New lab-grown blastoids are strikingly similar to human embryos

blastoids nature paper figure 2

A new word has been added to the lexicon of human stem cell research – blastoids, aka “blastocyst-like structures.” Unlike the familiar three-layered embryo that emerges during the third week of prenatal development, the earlier blastocyst resembles a fluid-filled soccer ball, with a smear of cells on the interior face destined to develop into the […]

Fact check: Lung Health Institute & cell therapies for lung disease

the lung health institute

What should we make of clinics like the Lung Health Institute? These clinics sell unproven stem cell or regenerative therapies for lung disease. Overall, I’m extremely skeptical. I don’t believe it’s worth the cost. There are also going to be potentially serious health risks. Lung disease is a broad category including COPD, emphysema, pulmonary fibrosis,

How much does platelet rich plasma or PRP injection cost? Is it a good option?

prp cost polling data, platelet rich plasma

How much does platelet rich plasma or PRP injection cost? We might start by first talking about how to define PRP. PRP is an extract from blood enriched for platelet growth factors. There are many ways of making PRP and products are very heterogeneous. Some preps may contain actual platelets or fragments of platelets. These

What are induced pluripotent stem cells or IPS cells?

induced pluripotent stem cells clinical trials map

Induced pluripotent stem cells or iPS cells just might be the most exciting development in the stem cell field over the last 15 years. They have unique potential for clinical impact for regenerative medicine too. This may manifest both through their use to produce differentiated cellular therapies and indirectly via disease modeling as well as

What are totipotent stem cells & what can they do?

Multipotent & totipotent vs pluripotent stem cells, very early human embryos totipotent stem cells

Sometimes patients or my students ask me, “What are the best stem cells?” what information are they looking for? I think they often are looking for the most powerful stem cells so perhaps they should be asking, “What are totipotent stem cells?” Other times it seems what patients specifically want to know is what might

Jellyfish on the brain: a critical look at Prevagen

crystal jellyfish aequorea victoria, Prevagen

I’ve been asked many times over the years if stem cell injections at for-profit clinics can help brain function, but recently the more common query is whether brain supplements such as Prevagen actually work. I’m skeptical of both unproven stem cell injections and supplements that are supposed to somehow help the brain, but some of
