Risks rise as ISSCR drops strict 14-day rule on human embryo growth in the lab

mouse embryos grown outside the lab

Something called the 14-day rule on growing human embryos in the lab helped keep a tough question in check for a long time: when is it ethically wrong or just practically unwise to continue growing a human embryo for research? There is no good answer based on science or anything else. ISSCR moves beyond strict

When does a human embryo model become the real thing & other tough questions for a new field

human embryo model mukul tewary sm

A human embryo model is a laboratory-produced collection of living cells that has some key things in common with real human embryos. They are made from pluripotent stem cells, which include embryonic stem cells and induced pluripotent stem cells or iPS cells. This research is both exciting and ethically complicated, raising some difficult questions. Embryo

As Neuroskeptic blog ends, reflections on skeptical science blogging

skeptic magazine science blogging

It seems like being somewhat skeptical would be an inherent part of being a biomedical scientist. But not always it seems. On the other hand, some of us take it to another level by science blogging out our skepticism about certain topics. Note that there’s something called the Skeptics Society that publishes a magazine Skeptic.

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,

Regenerative reads: brain organoids, Clinicaltrials.gov change

brain organoids sm

Sometimes change takes a very long time, but with brain organoids or advocating for better information for patients at Clinicaltrials.gov, after waiting you can see some interesting developments.  These are two of the regenerative medicine stories of the week, along with some striking research papers. Clinicaltrials.gov Some of us have been advocating for improvements at

Fact-check: F grade for irresponsible stem cell COVID-19 cure piece

vitro biopharma stem cells covid 19

At times there’s been seriously bad journalism covering COVID-19 itself including implications of various things being a COVID cure. Of course, media coverage of stem cell research itself sometimes ends up being a train-wreck of hype too. More recently we’ve seen irresponsible journalism also around the specific idea of stem cells for COVID-19, but sometimes

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
