I’ve been blogging about stem cells now for about 8 years and the recent level of hype about and fluffy media coverage of Celularity, the biotech spun out of Celgene, ranks right up here with the most extreme past cases I’ve seen. What is Celularity and who is its leadership? It’s a new biotech focused on placental stem cells with some familiar, well-known leaders including Bob Hariri and Peter Diamandis, and famous tech names on their board including John Scully and Bill Maris, along …Read More

Stem cells for flu? For me, that idea is new. Some months back there was buzz about the stem cell biotech Longeveron related to its report on early trial data on testing infusions of mesenchymal stem cells for frailty in the aged. Frailty that pops up in some aging folks can manifest in a variety of ways and contribute both to reduced quality of life and mortality. This week a PR firm for Longeveron sent out an email suggesting that the company’s investigational stem …Read More

Imagine an old man and a teenager sitting side by side, with blood flowing from the kid to the oldster in a stab at anti-aging. Sort of like a one-way fountain of youth via blood flow…Sci-fi? People are kind of trying it in the real world. A self-described ‘clinical trial’ of a sort by a company called Ambrosia essentially lets you buy an infusion of a younger person’s blood in an attempt at anti-aging for $8,000. Interested? Reportedly tech guru Peter Thiel is: “I’m not convinced yet …Read More

Is there a stem cell connection between the brain and aging? Could a type of brain stem cell control whole body aging? A recent big Nature article from the lab of Dongcheng Cai argues an emphatic “Yes” to these questions, at least in mice. In the Zhang, et al paper, entitled “Hypothalamic stem cells control ageing speed partly through exosomal miRNAs”, their team reports the claim that a narrow population of hypothalamic stem cells are directly fighting aging of the entire murine body via a …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

A new Cell paper from Juan Carlos Izpisua Berlmonte’s group has made headlines about anti-aging across the globe because it suggests that the four core induced pluripotent stem cell (IPSC) factors use by Shinya Yamanaka to make IPSC can reverse aging. I’ve pasted the graphical abstract from the paper below and done a quick journal club style overview based on a quick skim of the paper. Some of the media headlines are rather dramatic on this story. For instance, in a story on it over at STAT …Read More
