ACT’s Top Scientist Sells $1.5 Million in Company Stock

Posted: February 19, 2012 at 4:59 pm


The mainstream media waxed enthusiastic last month when a California hESC clinical trial reported positive results dealing with blindness.

The report was first published account of a human trial of embryonic stem cell based therapy and involved Advanced Cell Technology, which is headquartered in Santa Monica, Ca. Despite a glowing reception of the trial's results, the firm is years away from being able to market the therapy at a profit – if it ever can do so.

The firm's chief scientific officer, Robert Lanza, moved quickly, however, to capture some monetary gain from the news, which was announced in a press release Jan. 23 by ACT.

On Jan. 23 and 24, Lanza sold 7.7 million shares in ACT for $1.5 million, according to SEC documents. He sold the stock at 18 and 19 cents a share. That compares to an ACT price of about 8 cents at the end of 2011. Lanza still holds 26 million shares in the firm. The acquisition price of the stocks is unknown.

There is nothing to suggest anything untoward about Lanza's sale. But it is a reminder that creating a successful stem cell therapy is about making money. Without a profit, there will be no therapy, as Geron reminded everyone last November when it dropped its longstanding hESC trial.

The California Stem Cell Report has asked Lanza if he has any comments about the sale of the stock. We will carry his remarks verbatim when we receive them.

The Seeking Alpha web site appears to have been the first to report the sale. Here is their complete item.

"Advanced Cell Technology, Inc. (ACTC.OB): ACTC is a development-stage biotech focused on the development and commercialization of human embryonic and adult stem cell technology in the field of regenerative medicine. On Wednesday, Chief Science Officer Robert Lanza filed SEC Form 4 indicating that he sold 7.7 million shares for $1.5 million, ending with 26.0 million shares after that sale. ACTC shares have rallied strongly since the beginning of the year, up from 8.2 cents at the end of last year to currently in 14-15c range after rising above 20c just earlier this week."

CIRM Contracting: $1.3 Million for IT, $887,282 for Legal

Posted: February 19, 2012 at 4:59 pm


The California stem cell agency this week performed its semi-annual public disclosure of its contracts with outside firms, the second largest item in its operational budget of $18.5 million.

The contracts are scheduled to run about $3.3 million this fiscal year, according to the budget approved last May. That figure is up about 18 percent from the previous year.

According to the contract information posted this week, the two largest contracting expenditures this year are for information technology work, including the ongoing struggles with the grants management system – $1.3 million – and legal help – $887,282. The figures were compiled by the California Stem Cell Report. CIRM did not provide totals.

Outside contracts are second to the cost of salaries and benefits at the agency. One reason for the size of the contracting expense is the small size of the CIRM staff, which is now about 50.

The contracting information will be presented to the CIRM directors' Governance Subcommittee next Friday. The committee is being asked to approve an increase in the contract with Kutir Corp., from $250,000 to $470,000. By the end of 2011, CIRM had already paid out $219,680 to Kutir. The firm provides software development services.

Infonetica, which provides technology advice, would also see an increase from $236,060 to $300,000, under the staff proposal.

A staff memo to the board said,

"(Kutir's) services are key as CIRM continues to progress in automating its grants management systems to meet the requirements of both new RFAs as well as ongoing reporting obligations.""

The public can participate in the Governance meeting at locations in San Francisco, Sacramento, Irvine, Los Angeles, South San Francisco and La Jolla. Specific addresses can be found on the agenda.

Stem Cell Agency on Bee Article and Voter Expectations

Posted: February 19, 2012 at 4:59 pm


The California stem cell agency today said the seven-year-old "audacious vision" of voters when they created the $3 billion research effort "is still possible."

The comment was made in an item on the agency's blog by Amy Adams, the agency's communications manager.

Her entry point was an opinion piece in The Sacramento Bee on Sunday exploring some of the ins and outs of the agency. Among other things, CIRM President Alan Trounson was quoted by writer David Lesher as "optimistically" predicting successful California stem cell treatments in five years.

Adams wrote,

"Lesher makes clear that there are many challenges ahead in bringing new therapies to patients: he said of the voters who created CIRM, 'It was pretty audacious of them in 2004 to try to create another economic driver like Silicon Valley and save lives at the same time.'

"And while the vote was audacious, we agree with his conclusion that despite risks and challenges that vision is still possible."

Blue-Ribbon Panel Seeks Public Comment on California Stem Cell Agency

Posted: February 19, 2012 at 4:59 pm


The California public is being given a chance to weigh in with anonymous comments about what they think of the performance of the $3 billion California stem cell agency.

Their opinions are being sought by a blue-ribbon, Institute of Medicine panel. The IOM is being paid $700,000 by the agency to examine its operations.

The questions include the importance of stem cell research and CIRM's role, its openness and transparency, an assessment of its grant programs and how it should share information with the public, suggestions for improvements and more.

The online form was posted recently on the IOM web site and can be found here. The deadline for submissions is March 19.

The IOM also has survey forms for academic and non-profit CIRM grant recipients, CIRM grant recipients that are businesses(which the IOM calls "industry partners") and "leadership of CIRM-funded institutions." The deadline for those is March 19 as well.

