Stem cells used to grow new windpipe for British teen with cancer

The 19-year-old has now been discharged after having the procedure in Italy. She was suffering from a rare form of trachea cancer and would have died without the operation. Doctors took tissue from her nose and bone marrow stem cells to create a trachea …

A Novel Airway Stem Cell Discovered By Scientists At The Broad Stem Cell Research Center At UCLA

A new type of pulmonary stem cell has been identified by scientists at UCLA. These cells have a potential to regenerate large damaged airways and play an important role in strengthening immunity against infectious agents and environmental toxins. Mucous secretion and clearing by the airways is a protective mechanism against pathogens and environmental toxins…

Adult stem cells carry their own baggage: Epigenetics guides stem cell fate

Adult stem and progenitor cells may not contain a clean genetic slate after all. A new report shows that these cells have unique “epigenetic signatures,” which change once a cell differentiates. Epigenetic changes do not affect the make up in a cell’s DNA, but how that DNA functions. Epigenetic changes have demonstrated a role in a range of diseases, as well as to be heritable from mother to child.

Stem Cell Breakthrough Shows Multi Regen Of Nervous System Neurons

Stem cell research seems like it is not going anywhere fast. In fact breakthroughs are being announced more and more frequently. This week a Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing …

DeGette promotes new bill on stem cell research – AP

Colorado congresswoman Diana DeGette is again sponsoring legislation promoting embryonic stem cell research. The Democrat announced her bill Wednesday at Craig Hospital in Englewood. The suburban hospital is a nationally known rehabilitation and research …

Rep. DeGette renews bid to pass stem-cell legislation

U.S. Rep. Diana DeGette on Wednesday unveiled her latest legislative effort to support embryonic-stem-cell research. The Denver Democrat used Craig Hospital, which is internationally acclaimed for its rehab facilities for people with spinal- cord and brain …

The Promise Of Stem Cell-Based Gene Therapy Will Depend On Novel Gene Delivery Tools

Sophisticated genetic tools and techniques for achieving targeted gene delivery and high gene expression levels in bone marrow will drive the successful application of gene therapy to treat a broad range of diseases…

New Stem Cell Key To Lung Regeneration

A new stem cell that could be playing a key role in lung regeneration has been identified by researchers at the University of California, Los Angeles (UCLA). The airways protect the body by producing and clearing mucus from the airways. The mucus is …

Adult stem cells effective against clogged leg arteries

LOS ANGELES (KABC) — At its worst, clogged leg arteries can cause dangerous complications like severe pain, gangrene, even loss of limbs. It’s treated with lifestyle changes, exercise and medications to surgical interventions. Now for patients with the …

Growing Older: Stem cells and quacks

When it comes to cellular biology, I confess profound ignorance. The subject, undeveloped when I did my schooling, escaped me almost entirely. I am awed when I hear the human body contains 10 trillion cells, but I have only the vaguest idea what cells look …
