Can Hearts Repair Themselves Via Stem Cells

heart-stem-cells1

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 …

Weekly reads: embryo pubs stir things up, organoids crying, & more

organoids tear glands sm

This was an unusual week in that three papers in a sense collided together related to embryo production and growth, raising new research possibilities but also serious ethical questions. New research: what is an embryo & what is not? The first two Nature papers reported generating the most realistic models of human embryos from scratch …

Some stem cell good news, stuff for debate, & cool pubs

sep6_2016_salkinst_epithelialinvivoregeneration1822142291-1

Sometimes we could all use a jolt of good news and cool science. Those of us in the stem cell field probably get tired at times of all the bad-ish, even if important news (like this from Michael Hiltzik of the LA Times) out there surrounding certain unproven stem cell offerings and also clinics that …

Anti-aging and the billionaires young blood & stem cell club

Old-man-getting-young-bloodSeason-4-episode-5-of-Silicon-Valley-22Blood-Boy22, stem cells anti-aging

What is the Billionaire’s blood & stem cell club and how does one get into that? The focus of what I’m satirically calling this “billionaire’s club” is on anti-aging and prolonging life. If you have a lot of money and are willing to take risks on yourself toward some specific goal such as staying young …

Perspectives on uncritical NYT coverage of cardiac mitochondrial transplant trial

mitochondrial-transplant-for-heart

One of the reasons I’m a scientist is that I find biology fascinating and admittedly novel biomedical science can really catch my eye, but more recently as a somewhat grizzled researcher, I’ve become increasingly skeptical about some “sexy” research and media coverage of it. A small red flag went up for me as I was …

Japan stem cell oversight system too lax?

HeartSheet-Japan-system-stem-cell-oversight

The Japan stem cell and regenerative medicine oversight system has been designed to move investigational therapies forward fast, much faster than the systems in other countries such as the U.S. But how well is it working so far? It’s an important question both for that country and more globally as the Japanese system was touted …

Japan conditionally approves new IPS cell-based heart study

Yoshiki-Sawa-IPS-cells-stem-cells-heart-diseease

Where do things stand with IPS cell translational research? The newest development is that regulators in Japan just have given conditional approval to an Osaka University team to an induced pluripotent stem (IPS) cell-based study for ischemic heart disease. For years IPS cell-based products have been on-again off-again in active clinical study for macular degeneration, work …

Stem Cells on Valentine’s Day: Cardiac Regenerative Medicine

heart-stem-cells1

Can stem cells mend a broken heart via cardiac regenerative medicine? The idea of the use of stem cells and regenerative medicine strategies for heart disease has taken us on a roller coaster ride over the years. There are many controversial questions still such as whether the adult heart has meaningful populations of endogenous stem …
