How does a zebrafish grow a new tail?

...these simpler creatures, might still have untapped regenerative powers hidden in their genes. People are constantly renewing blood components, skeletal muscles and skin. We can regenerate liver tissue and repair minor injuries to bone, muscle, the tips of our toes and fingers, and the corneas of our eyes. Findi...

MIT creates 3-D scaffold for growing stem cells

...nment for tissue cell cultures and tissues used in regenerative medicine, such as skin grafts or neurons to replace brain cells lost to injury or disease. The scaffold itself can be transplanted directly into the body with no ill effects. "The time has come to move on from two-dimensional dishes to culture sy...

Fat stem cells being studied as option for breast reconstruction

...d of a type of extracellular matrix (ECM) that has regenerative properties. Preliminary results indicate that the stem cells can easily attach themselves to these beads and are able to differentiate into mature fat cells. When injected under the skin in a rat model, the cellular combination eventually formed what...

Adult stem cell research at UB targets damaged hearts

... therapy in the porcine hibernating myocardium and regenerative medicine for humans with chronic coronary artery disease will lead to optimized MSC therapeutics that can be of clinical value in managing aging and curing disease," he said. The research will be carried out in two phases. During the first phase, ...

Adult stem cells are touchy-feely, need environmental clues

...e in the bone marrow as part of the body's natural regenerative mechanism, depend on physical clues from their local environment in order to transform into different types of tissue. The researchers were even able to manipulate stem cells by changing the firmness of the gel on which they were grown. The researc...

Study finds how organs monitor themselves during early development

... them develop into germline stem cells, which have regenerative powers and others will differentiate into eggs. Signals, sensors, feedback A fruit fly takes ten days to go from embryo to larva to pupa to flying insect. The researchers looked at a larval development phase during which the ovary grows remark...

Progress being made in exploring potential use of stem cells to treat heart disease

... stem cells could prove effective as protective or regenerative cardiac therapies," says Ivey, who was named in April one of seven current postdoctoral fellows participating in the Gladstone's new stem cell training program, funded by the California Institute for Regenerative Medicine. "The adult heart seems to h...

Manchester scientists create new bio-gel for 3D cell culture

...ntial for future applications in wound healing and regenerative medicine." Dr Ulijn and his collaborators have successfully cultured cartilage cells using the gel. They found that both the properties of the gels formed and the cell response to the gels could be controlled by using different combinations of di-pe...

Potential heart benefit found in stem cells

...on after heart attacks. In a closer look at their regenerative function, researchers from Tulane University in Louisiana evaluated the stem cell transplant's effect on the thickness of the heart wall following a heart attack. To test the hypothesis, the researchers induced heart attacks in 17 pigs by way of an...

Rice bioengineers pioneer techniques for knee repair

...ssue engineers try to capitalize on the body's own regenerative powers to grow replacement tissues that can be transplanted without risk of rejection. Donor cells from the patient are used as a starting place to eliminate rejection risks. Most tissue engineering involves honeycombed plastic templates or hydrogel...

Scientists crack code for motor neuron wiring
