The Key To Self-renewing Skin
2012-07-05 13:45:19

In the July 6 issue of Cell Stem Cell, researchers at the University of California, San Diego School of Medicine describe how human epidermal progenitor cells and stem cells control transcription factors to avoid premature differentiation, preserving their ability to produce new skin cells throughout life. The findings provide new insights into the role and importance of exosomes and their targeted gene transcripts, and may help point the way to new drugs or therapies for not just skin...

How a certain type of stem cell mobilizes in the circulation system of older people to repair damage from a heart attack or even to fight the aging process itself could hold the key to treating cardiac and other age-related diseases, according to a new study by researchers at Showa University in Japan. In an article published in the June issue of STEM CELLS Translational Medicine the researchers detail how, for the first time, they were able to home in on a protein called CD271 found on...

It is well-known that the risks of breast cancer increase dramatically for women over the age of 50, but what takes place at the cellular level to cause this increase has been a mystery. Some answers and the possibility of preventative measures in the future are provided in a new study by researchers at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). Mark LaBarge, a cell and molecular biologist in Berkeley Lab´s Life Sciences Division,...

Brown researchers have discovered mechanical properties of stem cells can foretell what they will become To become better healers, tissue engineering need a timely and reliable way to obtain enough raw materials: cells that either already are or can become the tissue they need to build. In a new study, Brown University biomedical engineers show that the stiffness, viscosity, and other mechanical properties of adult stem cells derived from fat, such as liposuction waste, can predict whether...

Cell surface protein blows potent cells' cover; targeted drug works in preclinical tests Breast cancer stem cells wear a cell surface protein that is part nametag and part bull's eye, identifying them as potent tumor-generating cells and flagging their vulnerability to a drug, researchers at The University of Texas MD Anderson Cancer Center report online in Journal of Clinical Investigation. "We've discovered a single marker for breast cancer stem cells and also found that it's...

Some cell types control continued tumor growth, others prepare the way for metastasis A study from Massachusetts General Hospital (MGH) researchers suggests that specific populations of tumor cells have different roles in the process by which tumors make new copies of themselves and grow. In their report in the May 15 issue of Cancer Cell, researchers identify a tumor-propagating cell required for the growth of a pediatric muscle tumor in a zebrafish model and also show that another,...

New research findings show that embryonic stem cells unable to fully compact the DNA inside them cannot complete their primary task: differentiation into specific cell types that give rise to the various types of tissues and structures in the body. Researchers from the Georgia Institute of Technology and Emory University found that chromatin compaction is required for proper embryonic stem cell differentiation to occur. Chromatin, which is composed of histone proteins and DNA, packages DNA...

Study Identifies Cell Subtypes For Potential Personalized Cellular Therapies
2012-05-10 04:47:04

Connie K. Ho for RedOrbit.com A new study by researchers at the University of California, Los Angeles (UCLA) has discovered two adult stem cell-like subpopulations in adult human skin. The findings allow for further research to be done in the area of personalized medicine and patient-specific cellular therapies. The study, using technology from Fibrocell Science, allowed the researchers to identify and confirm two types of cells in human skin cell cultures; the possible source of...
