Digging into the multiple ways to get stem cells

multiple ways to get stem cells

I get great questions from readers of The Niche including, “Are there multiple ways to get stem cells?” The answer is “yes.” Why is this important? The different sources of stem cells can impact both their use in basic research and their potential clinically. My goal in today’s post is to give an overview of …

‘We don’t want to freak people out’: about that Jacob Hanna human embryo model startup

Jacob Hanna Renewal Bio

Stem cell biologist Jacob Hanna has a new startup called Renewal Bio. Its goal is to harvest cells or tissues from human embryo or fetus models for clinical use. I believe that their commercial ambitions have so far outstripped careful thought and discussion in the broader community of researchers. There are major risks here for …

Dura et al sperm development

We often don’t think of them that way but reproductive cells like sperm and egg are also relatives of stem cells, and it turns out that there are stem cells that make the reproductive cells too like sperm stem cells. Sperm and germ cell stem cells DNMT3A-dependent DNA methylation is required for spermatogonial stem cells …

George Church chat: CRISPR people, Zika, weapons

George-Church

I talked last year about human genetic modification by CRISPR with George Church a year ago. Now we’ve followed up with a long chat on this topic going into much more detail and with questions on recent developments. Each question is listed numerically and then there is a back and forth on that question with George …

Steven Pinker interview: case against bioethocrats & CRISPR germline ban

Steven-Pinker

CRISPR-Cas9 gene editing technology is red-hot right now and I’ve been doing interviews with various thought leaders on it, which today includes Steven Pinker. This technology has great power for research in the lab and there are hypothetical transformative clinical applications of CRISPR too. The latter efforts could include experimental attempts at reversal of disease-causing …

A critique of the Witherspoon stem cell report

Lately I have been critical of an ultra-conservative political think tank-like foundation called the Witherspoon Institute. They have recently joined the federal lawsuit as friends of the plaintiffs suing to stop federal funding of embryonic stem cell research. The Witherspoon Council has just published a 100+ page report on stem cells in the very conservative, somewhat obscure …

New Republican Governors Start Attack On Most Promising Stem Cell Research

Last Fall’s mid-term election brought into office several new Republican Governors who during their campaigns used strong, anti-embryonic stem (ES) cell research rhetoric. For example, then candidate for Governor of Wisconsin, Scott Walker (now the Governor) used some of the strongest language, which was ironic considering that human ES cells were first produced in Wisconsin …
