Researchers find stem cells remember prior substrates
Better tissue healing with disappearing hydrogels
When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a technique employed by a University of Rochester research team ...
A microchip for metastasis
Nearly 70 percent of patients with advanced breast cancer experience skeletal metastasis, in which cancer cells migrate from a primary tumor into bone—a painful development that can cause fractures and ...
Live imaging captures how blood stem cells take root in the body
A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood. Reporting online in the journal Cell today, researchers in Bos ...
Japan researchers target 3D-printed body parts
Japanese scientists say they are on their way to being able to create custom-made skin, bone and joints using a 3D printer.
New technique allows scientists to find rare stem cells within bone marrow
Deep within the bone marrow resides a type of cells known as mesenchymal stem cells (MSCs). These immature cells can differentiate into cells that produce bone, cartilage, fat, or muscle—a trait that scientists ...
New nanotube surface promises dental implants that heal faster and fight infection
A brighter, better, longer-lasting dental implant may soon be on its way to your dentist's office.
Scientists engineer nanoparticles to prevent bone cancer, strengthen bones
A research collaboration between Brigham and Women's Hospital (BWH) and Dana-Farber Cancer Institute (DFCI) has utilized nanomedicine technologies to develop a drug-delivery system that can precisely target and attack cancer ...
New insight on skull development in study of frogs
Chances are, you'd be hard-pressed to name something you have in common with a chicken. Would you believe that one answer is the head on your shoulders?
Team isolates stem cell that gives rise to bones, cartilage in mice
Researchers at the Stanford University School of Medicine have discovered the stem cell in mice that gives rise to bone, cartilage and a key part of bone marrow called the stroma.
A bio patch that can regrow bone
Researchers at the University of Iowa have created a bio patch to regenerate missing or damaged bone by putting DNA into a nano-sized particle that delivers bone-producing instructions directly into cells.
Targeting cancer's 'queen bees' with better tissue modeling
In many types of cancer, standard chemotherapy cures only a fraction of patients. Treatments are often too toxic to normal cells and they fail to selectively kill cancer's stem cells, which can survive treatment ...
Bone marrow-on-a-chip unveiled
The latest organ-on-a-chip from Harvard's Wyss Institute for Biologically Inspired Engineering reproduces the structure, functions and cellular make-up of bone marrow, a complex tissue that until now could ...
Matrix stiffness is an essential tool in stem cell differentiation, bioengineers report
Bioengineers at the University of California, San Diego have proven that when it comes to guiding stem cells into a specific cell type, the stiffness of the extracellular matrix used to culture them really ...
