Miami Beach, Fla.Finding a way to restore hair growth after substantial hair loss is something of an obsession worldwide. Investigators at the Society of Nuclear Medicine's 2012 Annual Meeting presented how stem cell research for the development of new hair follicles can be monitored with an optical imaging technique that uses bioluminescence, the same process that allows fireflies to light up.

There is a host of treatments available for hair loss, including creams and drugs, but these have not shown to be very effective for hair growth. Hair stem cells signal the actual regeneration of hair follicles and natural hair. A molecular imaging technique called bioluminescence is used to display processes at the cellular level. Bioluminescent signal is generated in specific chemical substances called substrates. These signals are easily recognized with very sensitive optical imaging systems that can see what is happening in the smallest placesin this case in hair stem cells.

"Hair regeneration using hair stem cells is a promising therapeutic option emerging for hair loss, and molecular imaging can speed up the development of this therapy," saysByeong-Cheol Ahn, M.D., Ph.D., professor and director of the department of nuclear medicine at Kyungpook National University School of Medicine and Hospital in Daegu, South Korea. "This study is the first study of hair follicle regeneration using an in vivo molecular imaging technique."

The current research involves grafting hair stem cells in animal models to investigate if they can grow and proliferate as normal cells do. The progress of hair stem cell therapy is non-invasivelytracked with bioluminescentreporter genes in specialized substrates. There are several bioluminescent reporter genes originating fromnot only fireflies, but also beetles, glowworms and other bioluminescent organisms. The strategy of using bioluminescent reporter genesis ideal for stem cell research, because bioluminescence works only in living cells.

In this study, researchers used bioluminescence imaging usingfirefly luciferase coupled with D-luciferin to monitor the engraftment of hair follicle stem cellscalled newborn fibroblastsin mice to track their viability and development into hair folliclesover time. Bioluminescence imaging was performed five times over the course of 21 days after transplantation of the stem cells.

Results of the study showed successful bioluminescence imaging forhair regeneration with hair stem cell transplantation, and new hair follicles were apparent on the surface of skin samples under microscope. More studies will have to be conducted before clinical trials could be initiated to verify whether this therapy would work for human hair regeneration.

HealthWatch:How to become a marrow donor

By Dr. Matthew Watson

COLUMBUS, Ga. --

Every year, thousands of people like Noah Hein are diagnosed with blood cancers such as leukemia. A bone marrow or cord blood transplant can save their lives. The patients who do not have a donor in their family, depend on the National Marrow Donor Program and its Be the Match Registry. At this donor drive in honor of Noah , Jimmy Dawes was the 100th person to walk in and join the registry.

I saw the story and read the story about Noah and it touched my heart personally because my father lost a battle with leukemia when I was 14 so it kind of hit home for me personally, says Dawes.

After filling out the paper work, you simply swab your cheeks. Doctors will be looking for a tissue match, specifically the human leukocyte antigen or HLA. HLAs are proteins, or markers found on most cells in your body.

Roderick Gunn works for the National Marrow Donor Program.

If your tissue type comes up as a match, you would then be asked to submit a blood sample, so we could do confirmatory testing to confirm that you are indeed the best possible match, says Gunn.

Then, after passing a physical exam,the transplant is scheduled. There are two ways to give. Peripheral blood stem cells or PBSC and marrow. Gunn says PBSC is used 80 percent of the time but the doctor chooses the best donation method for the patient. PBSC is similar to giving blood at a blood drive.

And they separate the stem cells from your blood while at the same time returning your blood back to you.

In marrow donation, the donor is anesthetized and a special needle is inserted into pelvic bone, and the marrow withdrawn.

Gunn says the program needs more minorities. He says its harder to match minority patients with donors because the pool is so small. He says often misinformation can keep people away from the program. One myth is its going to cost the donor too much money.

Fixing broken bones a growth industry

By LizaAVILA

Scientists have paved the way for human bones to be replaced with new ones grown outside the body. Photo: iStockphoto

SCIENTISTS have grown human bone from stem cells in a laboratory, paving the way for patients to have broken bones repaired - or even replaced with new ones grown outside the body from their own cells.

