USC researchers identify mechanism that controls activation of stem cells during hair regeneration
01-16-2008 · EurekAlert!Researchers at the University of Southern California have identified a novel cyclic signaling in the dermis that coordinates stem cell activity and regulates regeneration in large populations of hairs in animal models.

- Loss of cell's 'antenna' linked to cancer's development
06-28-2007 · EurekAlert!
Most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth. In a new study published in the June 29 issue of Cell, Fox Chase Cancer Center researchers describe the strong link between ciliary signaling and cancer, and identify the rogue engineers responsible for dismantling the cell's antenna.

- Protein maintains cross talk between cells that control hair growth
02-14-2008 · EurekAlert!
Researchers at Rockefeller University have identified a signaling molecule that is critical for a type of skin cell, called dermal papilla, to ratchet up or clamp down the activity of genes that give them their molecular identity. Without these signals, these skin cells lose their hair-inducing properties -- findings that may provide a new understanding of how stem cells differentiate.

- USC-led researchers use stem cells to regenerate parts of teeth
12-20-2006 · EurekAlert!
A multi-national research team headed by USC School of Dentistry researcher Songtao Shi, DDS, PhD, has successfully regenerated tooth root and supporting periodontal ligaments to restore tooth function in an animal model. The breakthrough holds significant promise for clinical application in human patients.

- Scientists identify a mouse embryonic stem cell more like our own
06-27-2007 · EurekAlert!
Scientists have discovered a new type of mouse embryonic stem cell that is the closest counterpart yet to human embryonic stem cells, the National Institutes of Health announced today. The cells are expected to serve as an improved model for human ES cells in studies of regeneration, disease pathology and basic stem cell biology.

- Human embryonic stem cell -- derived bone tissue closes massive skull injury
12-02-2007 · EurekAlert!
There are mice in Baltimore whose skulls were made whole again by bone tissue grown from human embryonic stem cells. Healing critical-size defects, which would not otherwise heal on their own, in intramembraneous bone, the flat bone type that forms the skull, is a vivid demonstration of new techniques devised by researchers using hESCs for tissue regeneration.

- Getting one's protein in a bunch -- When quality control fails in cells
01-16-2007 · EurekAlert!
Over time, a relatively minor mistake in protein production at the cellular level may lead to serious neurological diseases. But exactly how the cell avoids such mistakes has remained unclear until now. Researchers at Ohio State University found the mechanism that prevents such errors, and explain their findings in the Proceedings of the National Academy of Sciences.

- Researchers Uncover Critical Player In Cell Communication
10-06-2006 · ScienceDaily
Johns Hopkins researchers have teased out the function of a protein implicated in Williams-Beuren syndrome, a rare cognitive disorder associated with overly social behavior and lack of spatial awareness. Called TFII-I, or TF "two eye," the protein long known to help control a cell's genes also controls how much calcium a cell takes in, a function critical for all cells, including nerves in the brain. The study will be published this week in Science.

- Stem cells found in adult hair follicles may provide alternative to embryonic stem cells
12-11-2006 · EurekAlert!
A team from the Medical College of Wisconsin in Milwaukee has applied for a patent on their work to isolate, grow and identify a new and readily-available type of adult stem cell that is found in the bulge of hair follicles, and appears to have a potential for diversification similar to that of embryonic stem cells.

- USC researcher identifies stem cells in tendons that regenerate tissue in animal model
09-09-2007 · EurekAlert!
A consortium of scientists, led in part by USC School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell characteristics -- including the ability to proliferate and self-renew. The research team was able to isolate these cells and regenerate tendon-like tissue in the animal mode.

- Molecular 'marker' on stem cells aids research, perhaps therapies
12-04-2006 · EurekAlert!
A sugar molecule present on embryonic stem cells also has been found on the surface of a type of adult stem cell, a discovery that may help researchers isolate and purify adult stem cells for use in therapies aimed at bone healing, tendon repair and cartilage regeneration, researchers at UT Southwestern Medical Center report.
