(Ivanhoe Newswire) -- There's a new "first" in the world of tissue engineering. Researchers have used patients' own cells to build tailor-made urinary tubes and successfully replace damaged tissue. The research team, from the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Center, reported replacing damaged segments of urethras in five boys aged 10 to 14. Tests that measured urine flow and tube diameter revealed the engineered tissue remained functional...

Cells at the tip of the slime mold's fruiting body organize into an epithelial layer and secrete proteins as do some animals cells The so-called cellular slime mold, a unicellular organism that may transition into a multicellular organism under stress, has just been found to have a tissue structure that was previously thought to exist only in more sophisticated animals. What's more, two proteins that are needed by the slime mold to form this structure are similar to those that perform the...

In biology, the key to a healthy life is organization. Cells that properly organize themselves into communities live long and prosper, whereas disorganized cells can become cancerous. A study by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) of the different types of cells that make up the human breast  shows that not only do cells possess an innate ability to self-organize into communities, but these communities of different types of cells can also organize...

Researchers at the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Center and colleagues reported today on a new advance in tissue engineering. The team is the first in the world to use patients' own cells to build tailor-made urinary tubes and successfully replace damaged tissue. In an article published Online First by The Lancet, the research team reports replacing damaged segments of urinary tubes (urethras) in five boys. Tests to measure urine flow and tube...

The intestinal epithelium consists of four main specialized cell lineages: absorptive enterocytes and three secretory cell types known as enteroendocrine, Paneth, and goblet cells. But a rare, fifth type of intestinal cell called tuft cells also exists. Defined by the thick brush of long microvilli that project from their apical surface, tuft cells are seen in several epithelial tissues, yet little is known about their function due to a lack of tuft cell"“specific markers. In the March...

Foregut duplication cyst of the stomach is rare. Foregut duplications may or may not communicate with the gastrointestinal tract, and are usually diagnosed at a young age. There have been relatively few case reports describing this entity. Adenocarcinoma has been reported in four cases of gastric duplication cyst, but not in cysts that have a ciliated epithelium. Controversy exists concerning the embryological origin of these anomalies. A research article to be published on January 7, 2011 in...

Researchers at Mayo Clinic in Florida have found that a molecule long believed to be a beneficial tumor suppressor "” and thus a potential cancer drug target "” appears to act as an oncogene in some lethal brain tumors. The protein, epithelial cadherin (E-cadherin), is known for its ability to keep cancer cells glued together, preventing them from breaking away and metastasizing. But, based on their findings, published online in PLoS ONE, the scientists suggest E-cadherin can also...

In a study to be published online Oct. 21 in PLoS Genetics, researchers at the Stanford University School of Medicine have implicated the lack of a protein important in hooking our skin cells together in the most common variety of skin cancer. Depletion of this protein, called Perp, could be an early indicator of skin cancer development, and could be useful for staging and establishing prognoses. These findings' significance may extend beyond skin cancer, as Perp is found in the linings of...

Scientists at the Stanford University School of Medicine have pushed into place another piece of the puzzle of how Listeria monocytogenes, a dangerous food-borne pathogen, slips through the intestine's defenses and causes disease. Listeria monocytogenes is a hardy, if unwelcome, brunch guest. This bacterial strain thrives in salty or cold environments where prissier pests might perish: cold cuts, smoked salmon, soft cheeses and many a refrigerator. Abundant in the environment, it seldom...

Probiotics are a group of live microorganisms administered in adequate amounts which confer a beneficial health effect on the host. This bacterial community plays a pivotal role in human nutrition and health by promoting the supply of nutrients, preventing pathogen colonization and shaping and maintaining normal mucosal immunity. While the precise mechanistic basis of the beneficial effects of probiotics is obscure and will most likely vary depending on the strain and species used. A research...