Researchers started with stem cells taken from fat tissue. It took about a month to grow them into sections of fully formed living bone up to several centimetres long.

The first trial in patients is on course for later this year, by an Israeli biotechnology company that has been working with academics on the technology.

Professor Avinoam Kadouri, head of the scientific advisory board for Bonus BioGroup, said: ''We use three-dimensional structures to fabricate the bone in the right shape and geometry. We can grow these bones outside the body and then transplant them to the patient.

''By scanning the damaged bone area, the implant should fit perfectly and merge with the surrounding tissue. There are no rejection problems as the cells come from the patient.''

The technology, developed with researchers at the Technion Institute of Research in Israel, uses three-dimensional scans of damaged bone to build a gel-like scaffold that matches the shape.

Stem cells, known as mesenchymal stem cells, that have the capacity to develop into many other types of body cell, are taken from a patient by liposuction and are then grown into living bone inside a ''bioreactor'' - a machine that provides the conditions to encourage the cells to develop into bone.

Animals have already successfully received bone transplants, but in the latest study, the scientists were able to insert almost 2.5 centimetres of laboratory-grown human bone into a rat's leg bone, where it successfully merged with the remaining animal bone.

Human bones grown from fat in laboratory

By JoanneRUSSELL25

"We use three dimensional structures to fabricate the bone in the right shape and geometry. We can grow these bones outside the body and then transplant it to the patient at the right time.

"By scanning the damaged bone area, the implant should fit perfectly and merge with the surrounding tissue. There are no problems with rejection as the cells come from the patient's own body."

The technology, which has been developed along with researchers at the Technion Institute of Research in Israel, uses three dimensional scans of the damaged bone to build a gel-like scaffold that matches the shape.

Stem cells, known as mesenchymal stem cells, which have the capacity to develop into many other types of cell in the body, are obtained from the patient's fat using liposuction.

These are then grown into living bone on the scaffold inside a "bioreactor" an automated machine that provides the right conditions to encourage the cells to develop into bone.

Already animals have successfully received bone transplants. The scientists were able to insert almost an inch of laboratory-grown human bone into the middle section of a rat's leg bone, where it successfully merged with the remaining animal bone.

The technique could ultimately allow doctors to replace bones that have been smashed in accidents, fill in defects where bone is missing such as cleft palate, or carry out reconstructive plastic surgery.

Professor Kadouri said work was also under way to grow the soft cartilage at the ends of bones, which is needed if entire bones are to be produced in a laboratory.

Bone grafts currently involve taking bits of bone from elsewhere in the patients body and transplanting them to the area which is damaged to encourage healing.

More than 250,000 bone grafts are performed in the UK each year, including repairs to damaged jaws and the replacement of bone lost in operations to remove tumours.

Obesity Causes Increased Risk of Kidney Cancer, Kidney Stones, and Stroke

By Dr. Matthew Watson

by: Steve G. Jones, Ed.S

Obesity is defined as a body mass index (BMI) of 30.0 or greater. BMI is a ratio determined by weight and height. With a large percentage of Americans classified as being obese, research is showing the effects extra weight and obesity have on a person's overall health. Recent studies show that obese people have an increased risk of developing common kidney cancer, kidney stones, and an increased risk of having a stroke.

A study involving 1,640 participants studied the effects of weight on kidney cancer. The average age of patients was 62 and all participants had kidney tumors. The study showed that patients with a BMI of 30 or higher were 48% more likely to develop clear-cell renal cell cancer (RCC). With every 1 point increase in BMI, obese patients increased their odds of getting kidney cancer by 4%.

Out of all the participants, 67% of the obese patients had kidney cancer compared to 57% of non-obese patients. Researchers do not know why there is a link between obesity and kidney cancer. Researchers are looking into a secondary link involving diabetes, hypertension, hormonal changes, and decreased immune function. Read more…

Business-friendly Changes Proposed for Revenue Sharing by Stem Cell Agency

By Dr. Matthew Watson


The $3 billion California stem cell
agency, which hopes to generate income for the state through the sale
of stem cell therapies, is moving to make its profit-sharing rules
more friendly to business.

