Citrate-Based Biomaterial Fuels Bone Healing With Less Rejection

pennstate news

University Park, PA, USA – A material based on a natural product of bones and citrus fruit, called citrate, provides the extra energy that stem cells need to form new bone tissue, according to a team of Penn State bioengineers. Their new understanding of the mechanism that allows citrate to aid in bone regeneration will help the researchers develop slow-release, biodegradable, citrate-releasing scaffolds to act as bone-growth templates to speed up healing in the body.

Proposed Cancer Treatment May Boost Lung Cancer Stem Cells, Study Warns

boston news

Boston, MA, USA – Epigenetic therapies – targeting enzymes that alter what genes are turned on or off in a cell – are of growing interest in oncology as a way to make cancers less aggressive or less malignant. But now, at least one epigenetic therapy that had looked promising for lung cancer appears to boost the cancer stem cells that are believed to drive tumors. A study published in Nature Communications also identifies a strategy that reduces these stem cells, curbing lung cancer in mice.

Human Brain Cell Transplant Offers Insights into Neurological Conditions

Scientists enables connectivity of human brain cells connect to be seen

London, UK – In a new study led by Imperial College London in collaboration with a group from the University of Cambridge, researchers transplanted human brain cells into a mouse brain, and for the first time watched how they grew and connected to each other. This allowed the team to study the way human brain cells interact in a more natural environment than previously possible.

Killing Cancer with Stem Cells

Kyoto, Japan – A key determinant of successful immunotherapies is immune cells targeting the pathology with high specificity. CiRA scientists are using iPS cell technology to make a large batch of immune cells for immunotherapies. However, retaining the antigen specificity remains a challenge. A new study by the CiRA Associate Professor Shin Kaneko laboratory reports a method that solves this problem.

Brain and Muscle Cells Found Lurking in Kidney Organoids Grown in Lab

Researchers find simple way to prevent wayward cells from developing

St. Louis, MO, USA – Scientists hoping to develop better treatments for kidney disease have turned their attention to growing clusters of kidney cells in the lab. One day, so-called organoids – grown from human stem cells – may help repair damaged kidneys in people or be used to test drugs developed to fight kidney disease.

New ‘SLICE’ Tool Can Massively Expand Immune System’s Cancer-Fighting Repertoire

San Francisco, CA, USA – Immunotherapy can cure some cancers that until fairly recently were considered fatal. In addition to developing drugs that boost the immune system’s cancer-fighting abilities, scientists are becoming expert at manipulating a patient’s own immune cells, turning them into cancer-killing armies. But cancers have tricks to evade attack, so scientists are racing to outmaneuver cancer and boost the effectiveness of immune cell therapies.

Cancer Stem Cells Get Energy From Protein, and it’s Proving to be their Achilles’ Heel

Aurora, CO, USA – Think of energy metabolism like a party popper: Ripping something apart releases a bang. Most of your cells rip apart sugar to release the “bang” of energy. A University of Colorado Cancer Center (UCCC) study published today in the journal Cancer Cell shows that cancer stem cells switch from metabolizing sugar to metabolizing protein, or more precisely amino acids, which are the building blocks of protein.

Investigator at Children's Hospital LA Awarded $1.3 Million to Study Stem Cell Therapy for Liver Failure

CHLA

San Francisco, CA, USA – Currently, the only therapy for metabolic liver disease is an organ transplant. Tracy Grikscheit, MD, an attending physician and regenerative medicine scientist at Children's Hospital Los Angeles, hopes to change that reality. She has been awarded nearly $1.3 million by the California Institute of Regenerative Medicine (CIRM) to study stem cell therapy for liver failure.
