Great News on Stem Cells!

It's something long overdue--- federal support for human embryonic stem cell research. We've discussed many of the arguments pro and con. But in the end, science has to progress without the restrictions of religious ideology. And everyone, even those who believe that a 100-cell embryo is equivalent to a human baby, will benefit from the medical knowledge gained.

I'm Baaaaack!

Thanks to Heather for bringing me back from hiatus.  Life is hectic with two jobs, located 70 miles apart.  But at least the gas prices have come down a bit.

I'm hopeful with the new administration coming in 2009 that stem cell research will be supported at the federal level in short order.  

Here is some recent good news on the use of stem cells to reconstruct a human trachea:

Long Time, No Blog!

Greetings from Stem Cell Central!

I didn't realize how long it's been since my last post. The two jobs have been keeping me busy.

Here's the website for NYSTEM, the New York State stem cell initiative that was established in April 2007:
http://stemcell.ny.gov/

NYSTEM has recently put out a request for grant proposals for New York State stem cell researchers.
http://stemcell.ny.gov/news_releases.html

ALBANY, NY (May 8, 2008) Governor David A. Paterson today announced that nearly $109 million in new state funding is being made available to support stem cell research initiatives in New York. The nearly $109 million represents the second round of available funding from the state’s 11-year, $600 million stem cell research initiative that was approved as part of last year’s state budget.

Four Requests for Applications (RFAs) issued today invite proposals from in-state research institutions for stem cell research activities that encourage collaborations among scientists, facilitate the acquisition and development of specialized equipment, and support researcher-initiated and targeted stem cell research

It's great to see the New York State stem cell initiative come to fruition, thanks to the tireless efforts of so many advocates.

Academia in a Nutshell

Oldies But Goodies

Cornea transplants are routine, with the highest success rates (97-99%) of any transplant procedure. In general, corneas for transplant are obtained from eyebank donors, aged 2-70. A recent study suggests that corneas from older donors may work as well as corneas from younger donors.

Some kinds of cornea damage and prior LASIK surgery disqualify corneas from being used as transplant material. As more and more people decide to undergo LASIK kinds of procedures, fewer corneas will qualify as transplant material. By increasing the potential donor age, it will help address potential shortages.

"We now have scientific evidence showing that older donors can be used reliably in corneal transplantation," said Dr. Edward Holland of the University of Cincinnati and one of the study's lead researchers.

The cornea is the clear covering for the front of the eye, crucial for helping it focus light. More than 39,000 corneal transplants were performed last year, according to the Eye Bank Association of America.

The nation has had an adequate supply so far. But specialists say there are international shortages, and eye banks fear U.S. supplies will tighten as a result of tougher Food and Drug Administration donor-safety rules that began last summer, increasing interest in older donors.

This is interesting in light of some of the research done in my own lab a few years ago, where we saw stem-like cells in corneas from 92-year old donors. It's amazing how the cornea is able to maintain its clarity and vitality throughout life....and even beyond.

Annual Marshmallow Peeps Post

I discovered this silly website a couple of years ago. It's still hysterical and especially appropriate for Easter week-end. It seems that some scientists (apparently with some time to kill in the lab) are conducting laboratory experiments on marshmallow peeps. They have an entire website devoted to their studies.

One particularly cute experiment was "the effect of alcohol and smoking on marshmallow peeps."
http://www.peepresearch.org/smoking.html

First, the peep was exposed to alcohol and did exhibit some signs of inebriation, such as bumping into the walls of the swimming vessel:



Then, the peep was permitted to select a brand of cigarette and smoked without apparent ill effects:


However, when smoking and alcohol were combined, the effects were catastrophic:

Their conclusions: "The synergistic effect of smoking and alcohol in Peeps produces a rapidly exothermic oxidation reaction, leading to a chemical and morphological divergence from the wild-type Peep phenotypes."

The marshmallow peep appears to be an excellent experimental model for the synergistic effects of smoking and alcohol!

Great News!!

Hey, guess what? I just found out that my research grant is going to be funded!! Yay! This is good news because I can finally hire some technical help for the stem cell lab and not be a volunteer anymore. It's time to celebrate!

The research project involves targeting "cancer stem cells" that seem to be the driving force behind tumor growth and resistance to chemotherapy.

It's All Relative!

How many of you out there have blue eyes? If so, we're related!

A Danish scientist, Dr. Hans Eiberg, has conducted a study of blue-eyed people and found that there is a single mutation responsible for blue eye color. This mutation is very specific and has been found in every single blue-eyed person that they've studied. This "founder" mutation for blue eyes goes back to a common ancestor thousands of years ago. In other words, if you have blue eyes, you are likely related to everyone else in the world who also has blue eyes.

Everything You Always Wanted to Know About Stem Cells....

This is a long, but interesting presentation that explains stem cells.

Clone, Clone on the Range

How do you feel about eating hamburgers from cloned cows?

Meat from cloned animals has been deemed no different than meat from non-cloned animals. Therefore, the FDA requires no special label for cloned meat.

So why clone animals?

The idea is to replicate the best livestock over and over again, to improve the quality of meat and milk products.

There are some who feel squeamish about cloning animals, worry about safety issues, and wonder whether cloned animals face increased danger from being wiped out by epidemics. Some want mandated labeling so that they will know whether or not their meat comes from cloned animals.

With the caveat of ensuring genetic diversity in animals to protect against epidemics, I am comfortable with cloned animals. On the grill, a steak from a cloned animal is indistinguishable from a steak from an uncloned animal. Twin cows are clones of one another. There is no inherent danger to humans in eating meat from twin cows, whether naturally-occurring or intentionally created.

