Just one word placentas: Can Celularity live up to hype?

Celularity-e1519061558939

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 President’s Day: Dealing with Reality Trump is Threat to Science & Democracy

Trump-Liberty-Bell

On President’s Day, let’s think about our country’s leader, Donald Trump. Do we have to? Yeah, sometimes we do. For the first time in my lifetime, I see the President of the United States as a serious threat to overall science & to our country’s democracy. Trump is not well-acquainted with fact-based reality and that’s

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

Can you make a synthetic embryo, also called an embryo model? Developmental biologist Magdalena Zernicka-Goetz has long been on the trail of this seemingly almost uncatchable quarry. With her team’s publication in Science today they took a big step forward on this path even if some major hurdles remain. You can see her discussion of

UK should freeze mitochondrial replacement as Egli paper ID’s serious problem

Egli-genetic-drift-paper

An important new Cell Stem Cell paper from Dieter Egli’s lab points to an inherent, serious problem with so-called 3-person IVF or mitochondrial replacement technology that warrants putting an immediate hold on all efforts to use it in humans. I have pasted the graphical abstract from the paper below. For years a few of us scientists and

Obokata questioned by police over STAP cell fiasco

si-Haruko

Haruko Obokata was reportedly questioned by police in Japan today. The questioning relates to the STAP cell scandal that led to the retraction of two Nature papers. As first author of the papers, Obokata and other authors had reported that they could make IPSC-like cells simply via acid or other stress treatment. However, it is

Perspectives on Pedersen Lab Human-Mouse Chimera Paper

human-mouse-chimera

A new Cell Stem Cell paper by Victoria L. Mascetti and Roger Pedersen on human-mouse chimera modeling is quite interesting and important. I really enjoyed this short paper, but I do have a reservation about one way that it is being interpreted. The authors show that human pluripotent stem cells (hPSC) including induced pluripotent stem cells