The proposed changes will come up Monday morning before the Intellectual Property and Industry Subcommittee of the
CIRM governing board.
No stem cell research funded by CIRM
has yet been commercialized. Its intellectual property regulations,
which determine payback criteria, were developed shortly after CIRM
was created in 2004. Ed Penhoet, one of the founders of
Chiron and now a venture capitalist, chaired the panel that worked
out the rules. He has since left the CIRM board.
A CIRM staff memo described the payment
rules in the case of a "blockbuster" therapy as "uneven"
and "lumpy." The memo said they "could be a
disincentive for the engagement of industry." Other rules were described as creating
"administrative challenges and uncertainty." The proposed changes, the memo said,
would address those issues and ensure a "comparable economic
return to California."
Here are links to the specific changes
-- see here and here.
Public sites where interested parties
can take part in the discussion are located in San Francisco, La
Jolla, Los Angeles and Irvine. Specific addresses can be found on themeeting agenda.
The proposed changes must go before the
full governing board and then into the state's administrative law
process before taking full effect.

Business Success Rate at Stem Cell Agency: Zero in Latest Round After 14 Fail

By Dr. Matthew Watson


California biotech companies chalked up
a zero in the latest funding round by the state's $3 billion stem
cell agency, although 14 tried to run a gauntlet that industry has
complained about for years.

All $69 million in last month's
translational research round went to 21 academic and nonprofit insitutions. No business received an award. One firm, Eclipse
Therapeutics
of San Diego, appealed to the agency's governing board but was not successful despite having a higher scientific score
than at least two winners.
The miniscule amount of funding for
commercial enterprises – less than 4 percent of $1.4 billion handed
out so far – has been a matter of concern for some time for both
industry and some members of the CIRM governing board. Most
recently, industry executives complained at an April hearing of the
Institute of Medicine panel looking into CIRM's operations.
Even a 2010 review commissioned by CIRM said the agency needed to do
better by business.
The question of funding goes beyond a
simple matter of fairness or "good science," as CIRM
describes its funding goal. Without efforts by industry to turn
research into cures, CIRM will not be able to fulfill promises to
voters in 2004 when they approved creation of the stem cell agency.
CIRM last month approved a set of five-year goals that push more
aggressively for development of commercial products, but the goals
lacked such things as a financing round devoted solely to business
applicants.
In last month's translational round,
applicants went through a three-step process, which is conducted
primarily behind closed doors. First came what CIRM calls
pre-applications. Those were reviewed by CIRM staff with the help of
outside advisors if necessary. Applicants who cleared that hurdle were allowed to apply for the full, peer-reviewed round. During that
process, the CIRM Grants Working Group reviews applications,
makes decisions and sends them to the full CIRM board for
ratification and possible changes. The board almost never has
rejected a grant approved by reviewers. But the board has ultimate
authority and sometimes funds applications that reviewers have
rejected. The applicants' names are withheld from the board and the
public during the process, although some of the board discussion and
the final vote is conducted in public. CIRM does not release the
names of rejected applicants unless they appeal.
In the translational round, a total of 42
pre-applications out of 167 were approved by staff, according to
CIRM. Thirty-eight came from nonprofits and academics out of the 153
such institutions that applied. Four out of 14 business
pre-applications advanced to full applications but none made the
final cut. All of the winning applications were linked to
institutions that have representatives on the CIRM governing board.
Those representatives are not allowed to vote on or take part in
discussion involving applications to their institutions.
The primary decision tool used by the
grant review group is a scientific score. In last month's round,
scores of approved grants ranged from 88 to 53. However, eight grants
that were ranked above 53 were rejected by the board. One of those
higher-ranking applications came from San Diego's Eclipse
Therapeutics, which scored 58. The low-ranking grants were approved
for what CIRM describes as "programmatic" reasons.
More than three weeks ago, the
California Stem Cell Report asked CIRM for figures on the
numbers of applications in the translational round, including those
for business. CIRM said the figures had not been compiled and would
not be available until after the awards were made on May 24. The
numbers were finally supplied yesterday.
Our take: The number of applicants, and
their breakdown, is basic information that should be part of board's
decision-making process. The statistics should be routinely available
well in advance of the board's meeting. Indeed, the agency in its
earlier days used to routinely publish the figures. It may be now
that generating them is more time-consuming than necessary. The
recent performance evaluation of the agency said CIRM needs to make
major improvements in how it handles critical information needed for
its top management and board.
Whatever the reason, given CIRM's poor
track record with business, the agency's directors should diligently
track industry's success rate on applications. If proposals ranked as
low as 53 are approved while higher ranking applications from
business are bypassed, it warrants more than cursory examination.

