Attendees at a fundraiser for Parkinson's patients enjoy food and the setting sun at the home of Jeffrey Strauss, owner of the Pamplemousse Grill. The proceeds help Summit4StemCell.org.

A bold experiment to relieve Parkinson's disease symptoms for many years faces a Nov. 4 deadline to raise a total of $2.5 million. That money will allow the group running the project to get matching funds from California's stem cell agency.

Thanks to the owner/chef of Pamplemousse Grill and a number of donors, the group just took a giant step toward that goal.

The group, Summit4StemCell.org, has been holding events for years to raise money to research the therapy, which will use skin cells from eight patients to form new brain cells. The cells will be implanted in the patients' brains to replace the cells destroyed in Parkinson's that make the neurotransmitter dopamine.

Supporters and some patients have climbed atop Mt. Kilimanjaro in Africa and to Base Camp at Mt. Everest, as well as holding local fundraisers. That money has advanced the research so it's feasible to try it in the patients. But more money is needed to pay for the treatment and related expenses.

So last week, supporters gathered at the home of Jeffrey Strauss, owner of Pamplemousse Grille in Solana Beach.

Proceeds from the $500-a-plate dinner brought in nearly $1 million for the project, said Sherrie Gould, an organizer and project sparkplug. Gould, a nurse practitioner at Scripps Clinic, interfaces between the clinical side, led by neurologist Melissa Houser of Scripps Clinic, and the research side, led by Jeanne Loring, a stem cell scientist at The Scripps Research Institute, and Andres Bratt-Leal of the Parkinsons Association of San Diego. The association is the nonprofit under which Summit4StemCell is held.

"Jeffrey is very close to a couple of our patients, and he literally opened up his home to about 130 people, completely provided food, drink, open bar, wine, wait staff, linens..." Gould said.

Counting in-kind donations, the total raised so far is about $1.5 million, meaning that Summit4StemCell needs to raise another $1 million by September, for a total of $2.5 million, Gould said. With that amount, the group can apply for $2.5 million in matching funds from the California Institute for Regenerative Medicine.

"Funding our mission has been at a grass-roots level, philanthropy, and a few minor grants," the project said in a fundraising email. "With over 900 people donating to the project we have been able to successfully biopsy the patients skin and create dopamine-producing neurons from eight of Dr. Houser's PD patients. We are now comparing cell lines with other researchers' lines, characterizing/purifying the cells, and most exciting: testing the neurons from our patients in an animal model of PD."

The ability to reliably and safely make in the laboratory all of the different types of cells in human blood is one key step closer to reality.

Writing today in the journal Nature Communications, a group led by University of Wisconsin-Madison stem cell researcher Igor Slukvin reports the discovery of two genetic programs responsible for taking blank-slate stem cells and turning them into both red and the array of white cells that make up human blood.

The research is important because it identifies how nature itself makes blood products at the earliest stages of development. The discovery gives scientists the tools to make the cells themselves, investigate how blood cells develop and produce clinically relevant blood products.

This is the first demonstration of the production of different kinds of cells from human pluripotent stem cells using transcription factors, explains Slukvin, referencing the proteins that bind to DNA and control the flow of genetic information, which ultimately determines the developmental fate of undifferentiated stem cells.

During development, blood cells emerge in the aorta, a major blood vessel in the embryo. There, blood cells, including hematopoietic stem cells, are generated by budding from a unique population of what scientists call hemogenic endothelial cells. The new report identifies two distinct groups of transcription factors that can directly convert human stem cells into the hemogenic endothelial cells, which subsequently develop into various types of blood cells.

The factors identified by Slukvins group were capable of making the range of human blood cells, including white blood cells, red blood cells and megakaryocytes, commonly used blood products.

By overexpressing just two transcription factors, we can, in the laboratory dish, reproduce the sequence of events we see in the embryo where blood is made, says Slukvin of the Department of Pathology and Laboratory Medicine in the UW School of Medicine and Public Health and the Wisconsin National Primate Research Center.

The method developed by Slukvins group was shown to produce blood cells in abundance. For every million stem cells, the researchers were able to produce 30 million blood cells.