Here is an interesting video from Wired Science that explains things in a bit more detail--

Bird Flu

Eight suspected cases of bird flu have been reported in Pakistan, including five members of one family. One relative, who attended a funeral for one of the flu victims in Pakistan and returned to New York, developed flu-like symptoms and went into voluntary quarantine with his son. Tests for exposure to bird flu were negative for both father and son and they are no longer in quarantine. There is more detail on this story at Bloomberg.com

According to the World Health Organization, approximately 340 people in 13 countries have contracted bird flu since 2003. Sixty percent of the cases were fatal and most could be traced to direct contact with infected poultry. At this point, bird flu has not become a highly contagious, seasonal event. But we certainly need to keep tabs on it.

In April of this year, the Centers for Disease Control announced FDA approval for the first human bird flu vaccine against the H5N1 strain of the virus. According to the FDA:

The manufacturer, sanofi pasteur Inc., will not sell the vaccine commercially. Instead, the vaccine has been purchased by the federal government for inclusion within the National Stockpile for distribution by public health officials if needed.

"The threat of an influenza pandemic is, at present, one of the most significant public health issues our nation and world faces," said Andrew C. von Eschenbach, M.D., Commissioner of Food and Drugs. "The approval of this vaccine is an important step forward in our protection against a pandemic."

News On The Stem Cell Front

I'll bet many of you have read the latest news stories about how skin cells have been coaxed to behave like embryonic stem cells. This is a fascinating study and one that bears follow-up in the months/years ahead.

However, contrary to President Bush's recent comments, these findings do not eliminate the need for human embryonic stem cell research, nor will it end the stem cell debate. In order to prove that these new skin-derived stem cells are as good as, or better than, human embryonic stem cells, direct comparisons must be made between them under a variety of conditions. In order to make direct comparisons, all stem cell types are needed, embryonic and otherwise. To limit further study on skin-derived stem cells alone, it would never allow us to answer the question of which cell type might work best for diabetes, Parkinson's Disease, spinal cord injury, etc.

In no way does this minimize the significance of findings regarding skin-derived stem cells or stem cells derived from other tissue types. But I do think that it's important to ensure that stem cell researchers have access to a wide variety of cell types for future study, including human embryonic stem cells. Let's keep this issue at the forefront and encourage federal funding for all stem cell research.

R.I.P Washoe

Washoe the chimp died on Oct. 30th at the age of 42. She was the first non-human to learn American Sign Language (ASL). She was named for Washoe county, Nevada, where she was raised and trained in ASL. At the time of her death, she resided at Central Washington University.

There was controversy about the project and the claims that Washoe could use 250 ASL signs. Still, the project was groundbreaking in the field of animal communications. Washoe eventually passed on her knowledge of ASL to her adopted son Loulis.

Happy Birthday...Have a Nobel Prize!

It was a great birthday for Gerhardt Ertl. He turned 71 today and was awarded the Nobel Prize in chemistry. His award-winning research involved "surface chemistry", vital to the development of the catalytic converter, and our understanding of the vanishing ozone layer.

Professor Ertl spoke at a live press conference today, "It is the best birthday present that you can give somebody. I was really speechless."

Happy Birthday, Professor Ertl!

Breast Cancer Walk-- A Success!

I participated in today's "Making Strides for Breast Cancer" walk to benefit the American Cancer Society. You can see from the photo that we had perfect weather for the event. I walked the 3 mile route with a group of about 14 team members, including a couple of toddlers in a stroller. Altogether, there were about 9,000 people who took part in our local walk.

Many thanks to all who sponsored me. I ended up raising over $700 for a very worthy cause.

In Memoriam: Elizabeth Olmsted

From the Buffalo News Obituary:

March 5, 1915 — Sept. 6, 2007

Dr. Elizabeth Pierce Olmsted, a pioneer for women in medicine, died Thursday in Millard Fillmore Hospital. She was 92.

She graduated from the University of Buffalo School of Medicine in 1939, becoming Western New York’s first female ophthalmologist.

Throughout her career, she also worked as a military consultant investigating the effects of radar exposure on the eye, invented the diffraction lens used in the treatment of crossed and lazy eyes, authored numerous articles and served as president and chairwoman of local and state professional societies.

Dr. Olmsted was one of the area’s first female pilots, serving as a lieutenant in the Civil Air Patrol in the early 1940s. She was a member of the Ninety- Nines, the international organization of female pilots.

Her husband, Ira G. Ross, died in 1991.

A lifelong Buffalo resident and civic leader, she volunteered for several local organizations. Of all her accomplishments, she is perhaps best known for philanthropy.

Throughout the 1990s, Dr. Olmsted contributed millions of dollars to the UB School of Medicine and Biomedical Sciences to establish a faculty chair in medical information services and to establish the Ira G. Ross Eye Institute. She also donated to the Blind Association of Western New York, renamed in her honor the Elizabeth Pierce Olmsted, M.D. Center for the Visually Impaired, to update its facility to state-of-the-art.

In recognition of her generosity, Dr. Olmsted in 2004 received the Outstanding Philanthropist Award from the Association of Fundraising Professionals.

She also received the National Conference for Community and Justice of Western New York Lifetime Achievement Award, the Athena Award, UB’s Distinguished Medical Alumna Award and many other honors. In 2003, she received an honorary doctorate in science from the State University of New York.

I had the great pleasure to know Dr. Olmsted. She once told me that when she started out as the first female Ophthalmology resident at the University of Rochester, the male residents refused to sit at the lunch table with her. Eventually, she won them over. She was truly a pioneer in the field.
