Interview with Bob Lanza on new ACT MSCs for MS paper

I did a brief email Q&A interview with Dr. Bob Lanza of Advanced Cell Technology (ACT) on their new hES MSCs pre-clinical data for Multiple Sclerosis. I discussed the paper itself in a concise review yesterday here. Thanks to Dr. Lanza for doing the interview. 1. Were you surprised at the fact that the therapeutic …

Jury is still out on purported adult pluripotent stem cells despite new MUSE paper

MUSE-cells

Are MUSE cells for real? Stem cells come in different types that vary in a key property called “potency”, but very few are pluripotent. The more potency, the greater the flexibility of a stem cell to make other cell types. Flexibility in the cellular world is power. The most powerful stem cells generally used are …

Occasionally I call out a particularly important comment by a reader on a major issue and today it is commenter Natalie DeWitt (see my earlier interview with her about her experiences at Nature’s The Niche) who has contributed a particularly insightful, knowledgable comment on my recent perspective piece the Cell cloning paper mishap. Many in the …

Analysis: what does the federal court embryonic ruling really mean & what’s next?

Knoepfler lab stem cells

Today the US Federal Court of Appeals via a 3-judge panel ruled in favor of continued NIH funding of human embryonic stem cell research (hESCR). The ruling is a setback for pro-life extremists trying to shut down a very promising avenue of stem cell-based regenerative medicine with their lawsuit. It’s a good day for the …

The stem cell gestalt of Geron Goodbye and the future of ACT

Geron-300x2212

Last year one of the biggest events in the stem cell field was biotech Geron punting its embryonic stem cell (ESC) program. Much consternation followed. Some folks opposed to ESCs happily pronounced ESC research dead. Some folks in favor of ESC thought the world was ending a year early. Others tried to look on the …

Obama giving up on embryonic stem cell research?

Obama1

Is Obama bailing out on support for embryonic stem cell research (ESCR)? As even casual readers of this blog easily surmise, I am a supporter of President Obama. I believe he has done a good job in his first term and deserves re-election. I also believe Romney would not be a good president, particularly as …

Witherspoon Council, Komen, and Fox News

They say politics makes strange bedfellows….remember the Witherspoon Council? These are the fellows who are the BFFs of the two scientists suing to stop federal funding of human embryonic stem cell (hESC) research. They also wrote a large, very stodgy tome about stem cell research, in which they mentioned me and this blog…kinda implying we …

Secrets of the Witherspoon Gang

What’s the Witherspoon Institute? Most of you know about the 2 scientists who for their own reasons want to kill embryonic stem cell (ESC) research and with it the hopes for millions of people. Relatively new on most of our radar screens, however, is an extremist right-wing “think tank” called The Witherspoon Institute, which I …

Key points about adult versus embryonic stem cells

Knoepfler lab stem cells

What with the Mississippi “personhood” amendment up for a vote today and also the Vatican Adult Stem Cell Conference beginning tomorrow, I thought today was a good time for a post about adult versus embryonic stem cells. Does stem cell research have to be either/or? Adult or stem? Can’t someone be for both adult and …

Why Horton was wrong: a person is not a person no matter how small, even in Mississippi

Horton-Hears-a-Who-in-Mississippi

Tomorrow night voters in Mississippi will vote on the so-called “Personhood Amendment”. If passed, the amendment would make a fertilized egg by definition a human being with the same rights as a living, breathing, thinking, walking person in the state of Mississippi. The consequences are not clear, but possibilities include such things as complete bans on …
