Stem cell research shows promise for tissue-engineered vascular grafts
Researchers are the first to fully characterize a special type of stem cell, endothelial progenitor cells (EPCs) that exist in circulating blood, to see if they can behave as endothelial cells in the body when cultured on a bioengineered surface. The results show promise for a new generation of tissue-engineered vascular grafts which could improve the success rate of surgery for peripheral arterial disease.
A sporting chance for active total knee replacement patients
Total knee arthroplasty patients may be able to participate in high-impact sports without increasing risk of early implant failure, according to a new study.
Different fat types can help or hinder obese girls' bone health
Obese teenage girls with a greater ratio of visceral fat (fat around internal organs) to subcutaneous fat (fat found just beneath the skin) are likely to have lower bone density than peers with a lower ratio of visceral to subcutaneous fat, according to a new study.
Discovery of cellular 'switch' may provide new means of triggering cell death, treating disease
Scientists have discovered a previously unknown cellular "switch" that may provide researchers with a new means of triggering programmed cell death, findings with implications for treating cancer.
Designer nano luggage to carry drugs to diseased cells
Scientists have succeeded in growing empty particles derived from a plant virus and have made them carry useful chemicals. The external surface of these nano containers could be decorated with molecules that guide them to where they are needed in the body, before the chemical load is discharged to exert its effect on diseased cells. The containers are particles of the Cowpea mosaic virus, which is ideally suited for designing biomaterial at the nanoscale.
