Doris Tyler lay on the examining table as the doctor stuck a long, thin tube into her belly. The doctor pulled back a plunger, and the syringe quickly filled with yellow blobs tinged with pink.“Look at that beautiful fat coming out. Liquid gold!” one of the clinic’s staff exclaimed in a video of the procedure provided to The Washington Post.Hidden in that fat were stem cells with the amazing power to heal, the Stem Cell Center of Georgia had told Tyler. The clinic is one of hundreds that have popped up across the country, many offering treatments for conditions from Parkinson’s disease to autism to multiple sclerosis.Federal regulators have not approved any of their treatments, and critics call such clinics modern-day snake-oil salesmen. But on that day in 2016, Tyler trusted the clinic to extract stem cells from her fat and inject them into her eyes, where she was told they could halt or even cure the macular degeneration threatening her sight.Five days after … [Read more...] about Miracle cures or modern quackery?

ORLANDO, Fla.--(BUSINESS WIRE)--Apr 26, 2018--Hesperos, Inc. has increased its pioneering human-on-a-chip drug testing capabilities by adding a new in vitro, human-human neuromuscular model to its patented multi-organ microfluidic device systems. Abnormal function of the neuromuscular junction is associated with neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and spinal muscular atrophy, and a human model will be critical in developing and selecting effective drugs to treat these diseases.This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20180426006161/en/(Graphic: Business Wire)The breakthrough technology is described in a recent Biomaterials paper by Hesperos CSO James Hickman from the Hybrid Systems Laboratory at the University of Central Florida, “ Stem cell derived phenotypic human neuromuscular junction model for dose response evaluation of therapeutics.” The technology is licensed to … [Read more...] about Human-on-a-chip Company Hesperos Licenses First Functional Stem-Cell Derived Neuromuscular Junction Model
Donor age does not appear to influence the functionality of stem cells derived from adult body tissues, concludes a new review. The analysis of research on induced pluripotent stem cells (iPSCs) finds that not only are typical signs of aging reversed in iPSCs, but cells derived from both older and younger donors show the same ability to differentiate into mature body cells. This validates iPSCs as a viable alternative to embryonic stem cells in regenerative medicine. Published in Frontiers in Cardiovascular Medicine, the study highlights the enormous potential of iPSCs derived from elderly patients to treat their age-related diseases -- and indicates future areas of research for this relatively new field. "As average life expectancy continues to rise, so does the rate of age-related chronic and degenerative diseases," explains Dr. Nicolle Kränkel from Charité, a medical university in Germany. "Organ replacement and other cell-based treatments could increase … [Read more...] about Stem Cells From Adults Function Just as Well as Those From Embryos

N-Sky/Getty Images Strange creatures have emerged from Pablo Ross’s University of California, Davis lab. They’re neither strictly sheep nor fully human. Instead, they’re a bit of both. In a biotech breakthrough — the second of its kind in just over a year — Ross announced at the American Association for the Advancement of Science last week that he and his colleagues have successfully grown nonhuman animal embryos that contain human cells. Previously, the host species were pigs. Now, they’re sheep. They have the potential to revolutionize organ transplantation and help save thousands of lives. These human-animal hybrids, or interspecies chimeras, are not just the product of bizarre experimentation done for the sake of science. They have the potential to revolutionize organ transplantation and help save thousands of lives each year in America and around the globe. Though this breakthrough brings us one step closer to growing transplant organs inside … [Read more...] about Science of the Lambs: We can now grow human cells in sheep
