Can hearts repair themselves via their own stem cells? Science evolves Sometimes what we scientists all know to be true turns out later on to be wrong and there are clear instances of this in the stem cell field. For example for decades the dogma was that the adult mammalian brain did not have stem cells, but now most researchers believe that the adult brain does have stem cells, although for humans this is still being debated. What we perceive as factual can change over time. Yamanaka …Read More

IPS cell research is a growing area of promise for regenerative medicine. These stem cells, also known as iPSCs or more formally as Induced Pluripotent Stem Cells, are engineered cells that are programmed to function the same way as embryonic stem cells. They can be differentiated into possibly any type of cell that is needed for therapeutic purposes. Since iPSC production was first reported by Shinya Yamanaka using mouse and human cells in 2006 and 2007, respectively, cells from a whole host of species have …Read More

What’s been going on in the stem cell and regenerative medicine field over the past week and what are some worthwhile things to read? Today’s post has recommended recent reads from the scientific literature and the media. I’ve also got our weekly stem cell/regenerative medicine quiz question and the answer to last week’s. You can check out last week’s recommended reads here, which has last week’s quiz question. Toward the bottom of the post there’s also a “blast from the past” link to a piece …Read More

A researcher working at Kyoto University has reportedly engaged in misconduct leading to an institutional request for retraction of a paper from the journal Stem Cell Reports. The paper in question appears to have rather large-scale problems: “Kohei Yamamizu, a specially appointed assistant professor at the university’s Center for iPS Cell Research and Application, falsified all six main figures in the paper that claimed he had succeeded in generating a brain structure in vitro using iPS cells, according to Kyoto University.” The Center for iPS Cell …Read More

By Jeanne Loring There are ten million people in the world who have Parkinson’s disease. 125,000 of these are living in California.  People with the disease often have to step away from their jobs because the main symptoms – tremor or freezing up of muscles – make it difficult to get through a whole day of work. Parkinson’s disease is caused by the loss of a specific neuron type in the brain.  The dopamine neurons in the region of the brain called the substantia …Read More

By Agnes Soos Amid the hustle and bustle of downtown Boston, nearly four thousand researchers and exhibitors gathered for the 15th Annual ISSCR Meeting. With presentations from over thirty plenary lectures, and dozens of others featured in concurrent sessions and the daily Innovation Showcases, there definitely was no shortage of exciting research to discover and discuss. There was a record number of exhibitors this year with over 150 companies set up in Exhibit Hall. Added to this, the always-busy Meet-Up Hubs, the job boards …Read More

Where is the field of IPS cells going and how will this impact the overall field of stem cell-based regenerative medicine? Nobel Laureate Shinya Yamanaka, the discoverer of IPS cells, gave a really interesting recent interview to Nikkei that provides some fascinating insights into the future of this exciting technology that is now more than a decade old. For simplicity I have indicated top highlights from the Yamanaka interview below as bullet points. More IPS cell trials are on track to start as soon as 2018 …Read More

Ring the bell for a stem cell milestone. There’s been a whole lot of commotion about the NEJM article yesterday documenting the experiences of three women with macular degeneration who were blinded by non-FDA approved stem cell eye injections of fat stem cells at a business in Florida, but in the same issue of the journal there also was some encouraging stem cell news that came in the form of essentially a mirror image of the bad news paper. We can call it the “stem cell …Read More

By Samantha Yammine, PhD Candidate in Derek van der Kooy’s lab at the University of Toronto. See tweets live from #TMM2016 via @SamanthaZY here. Last week, 430 Canadian scientists, trainees, industry professionals, science communicators and international guests gathered in the picturesque ski town of Whistler, British Columbia for the annual Till & McCulloch meeting (TMM). This is Canada’s premier conference for stem cell research, which is co-hosted by the Centre for Commercialization of Regenerative Medicine, the Stem Cell Network, and the Ontario Institute for …Read More

Has it really been 10 years since induced pluripotent stem cells (aka IPS cells or IPSC) came onto the scene in the stem cell field? Yes, it was a decade ago that now Nobel Laureate Shinya Yamanaka (山中伸弥) published that seminal Cell paper on reprogramming to make mouse IPS cells and then human IPS cells came the next year. From the moment I read that first mouse IPS cell paper, I was very excited about the science and the ideas in it. The domain …Read More
