Scientists find a groovy way to influence specialization of stem cells

December 18, 2013 by · Leave a Comment 

Researchers at Queen Mary University of London have shown for the first time that the specialised role stem cells go on to perform is controlled by primary cilia – tiny hair-like structures protruding from a cell.

Mayo Clinic and collaborators develop new tool for transplanting stem cells

December 17, 2013 by · Leave a Comment 

Mayo Clinic researchers and colleagues in Belgium have developed a specialized catheter for transplanting stem cells into the beating heart. The novel device includes a curved needle and graded openings along the needle shaft, allowing for increased distribution of cells. The result is maximized retention of stem cells to repair the heart. The findings appear in the journal Circulation: Cardiovascular Interventions.

Researchers unlock a new means of growing intestinal stem cells

December 2, 2013 by · Leave a Comment 

Researchers at MIT and Brigham and Women’s Hospital have shown that they can grow unlimited quantities of intestinal stem cells, then stimulate them to develop into nearly pure populations of different types of mature intestinal cells. Using these cells, scientists could develop and test new drugs to treat diseases such as ulcerative colitis.

Physical cues help mature cells revert into embryonic-like stem cells

October 21, 2013 by · Leave a Comment 

Bioengineers at the University of California, Berkeley, have shown that physical cues can replace certain chemicals when nudging mature cells back to a pluripotent stage, capable of becoming any cell type in the body.

Stem cell reprogramming made easier

September 19, 2013 by · Leave a Comment 

Embryonic stem cells have the enormous potential to treat and cure many medical problems. That is why the discovery that induced embryonic-like stem cells can be created from skin cells (iPS cells) was rewarded with a Nobel Prize in 2012. But the process has remained frustratingly slow and inefficient, and the resulting stem cells are not yet ready for medical use. Research in the lab of the Weizmann Institute’s Dr. Yaqub Hanna, which appears today in Nature, dramatically changes that: He and his group revealed the “brake” that holds back the production of stem cells, and found that releasing this brake can both synchronize the process and increase its efficiency from around 1% or less today to 100%. These findings may help facilitate the production of stem cells for medical use, as well as advancing our understanding of the mysterious process by which adult cells can revert back into their original, embryonic state.

Truly Pluripotent Stem Cells – A Pending Breakthrough

June 11, 2013 by · Leave a Comment 

Stem Cell Research may soon be coming into a new level of progress. A new discovery of what seems to be genuinely pluripotent stem cells coined as MUSE-AT (multilineage-differentiating stress-enduring cells, derived from adipose tissue is an imminent breakthrough in the ongoing multi-million and multi-national regenerative medicine research.

Recipe for large numbers of stem cells requires only one ingredient, says NIH/Pitt team

April 17, 2013 by · Leave a Comment 

Stem cells and tissue-specific cells can be grown in abundance from mature mammalian cells simply by blocking a certain membrane protein, according to scientists at the University of Pittsburgh School of Medicine and the National Institutes of Health (NIH). Their experiments, reported today in Scientific Reports, also show that the process doesn’t require other kinds of cells or agents to artificially support cell growth and doesn’t activate cancer genes.

IUPUI stem cell research could expand clinical use of regenerative human cells

March 19, 2013 by · Leave a Comment 

Research led by a biology professor in the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) has uncovered a method to produce retinal cells from regenerative human stem cells without the use of animal products, proteins or other foreign substances, which historically have limited the application of stem cells to treat disease and other human developmental disorders.

Key protein revealed as trigger for stem cell development

February 7, 2013 by · Leave a Comment 

A natural trigger that enables stem cells to become any cell-type in the body has been discovered by scientists.

Studying marrow, URMC researchers accelerate blood stem cells

December 6, 2012 by · Leave a Comment 

University of Rochester Medical Center scientists are testing a new approach to speed a patient’s recovery of blood counts during a vulnerable period after a stem-cell transplant, according to a study published in the journal Stem Cells.
