As exosome work advances, clinics pitch unproven therapies to patients

exosome-clinical-trials

Time to sell exosome therapies to patients? No. Some stem cell clinics and related firms are looking for new ways to make profits and toward that goal a few have latched onto the legitimate buzz around exosome research. What are exosomes? Imagine if you could bubble up a pea-sized sphere off your skin full of

Why Mitalipov’s ‘magic’ room for human embryo CRISPR may give us pause

Shoukhrat-Mitalipov

The debate over whether the main conclusions of the Nature paper on human embryo CRISPR led by Shoukhrat Mitalipov’s lab at Oregon Health Sciences University (OHSU) are correct remains unresolved. Note that Nature just added an editorial alert just above the references section to their paper: “Updated online 02 October 2017. Editorial Note: Readers are alerted that some

CRISPR, human genetic modification, & a needed course correction

coverGMO-e1498086048321

Are designer babies made using CRISPR or other genetic modification technologies closer to reality today? If so, what exactly should we do about it? Researchers can use CRISPR to genetically modify just about any organism or its cells, but targeting humans is the subject of the most intense discussion including using CRISPR in the human germline

Paper on 1st use of CRISPR in normal human embryos: problems remain

CRISPR-human-embryo-Tang-et-al

The first report of the use of CRISPR gene editing in normal human embryos was published today as a short paper from a team in China. There have been rumors for over a year that more CRISPR human embryo papers were coming including some using normal embryos. Here’s one and we can now expect more even

Grading my stem cell predictions for 2016: how’d I do?

stem-cell-predictions

Below are the 2016 stem cell predictions I made last year and their status now color-coded near year’s end. Green is right, orange is mixed bag, and red is flat out wrong. Overall, I did better than most past years with only having entirely blown it on four. Stay tuned later this week for my 2017 predictions,
