RIKEN Stem cells have the unique ability to become any type of cell in the body. Given this, the possibility that they can be cultured and engineered in the laboratory makes them an attractive option for regenerative medicine. However, some conditions that are commonly used for culturing human stem cells have the potential to introduce contaminants, thus rendering the cells unusable for clinical use. These conditions cannot be avoided, however, as they help maintain the pluripotency of...

Rice University Rice University scientists apply new theory to learn how and why cells differentiate How does a stem cell decide what path to take? In a way, it’s up to the wisdom of the crowd. The DNA in a pluripotent stem cell is bombarded with waves of proteins whose ebb and flow nudge the cell toward becoming blood, bone, skin or organs. A new theory by scientists at Rice University shows the cell’s journey is neither a simple step-by-step process nor all random....

Tai Chi May Help Slow The Aging Process

April Flowers for redOrbit.com - Your Universe Online Tai Chi Chuan, or Tai Chi as it is commonly known, is an ancient form of Chinese martial arts. Originally developed as a form of self-defense, today Tai Chi has become a graceful exercise used to reduce stress and other health concerns, according to the Mayo Clinic. A new study from the China Medical University Hospital reveals that Tai Chi also results in an increased expression of cluster of differentiation 34 (CD34+) cells, a stem...

University of Cambridge A new method of generating mature nerve cells from skin cells could greatly enhance understanding of neurodegenerative diseases, and could accelerate the development of new drugs and stem cell-based regenerative medicine. The nerve cells generated by this new method show the same functional characteristics as the mature cells found in the body, making them much better models for the study of age-related diseases such as Parkinson's and Alzheimer's, and for the...

Male Fertility Relies On A Key Protein That Also Protects Against Disease
2014-05-13 10:58:14

Brett Smith for redOrbit.com - Your Universe Online Male infertility prevents many couples from being able to conceive a child and a new study published in the journal Nature Communications has found a specific protein that is a major determining factor in determining a sperm’s ability to fertilize an egg. The protein, known as Chd5, is responsible for effectively packaging DNA inside the head of a sperm, where space it at a premium. Each cell in the body contains an entire copy of...

Salk scientists find two key proteins that regulate the growth of mammary stem cells and could contribute to breast cancer By carefully controlling the levels of two proteins, researchers at the Salk Institute have discovered how to keep mammary stem cells—those that can form breast tissue—alive and functioning in the lab. The new ability to propagate mammary stem cells is allowing them to study both breast development and the formation of breast cancers. "What we've shown is that...

Findings and Significance: During breast-tissue development, a transcription factor called SLUG plays a role in regulating stem cell function and determines whether breast cells will mature into luminal or basal cells. Studying factors, such as SLUG, that regulate stem-cell activity and breast-cell identity are important for understanding how breast tumors arise and develop into different subtypes. Ultimately, this knowledge may help the development of novel therapies targeted to specific...

Stem Cells Of Infertile Men Used To Create Preliminary Sperm Cells
2014-05-02 08:25:30

April Flowers for redOrbit.com - Your Universe Online A new study, from the Stanford University School of Medicine and Montana State University, demonstrates that, when implanted into the reproductive system of a mouse model, stem cells created from adult, infertile men will yield primordial germ cells. Primordial germ cells normally become sperm cells. The findings, published in Cell Reports, help to further our understanding of a genetic cause of male infertility and basic sperm...

Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body. Now, in a feat of reverse tissue engineering, Stanford University researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform myriad biological tasks. A team of...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
