mutations

Stembook: Research Dispels Fears Human Stem Cells Contain Cancer-Causing Mutations
Pioneering new research has made a pivotal breakthrough that dispel concerns that human stem cells could contain cancer-causing mutations.

Exeter, UK – A team of scientists from the University of Exeter’s flagship Living Systems Institute has shown that stem cells contain no cancer mutations when they are grown in their most primitive or naïve state.

Customized Programming of Human Stem Cells

Researchers harness 1732 transcription factors to obtain 290 new differentiation recipes

Bonn, Germany – Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues for drug testing and cell replacement therapies. However, the "recipes" for this conversion are often complicated and difficult to implement. Researchers at the Center for Regenerative Therapies Dresden (CRTD) at TU Dresden, Harvard University (USA) and the University of Bonn have found a way to systematically extract hundreds of different cells quickly and easily from iPS using transcription factors, including neurons, connective tissue and blood vessel cells. Researchers can use this transcription factor source through the non-profit organization Addgene. The results have now been published in the journal Nature Biotechnology
