What is a teratoma? Research & treatment

What is a teratoma? human stem cell teratoma knoepfler lab sm

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? Teratomas are germ cell tumors. What this means is that the cells …

Weekly reads: cats, COVID, CIRM, cancer stem cells, MS

diana farmer and aijun wang uc davis 1

There have been many other interesting scientific and specifically regenerative medicine developments and papers this past week including with CIRM and exciting CIRM funding to UC Davis so read on, but first a somewhat random question: are you more of a cat person or dog person? I’d say I’m both. But our big dog is …

3 Ways Stem Cells Theoretically May Help John McCain Beat Brain Tumor

John_McCain_brain-cancer-e1500667982554

I was really sad when I heard about John McCain’s diagnosis with a glioblastoma, a particularly nasty type of brain tumor that we study in my lab when it shows up in children. My own battle with prostate cancer starting almost 8 years ago might have sensitized me to this news even though I’m in …

Can Stemcentrx thrive as a biotech killing cancer stem cells?

stemcentrx.2x519

A stem cell biotech in the news this week was one that had mostly flown under the radar previously with aim to zap cancer stem cells. Stemcentrx has a focus on killing cancer stem cells as a novel approach to treating cancer. Antonio Regalado had a nice article yesterday on the company. He reports that Stemcentrx has …

Are glioma stem cells a path to better outcomes?

Glioblastoma

Glioblastoma and other related malignant glioma tumors including diffuse intrinsic pontine glioma (DIPG) are some of the most devastating of all human cancers, and glioma stem cells may contribute to the lethality. You can see an image of a glioma (the white area in the brain scan) from Wikipedia above. These brain tumors usually kill …

Secret Not so Secret Recipe for Safer iPS cells

IPS cells, induced pluripotent stem cells, Knoepfler lab, stained for TRA-1-60, an ES cell marker., where do stem cells come from?

Just how tumorigenic are iPS cells?  The field really doesn’t know at this point. However, a steady stream of papers have raised red flag after red flag about genomic and epigenomic alterations/mutations that are linked to cancer. Of course, then there is the fact that all the genetic changes actually used to make reprogrammed cells …

Devil in the details: small oncogenic lesions in iPS cells & ESC

Loring-in-lab-1

Yesterday I wrote about how difficult it is to tell different cell lines apart, including normal stem cells and cancer stem cells, especially since some accumulate accumulate oncogenic mutations that may make them seem more similar. A new paper is coming out that makes this case on a genomic level. Tomorrow’s Cell Stem Cell edition …
