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

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
New lab-grown blastoids are strikingly similar to human embryos Read More »
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

Organoids and especially brain organoids, which are made from pluripotent stem cells, are one of the most interesting developmental biology technologies of the last half a dozen or so years. Still some folks can’t help but get carried away when thinking about brain organoids it seems. A new Science paper from a team led by

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

When my wife and I were expecting our first daughter way back in the nineties, we received a paper pamphlet about cord blood banking. Back then, I was a graduate student at UC San Diego School of Medicine working toward my Ph.D. in Molecular Pathology and my wife was in medical school at the time

Sometimes on The Niche or while teaching students as a professor here at UC Davis School of Medicine, I’ve been asked: What is a teratoma? Not all tumors are created equal and some like teratomas are particularly unusual. Exactly what is a teratoma tumor? Teratomas are germ cell tumors. What this means is that the
