![]() And actually, if you ever hear anyone talking about embryonic stem cells, these are the ones they're referring to, these ICM stem cells. So, it's kind of incredible to think that every single cell in your body can trace its ancestry back to this little group of stem cells, here. These inner cell mass pluripotent stem cells can differentiate into any of the more thanĢ00 different cell types in the adult human body when Pluri meaning several and potent referring to these stem cells' ability to actually do this differentiation. And what they can do as stem cells is they can specialize into Little bunch of cells that go on to become the embryo. This little grouping of cells down in here, referred toĪs the inner cell mass. ![]() And here, things start to getĪ little bit more interesting. The blastocyst stage, this hollow ball of cells So, the zygote starts to divide, right, by mitosis until it reaches When sperm and egg fuse because that's really where our stem cell story kinda begins. And let's actually startīack at the zygote, here, the cell that results So, let me show you what I mean by that over the course of this video. You got more and more committed down a certain pathway, and the decisions that you made moved you further and furtherĪlong this pathway, right? Well, it turns out that stemĬells operate in a similar way, going from unspecialized You had the potential to specialize into all sorts of different careers, and as you got a bit older, You could decide to be a pilot, or a doctor, or a journalist. When you were still anĪdorable little baby, you were just bursting with potential. "And I am worried about any moves that would slow further discovery - because we're still in the middle of this pandemic."ĪBC News' Eric Strauss and Sony Salzman contributed to this report.Give you an analogy, here. "That would not be available to make the drugs that we've had - and Trump would not have received those antibodies," Srivastava said. The one approved proposal relied on tissue already acquired, "with no need to acquire additional tissue," according to the board's report it is also noted that "tissue from miscarriage was a viable alternative to HFT."ĭeepak Srivastava, president of the Gladstone Institutes and immediate past president of the International Society for Stem Cell Research, said it's important to note that if the Trump administration's ban was in place when the cell line Regeneron uses was made - the innovations that have come from it would not have been possible - including testing the treatment Trump received. In August, the HHS ethics board advised rejecting funding for nearly every proposal involving fetal tissue: 13 out of 14. But the effectiveness of the antibody's ability to neutralize the virus was tested using a cell line derived from an aborted fetus in the 1970s. The Regeneron cocktail was developed using mouse and hamster cells. I just think it's incredibly hypocritical across the board," said Lawrence Goldstein, member of the National Institutes of Health's Human Fetal Tissue Research Ethics Advisory Board and senior faculty member at the University of California at San Diego. "President Trump has been an outspoken opponent of fetal tissue research - and he used it. The disclosure has raised anew questions about the ethical use of fetal tissue and stem cells in groundbreaking research, ahead of a presidential election in which Trump has cast himself as a fierce anti-abortion candidate. The experimental antibody treatment taken by President Donald Trump to treat COVID-19, which he called a "cure," was developed using cells derived from human fetal tissue - a research technique that his administration has sought in general to limit.
