Researchers use stem cells to regenerate muscle tissue in rats
A study in the journal Acta Biomaterialia suggests that stem cells can be mobilized to promote regeneration of damaged muscle tissue. Wake Forest Baptist Medical Center researchers developed scaffolds enriched with myogenic factor and implanted them in the tibialis anterior muscles of rats, and host stem cells and blood vessels developed after four weeks. Researchers hope the technique could lead to similar therapies for human applications. Gizmag (9/7)

U.K. researcher: Lack of public awareness hinders tissue donation
Donated heart valves, eyes, skin, bone and other tissues are critical to transplants and disease research, but a lack of knowledge about the difference between tissue and organ donation can be an obstacle for potential donors, University of Southampton research fellow Tracy Long-Sutehall writes. To address the issue, it is crucial to inform the public about the process of tissue donation, its challenges and benefits, Long-Sutehall writes. The Conversation (Australia) (9/8)

BBC's "Human Tissue Squad" shares story of donation
The two-part BBC documentary "The Human Tissue Squad" follows the work of a U.K. National Health Service tissue bank in Liverpool and the patients who can benefit from donations. The show features nurses who contact families, tissue retrieval specialists and order specialists who coordinate with hospitals. "[W]hen you see how many lives one person's donation can help, it is pretty amazing," retrieval specialist Adam Edwards said.

Study: Skin cells can be converted into pulmonary valves for children
In a study published in the journal Annals of Thoracic Surgery, researchers created a tissue-engineered pulmonary valve through skin cells taken from a child's biopsy. Since the valve is capable of growing with the patient, it curbs children's odds of undergoing valve replacements later in life. HealthDay News (9/3)

Signaling pathway linked to loss of muscle stem cells with age
Muscle stem cells, or satellite cells, become less effective at repairing damaged tissue as people age. A study in the journal Nature Medicine suggests the cause is increased activity in the JAK/STAT signaling pathway, which leads to the production of fewer stem cells as the satellite cells divide.

CDC: More young people are being diagnosed with hepatitis C
CDC data showed hepatitis C rates are rapidly increasing in people ages 30 and younger and new infections are strongly related to injection drug use. Researchers said 30 out of 34 reporting states and territories had higher acute HCV rates among younger persons in 2012 than in 2006, and some states had increases ranging from 100% to more than 200%.