‘Ugly’ Stem Cell Headlines and a Stem Cell Essay Contest

By Dr. Matthew Watson


California stem cell researcher Paul Knoepfler has been busy recently pumping out a plethora of items on his blog, including his own stem cell essay contest and a summary of "ugly" stem cell headlines.
He also rails, albeit briefly, against the Los Angeles Times "hate fest" against the California stem cell agency and offers some advice on developments involving prostate cancer, an affliction that he suffered from a few years ago.
Knoepfler, a UC Davis scientist, puts some cash on the line in his essay contest, with a prize of a $50 iTunes card plus publication of the winning piece. He is looking for a "convincing, non-fiction essay on stem cells thinking entirely outside the box." No more than 500 words. He has two categories, one for persons under 18 and one for persons over that age. June 30 is the deadline for submissions.
Knoepfler also wrote about Twitter and how it can be used by scientists in a useful item called "The scientist's top 10 guide to Twitter." We recommend it.

Two California Stem Cell Agency Directors Plump for Proposition 29

By Dr. Matthew Watson


Two directors of the $3 billion
California stem cell agency have popped up in the battle over the
anti-tobacco initiative on tomorrow's ballot in the Golden State.

They are Sherry Lansing and
Kristiina Vuori, who were the subjects of a column by Michael
Hiltzik
of the Los Angeles Times dealing with Proposition
29
, the "Son of CIRM" measure that would raise
$800 million for research by increasing the price of cigarettes by $1
a pack. In addition to serving on the CIRM board, Lansing heads her
own anti-cancer foundation and is chair of the board of the UC
regents. Vuori is head of the Sanford-Burnham Institute in La
Jolla.
Proposition 29 is patterned after the
measure that created the stem cell agency. The organization established by Proposition 29 would also be governed by a board that is run by
representatives of organizations almost certain to receive the bulk
of the funding, as is the case with CIRM.
In an op-ed piece on Friday, Lansing and
Vuori said the Times and Hiltzik had fallen for "a smokescreen"
put up by tobacco companies which are spending something in the
neighborhood of $40 million to defeat the initiative. Lansing and
Vuori said the measure is needed to stop smoking by young people as
well as providing cash for research for tobacco-related diseases.
Young people are more sensitive to price increases of cigarettes than
adults, according to research.
Lansing and Vuori referred to a column
in which Hiltzik opposed the measure because it would divert money
from more immediate state needs, including health and welfare
programs for children, education and the poor. (See here for thecolumn and here, here and here for related items.)
In his most recent column, Hiltzik
said,

"The...problem with Proposition 29
is its pigeonholing of the money for cancer research rather than for
immediate needs here in California that are absolutely dire. It’s
all well and good to say that cancer research benefits everyone, but
the real question is whether it should be the absolute top priority
for a state that can’t afford to keep its children fed or offer
them medical care in the here and now. 

"Lansing and Vuori say the fact
that Prop. 29 'fails to provide funding for schools, roads or
affordable housing' is irrelevant, because it was 'was never intended
to solve these problems.'

"In the context of the state’s
needs, this is a rather callous approach to take. Let’s spell out
why, so Lansing and Vuori won’t be so inclined to dismiss these
necessities of life so casually."

Hiltzik cited a list of state
government cuts that have meant the loss of health coverage for
400,000 California children, eliminated welfare benefits for 578,000
poor California families and would mean an end to state college
student aid for 72,000 young people from less affluent families.
Hiltzik continued,

"That’s just the beginning of
what might be cut because the state needs money—and won’t be able
to lay its hands on the hundreds of millions of dollars that Lansing,
Vuori, and their research colleagues are angling for. They don’t
want voters to be reminded that there are competing demands for the
tobacco money, and they do so by failing to mention that they exist,
and also by presenting the spending on cancer research as the voters’
only choice. 

