MIT Develops New Stem Cell Isolation Technique.

Researchers have discovered a method of purifying mesenchymal stem cells from the other cells within the bone marrow.

In a new study, researchers from the Singapore-MIT Alliance in Research and Technology have identified three physical characteristics of mesenchymal stem cells [MSCs] that can distinguish them from other bone marrow-derived cell types. By isolating cells in the bone marrow based on size, stiffness, and fluctuations in the nuclear membrane, scientists can rapidly generate and purify the stem cells needed to treat patients.    Continue reading

Stem Cells With a Heart of Gold.

Scientists use gold nanoparticles to improve stem cell transplants for heart disease patients.

A team of bioengineers from Tel Aviv University is currently developing a scaffold to help regenerate heart muscle through the use of autologous stem cells.  The scientists, led by Dr. Tal Dvir, aim to replace damaged cardiac tissue in heart attack patients by creating a scaffold out of collagen and gold nanoparticles, and then infusing it with the patient’s own stem cells to stimulate the rejuvenation of cardiomyocytes.

Stem Cells Repair Damage via “First Aid Kits”

Scientists found that neural stem cells deliver restorative materials to other cells through vesicle transport.

In a recently published study, a team of researchers from the University of Cambridge has shown that neural stem cells are able to communicate and alleviate damage in other cells by transferring vesicles filled with molecules that enable the cells to repair themselves.  The cellular “first aid kits” contain proteins and nucleic acids that stimulate gene activation and signaling pathways to help the injured target cells survive.

Stem Cell Awareness Day 2014

The California Institute of Regenerative Medicine has coordinated Stem Cell Awareness day to highlight all of the progress that stem cells already made for patients around the world.

Today, stem cells are rightfully perceived as the future of regenerative medicine, set to bring the marvels of science fiction into reality.  But in looking ahead at all of the promise that stem cells hold for the future, it becomes easy to miss the scientific advances made to date for the millions of people around the world suffering from disease, trauma, and injury.  Thus, today marks Stem Cell Awareness Day: a global celebration of stem cell research coordinated to highlight the treatments and therapies currently in development to create personalized regenerative therapies for patients.
