Call for 31 Anversa retractions by Harvard; heart stem cell concept broken?

heart-stem-cells1

In a stunner, Harvard and Brigham & Women’s Hospital reportedly have jointly called for the retraction of 31 papers on heart stem cell research authored by embattled heart stem cell researcher Piero Anversa. The scoop on this by STAT/Retraction Watch written by Ivan Oransky and Adam Marcus gives further details on this mess and past …

Aging: can we grow new brain cells as adults?

Cell-Stem-Cell-Boldrini-et-al.-new-brain-cells

Can we humans grow healthy new brain cells as adults and during later aging? The answer to this question is a big deal because it could have major impact on aging. Those hoped-for new brain cells could keep our brains functionally younger. Who doesn’t want to slow down the aging of their brain, right? Slowing …

Review of Nature paper: stem cell exosomes on the brain and aging

mouse-hypothalamus-brain-and-aging

Is there a stem cell connection between the brain and aging? Could a type of brain stem cell or the exosomes it secretes 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 …

Bioquark “reawaken” the dead with stem cells plan just zombie fodder?

Bioquark-e1496869311976

A company called Bioquark reportedly claims it intends to bring back the dead, as in deceased people or at least brain dead people, with stem cells. Or at least awaken their brains. If it works, would those people be like zombies? Is it ethical to experiment in this way on dead people? We first met …

Beyond zombies: reviving dead people with stem cells & lasers?

Bioquark-e1496869311976

There’s been a lot of buzz the last few days about reviving the dead  via stem cells. Is this possible? Who knows, but it would be very long odds. Could it lead to zombies? Not really, but there could be negative outcomes even if it seems to sorta work (more below). Bioquark, Inc. is a …

If I only had a brain: brain organoids from pluripotent stem cells

In a first for the field, scientists have used human pluripotent stem cells to grow miniature brain-like structures (brain organoids) in a dish in a lab (see beautiful image of one of these “mini-brains” at left from the paper). This exciting, pioneering feat, accomplished by a team from the Austrian Academy of Science in Vienna …

Stem cells on the brain: why can’t the brain just fix itself?

p27-staining-of-developing-mouse-brain-cerebellum.

Why doesn’t the brain fix itself using stem cells the way other organs do? Earlier this week I was lecturing to students here at UC Davis on stem cells. One of the points I raised was that most if not all of our organs have a compliment of stem cells that are there to maintain …