"It’s the only choice because
the promoters of Proposition 29 designed it that way. Advocates of
programs like this love to pass them in via voter initiatives because
they leave no room to measure them against alternative needs."

 A final note: The New York Times
carried a piece yesterday on Proposition 29 that drew 481 comments.
The article said, 

"Organizers argued that the tax would have
less chance of passing if voters thought it would go into the state
coffers, and said that their only goal here was cutting down on
smoking."

 Also yesterday, Willie Brown, the former mayor
of San Francisco and a keen observer of California politics,
predicted voter approval of the measure along with an increase in
cigarette smuggling from adjacent states and the sale of discount
smokes at the 58 Indian casino sites in the state.

Bone Marrow Transplant Milestone

By raymumme

7 June 2012

Bone Marrow Transplant Milestone

Today is a big day for the Waikato Hospital Haematology Department and equally big for consultant haematologist Dr Humphrey Pullon who established the transplant service there 20 years ago.

The first autologous bone marrow transplant was carried out at Waikato Hospital on 25 June 1992 and was today celebrated with a patient afternoon tea, which about 120 transplant recipients attended.

By the end of the month we will have performed 317 transplants in 301 patients over the past 20 years, said Dr Pullon.

The first patient went down to Wellington to have her stem cells collected and they were then driven back up to be stored here She is still alive, but was unable to attend today.

We did the stem cell collection of the second patient, who is sadly no longer alive, and our third patient was cured of Lymphoma as a result of his transplant.

The third patient was Lloyd Given of Tauranga who attended todays afternoon tea.

I would like to extend my thanks to Waikato Hospital, Humphrey and the oncologist at the time, Grant Trotter, he said.

The autologous bone marrow transplant process is a long and involved one.The cancer patient is treated and goes into remission or gets to a point where the cancer is well controlled.

Gladstone Scientists Reprogram Skin Cells into Brain Cells

By Dr. Matthew Watson

By Anne Holden on June 7, 2012

Scientists at the UCSF-affiliated Gladstone Institutes have for the first time transformed skin cells with a single genetic factor into cells that develop on their own into an interconnected, functional network of brain cells.

The research offers new hope in the fight against many neurological conditions because scientists expect that such a transformation or reprogramming of cells may lead to better models for testing drugs for devastating neurodegenerative conditions such as Alzheimers disease.

Yadong Huang, MD, PhD

This research comes at a time of renewed focus on Alzheimers disease, which currently afflicts 5.4 million people in the United States alone a figure expected to nearly triple by 2050. Yet thereare no approved medications to prevent or reverse the progression of this debilitating disease.

In findings appearing online today in Cell Stem Cell, researchers in the laboratory of Gladstone Investigator Yadong Huang, MD, PhD, describe how they transferred a single gene called Sox2 into both mouse and human skin cells. Within days the skin cells transformed into early-stage brain stem cells, also called induced neural stem cells (iNSCs). These iNSCs began to self-renew, soon maturing into neurons capable of transmitting electrical signals. Within a month, the neurons had developed into neural networks.

Many drug candidates especially those developed for neurodegenerative diseases fail in clinical trials because current models dont accurately predict the drugs effects on the human brain, said Huang, who is also an associate professor of neurology at UCSF. Human neurons derived from reengineered skin cells could help assess the efficacy and safety of these drugs, thereby reducing risks and resources associated with human trials.

Huangs findings build on the work of other Gladstone scientists, starting with Gladstone Investigator, Shinya Yamanaka, MD, PhD. In 2007, Yamanaka used four genetic factors to turn adult human skin cells into cells that act like embryonic stem cells called induced pluripotent stem cells.