Stem cells used to increase bone strength

Posted: February 19, 2012 at 9:20 am

A research team led by UC Davis Health System scientists has developed a novel technique to enhance bone growth by using a molecule which, when injected into the bloodstream, directs the body's stem cells to travel to the surface of bones.

Once these cells are guided to the bone surface by this molecule, the stem cells differentiate into bone-forming cells and synthesize proteins to enhance bone growth. The study, which was published online today in Nature Medicine, used a mouse model of osteoporosis to demonstrate a unique treatment approach that increases bone density and prevents bone loss associated with aging and estrogen deficiency.

"There are many stem cells, even in elderly people, but they do not readily migrate to bone," said Wei Yao, the principal investigator and lead author of the study. "Finding a molecule that attaches to stem cells and guides them to the targets we need is a real breakthrough."

Researchers are exploring stem cells as possible treatments for a wide variety of conditions and injuries, ranging from peripheral artery disease and macular degeneration to blood disorders, skin wounds and diseased organs. Directing stem cells to travel and adhere to the surface of bone for bone formation has been among the elusive goals in regenerative medicine.

The researchers made use of a unique hybrid molecule, LLP2A-alendronate, developed by a research team led by Kit Lam, professor and chair of the UC Davis Department of

Biochemistry and Molecular Medicine. The researchers' hybrid molecule consists of two parts: the LLP2A part that attaches to mesenchymal stem cells in the bone marrow, and a second part that consists of the bone-homing drug alendronate. After the hybrid molecule was injected into the bloodstream, it picked up mesenchymal stem cells in the bone marrow and directed those cells to the surfaces of bone, where the stem cells carried out their natural bone-formation and repair functions.

"Our study confirms that stem-cell-binding molecules can be exploited to direct stem cells to therapeutic sites inside an animal," said Lam, who also is an author of the article. "It represents a very important step in making this type of stem cell therapy a reality."

Discovery that migrating cells ‘turn right’ has implications for engineering tissues, organs

Posted: February 18, 2012 at 7:24 am

A UCLA research team discovered that migrating cells prefer to turn right when encountering changes in their environment. The researchers were then able to translate what was happening in the cells to recreate this left–right asymmetry on a tissue level. Such asymmetry is important in creating differences between the right and left sides of structures like the brain and the hand.

The research, a collaboration between the David Geffen School of Medicine at UCLA and the Center for Cell Control at UCLA's Henry Samueli School of Engineering and Applied Science, appears in the Feb. 17 issue of the journal Circulation Research.

"Our findings suggest a mechanism and design principle for the engineering of tissue," said senior author Dr. Linda L. Demer, a professor of medicine, physiology and bioengineering and executive vice chair of the department of medicine at the Geffen School of Medicine. "Tissue and organs are not simply collections of cells but require careful architecture and design to function normally. Our findings help explain how cells can distinguish and develop highly specific left–right asymmetry, which is an important foundation in tissue and organ creation."

Using microtechnology, the team engineered a culture surface in the lab with alternating strips of protein substrates that were cell-adhesive or cell-repellent, analogous to a floor with narrow horizontal stripes of alternating carpet and tile. Cells may encounter such surface changes when they travel through the body.

The researchers observed that as the migrating cells crossed the interface between "carpet" and "tile" sections, they exhibited a significant tendency to turn right by 20 degrees, and, like a marching band, lined up in long, parallel rows, producing diagonal stripes over the entire surface.

"We had been noticing how these vascular cells would spontaneously form structures in cultures and wanted to study the process," said first author Ting-Hsuan Chen, a graduate student researcher in the department of mechanical and aerospace engineering at UCLA Engineering. "We had no idea our substrates would trigger the left–right asymmetry that we observed in the cells. It was completely unexpected.

"We found that cells demonstrated the ability to distinguish right from left and to self-organize in response to mechanical changes in the surfaces that they encounter. This provides insight into how to communicate with cells in their language and how to begin to instruct them to produce tissue-like architecture."

According to the researchers, the cells can sense the substrates beneath them, and this influences the direction of their migration and what shapes they form in the body. Of most interest, the researchers said, was the fact that the cells responded to the horizontal stripes by reorganizing themselves into diagonal stripes.

The team hopes to harness this phenomenon to use substrate interfaces to communicate with cells and instruct them to produce desired tissue structures for replacement. By adjusting the substrates, the researchers say, they have the potential to guide what structures the cells and tissue form.

The next stage of the research will be to control and guide cells to self-organize into two-dimensional and, eventually, three-dimensional patterns chosen by the researchers.

According to the research team, this is one of the first studies to demonstrate that encountering a change in substrate can trigger a cell's preference for turning left or right. It is also one of the first studies showing that cells can integrate left–right asymmetry into a patterned structure of parallel diagonal stripes resembling tissue architecture.

"Applications for this research may help in future engineering of organs from a patient's own stem cells," Demer said. "This would be especially important given the limited supply of donor organs for transplant and problems with immune rejection."
