Something Good And Fishy Is Happening Here

Since one of my kidney world contacts brought my attention to Bioscholar.com, I’ve been going to the site periodically to find interesting, innovative, and imperative (nice alliteration, huh?) news about kidneys.   I think I found a winner this time.

New findings offer hope to patients with damaged kidneys

Wednesday, February 2nd, 2011

 
 
Scientists have discovered a cell in zebrafish that can be transplanted from one fish to another to regenerate nephrons and improve kidney function.

Many non-mammalian vertebrates generate nephrons throughout their lives and can generate new nephrons following renal injury.

Understanding how non-mammalian vertebrates like zebrafish carry out this remarkable regenerative process and why mammals have lost this ability might provide new ways to repair damaged human kidneys and dramatically extend and improve the lives of hundreds of thousands of patients with chronic renal failure.

Researchers at Brigham and Women’s Hospital, Massachusetts General Hospital and the University of Pittsburgh have identified and characterized, for the first time, a progenitor cell in adult zebrafish kidneys that can be transplanted from one fish to another and generate new nephrons.

Now that this cell has been identified it may be possible to better understand how to increase its number and capacity to generate nephrons.

Lead author, Alan Davidson, said, “We hope to eventually be able to cross species barriers and understand why similar cells, present in mouse and human kidneys during embryonic life, disappear around the time of birth”.

The groups plan to continue studies on zebrafish and apply their data to mouse models and eventually humans.

The findings have been published in the journal Nature.

This is Wikipedia’s entry about the journal: 

Nature (journal)

From Wikipedia, the free encyclopedia

 

For the U.S. magazine published in Baltimore between 1923–1959, see American Nature Association.

Nature, first published on 4 November 1869, is the world’s most cited interdisciplinary science journal. Most scientific journals are now highly specialized, and Nature is among the few journals (the other weekly journals Science and Proceedings of the National Academy of Sciences are also prominent examples) that still publish original research articles across a wide range of scientific fields. There are many fields of scientific research in which important new advances and original research are published as either articles or letters in Nature.

Research scientists are the primary audience for the journal, but summaries and accompanying articles are intended to make many of the most important papers understandable to scientists in other fields and the educated general public. Towards the front of each issue are editorials, news and feature articles on issues of general interest to scientists, including current affairs, science funding, business, scientific ethics and research breakthroughs. There are also sections on books and arts. The remainder of the journal consists mostly of research articles, which are often dense and highly technical. Because of strict limits on the length of articles, often the printed text is actually a summary of the work in question with many details relegated to accompanying supplementary material on the journal’s website.

In 2007 Nature (together with Science) received the Prince of Asturias Award for Communications and Humanity.

Keeping in mind that Wikipedia is open to editing anonymously by anyone, this information about the journal has the ring of truth to it.  Of course, I researched it to the best of my ability. It looks like it’s purely online now at: http://www.nature.com/nature/about/index.html. I’m not scientifically oriented (except for Chronic Kidney Disease), but still found it   fascinating.  Take a look for yourself.

Until Friday,

Keep living your life.