Also known as iPS cells, these cells can become virtually any cell type in the human body just like embryonic stem cells. Then last year, Gladstone Senior Investigator Sheng Ding, PhD, announced that he had used a combination of small molecules and genetic factors to transform skin cells directly into neural stem cells. Today, Huang takes a new tack by using one genetic factor Sox2 to directly reprogram one cell type into another without reverting to the pluripotent state.

Avoiding the pluripotent state as Drs. Ding and Huang have done is one approach to avoiding the potential danger that rogue iPS cells might develop into a tumor if used to replace or repair damaged organs or tissue.

Also known as iPS cells, these cells can become virtually any cell type in the human body just like embryonic stem cells. Then last year, Gladstone senior investigatorSheng Ding, PhD, announced that he had used a combination of small molecules and genetic factors to transform skin cellsdirectlyinto neural stem cells. Today, Huang takes a new tack by using one genetic factor Sox2 to directly reprogram one cell type into another without reverting to the pluripotent state.

Avoiding the pluripotent state as Drs. Ding and Huang have done is one approach to avoiding the potential danger that rogue iPS cells might develop into a tumor if used to replace or repair damaged organs or tissue.

We wanted to see whether these newly generated neurons could result in tumor growth after transplanting them into mouse brains, said Karen Ring, UCSF Biomedical Sciences graduate student and the papers lead author. Instead we saw the reprogrammed cells integrate into the mouses brain and not a single tumor developed.

This research has also revealed the precise role of Sox2 as a master regulator that controls the identity of neural stem cells. In the future, Huang and his team hope to identify similar regulators that guide the development of specific neural progenitors and subtypes of neurons in the brain.

Scientists Reprogram Skin Cells To Brain Cells

For the first time, scientists at Gladstone Institute have changed skin cells, imbued with a single genetic factor, into cells that can become a group of interconnecting, functional brain cells. The findings show that there may be options in combating neurological conditions. This transformation of cells would pave the way for better methods in testing drugs for neurodegenerative conditions like Alzheimers disease.

The research follows increased interest in Alzheimers disease. Currently, the disorder affects 4.5 million people in the U.S. and, by 2050, the number will have tripled. There are no medications to prevent or reverse Alzheimers Disease at this time.

The findings are published online at Cell Stem Cell and describe how the team of researchers transfer a single cell, known as Sox2, into mouse and human skin cells. Shortly, the skin cells became early-stage brain stem cells called induced neural stem cells (INSCs). The INSCs were able to self-renew and transmit electrical signals. The neurons were able to become neural networks within a month.

Many drug candidates especially those developed for neurodegenerative diseases fail in clinical trials because current models dont accurately predict the drugs effects on the human brain, commented Gladstone Investigation Dr. Yadong Huang, who is also an associate professor of neurology at the University of California, San Francisco (UCSF), in a prepared statement. Human neuronsderived from reengineered skin cellscould help assess the efficacy and safety of these drugs, thereby reducing risks and resources associated with human trials.

Huangs study was based off work done by Gladstone Investigator Dr. Shinya Yamanaka. Yanaka had four genetic factors become adult human skin cells then into embryonic stem cells, otherwise known as induced pluripotent stem cells (iPS cells). The cells can become almost any type of cell in the body. As well, last year, Gladstone Senior Investigator Dr. Sheng Ding found a combination of small molecules and genetic factors that could change skin cells into neural stem cells. These days, Huang uses one genetic factor, Sox2, to directly reprogram cell types without having to resort back to a pluripotent state.

We wanted to see whether these newly generated neurons could result in tumor growth after transplanting them into mouse brains, explained Karen Ring, UCSF Biomedical Sciences graduate student and the papers lead author, in the statement. Instead we saw the reprogrammed cells integrate into the mouses brainand not a single tumor developed.

The findings of the project have shown that Sox2 acts as a master regulator that maintains the identity of neural stem cells. In the future, Huang and his fellow researchers hope that they can identify similar regulators that can help the development of particular neural progenitors and subtypes of neurons in the brain.

If we can pinpoint which genes control the development of each neuron type, we can generate them in the petri dish from a single sample of human skin cells, noted Huang. We could then test drugs that affect different neuron typessuch as those involved in Parkinsons diseasehelping us to put drug development for neurodegenerative diseases on the fast track.
