Damaged leg muscles grew stronger and showed signs of regeneration in three out of five men whose old injuries were surgically implanted with extracellular matrix derived from pig bladder, according to a new study. Early findings are from a human trial of the process as well as from animal studies.

Possibly the most exciting use of stem cells rests on their ability to differentiate into an enormous range of healthy functioning adult cells, thereby providing a replacement source of cells to treat serious diseases. This ultimately means that virtually any disease that results in cellular and tissue destruction can potentially be treated by stem cells. Some of the conditions are particularly debilitating and these include diabetes, spinal cord injuries, retinal disease, Parkinson's disease, heart disease and cancer.

By observing how the cells in the zebrafish's skin responded to injury, the Duke team learned a lot about the skin regeneration process and were surprised by its complexity. They saw that in the hours following a fin amputation, for example, zebrafish regenerated skin through three different mechanisms: the "recruitment" of spare skin cells from other areas, a temporary doubling in size in some pre-existing cells, and the creation of completely new cells.

BodyMaps is an interactive visual search tool that allows users to explore the human body in 3-D. With easy-to-use navigation, users can search multiple layers of the human anatomy, view systems and organs down to their smallest parts, and understand in detail how the human body works. Using detailed 3-D models of body parts-including muscles, veins, bones, and organs-BodyMaps offers a new way to visualize and manage your health. See how the coronary artery delivers blood to the heart, and learn how plaque build-up on artery walls leads to heart disease. Locate the exact location of a pulled muscle or broken bone, and find information on how to prevent injuries. View a cross-section of the human brain, and learn which areas control certain emotions and body functions. By offering rich, detailed anatomical images alongside links to relevant and useful health information, BodyMaps allows you to leam about your body and your health in a personalized and revolutionary new way.

The treatment used olfactory ensheathing cells (OECs) - specialist cells that form part of the sense of smell. OECs act as pathway cells that enable nerve fibres in the olfactory system to be continually renewed. In the first of two operations, surgeons removed one of the patient's olfactory bulbs and grew the cells in culture. Two weeks later they transplanted the OECs into the spinal cord, which had been cut through in the knife attack apart from a thin strip of scar tissue on the right. They had just a drop of material to work with - about 500,000 cells.

CDC data visualization program presents a summary chart or table that is interactive. Different subsets of data can be displayed based on check menus. The focus is on the main causes of death, birth rates, and drug poisoning.
