Hello hello!

It's a big episode so it was a late night, but the wonderful Dr. Samantha Yammine aka Science Sam is this week's Ologist. She explains what a stem cell is, how they were discovered, what they can do, how they do it, and all the questions scientists still have. 

There are so many studies linked on my website in case you're curious. Also here's an excerpt from an aside that got cut last minute, because it was just too much of me talking. 

Ps: Another scientist championing the possibility of stem cells in the brain? Dr. Fred "Rusty" Gage, a descendant of Phineas Gage, the rail worker whose brain was penetrated by a 43-inch iron bar that exited his skull and clattered to the ground 80 feet away, in 1848. He survived, shockingly, but his personality changed considerably: his social inhibitions vanished and he went a little ...off the rails. We talk more about him in the Ophthalmology episode. But his descendant Dr. Fred "Rusty" Gage became a neuroscientist because what else do you do when your great-grandpa is one of the most studied cases in the history of brains? Also some people doubt that Dr. Gage is the direct great grandson because Phineas was not known to have any kids, but Phineas also, post-accident, developed very surly, sometimes violent moods and was described as a heavy drinker. So who’s to say? He lived for 12 years after the accident, and his skull and the tamping iron that blew through it are in the Harvard University School of Medicine Museum collections should your brain want to get a gander. But yes, if I were a Gage, my family history certainly would be a motivating factor. I would also wear a helmet. Everywhere.

Anyone listen yet? Were you already following Science Sam, or did this ep turn you into a fan? 

All ears,

Stem Cell Biology (CELLS MAKING CELLS) with "Science Sam" aka Samantha Yammine - alie ward

How do our bodies build our bodies? What does a stem cell look like? How do they know what to do? What diseases could stem cells cure? And why is Canada such a hot place for research?

The episode was great, I wish I was paying attention when you asked for questions for this episode. I would have asked when will stem cell scientists be able to grow new teeth for people and what does the doctor know about menstrual blood as a potential source of stem cells. Please forgive my adhd brain if these questions were covered and I missed them.

Alie Ward

These are great ones! I could have chatted with her for hours.

Jaclyn and her cat Phil

I’m about 3/4 of the way through the episode and I’m loving it! (Also as someone from Saskatchewan I’m very proud of how you pronounced it! Definitely not easy haha!)

Wandering Wyatt

Was already a fan. Can’t wait to listen! Now extra curious because of Jaclyn’s comment! I am also originally. from Saskatchewan

I knew absolutely nothing about stem cells before this episode! Like, I knew they...exist...but that was it! I don't think I've ever gone into an Ologies episode with as little prior knowledge about the topic as this one! This was very exciting! Exclamation points!!! I would really like to know more about the possibilities for regeneration of brain tissue. I had a stroke 5 years ago which knocked out my left visual cortex, so I lost my right-side vision (among other things) and I would love to imagine that there's any possibility of ever getting even SOME of it back.

Spencer Parks

Thank you in advance for this one. Sounds fascinating! And I’m sad that aside got cut cause it’s a good one (info and writing) and that guy is so fascinating! Brains are crazy. I read a great book about brain maps (written by an old HS friend). And we appreciate the effort you put into getting these episodes out on time but don’t kill yourself! 😜 Your health is much more important.

If I ever were to have a baby, I know what the umbilical cord's next mission is!

Maria Armero

Just a few hours before listening to the episode I was telling my partner about a workmate who was looking for a freezing service for her child's umbilical cord about ten years ago. I don't have kids so I don't know if this still the case in Spain, but the prices she was talking about were too much for our salaries and it sounded very much like an excentricity. It was fun to learn some more about this. Also, very excited about the technologies that can derive from stem cell investigation. My grandpa died after 10 years with Alzheimer's (he was bedridden for the last 6 years of his life) and I always wondered if I will ever see a cure to such horrible disease in my lifetime. Thanks for this episode. It was also super entertaining (as usual).

Piper Warnick

One important question and it's about the secret at the end of the episode. What kind of plant is it??

Anna Vilnīte

At the end of the episode, when they talked about cloned humans, I remembered about a fantastic series called Orphan Black which is about a huge conspiracy regarding human clones. Tatiana Maslany plays a BUNCH of characters and does a wonderful job, I highly recommend it.

Robin Stumbo

if anyone wants a fun video about scientific research drama/history, BobbyBroccoli on youtube just posted a 2-part video about Hwang Woo-Suk and how he faked human cloning and it's so interesting!

When I was in 9th grade I did a research paper on stem cells and decorated cookies to look like cells and they were the ugliest cookies I’ve ever seen in my life 😂 and were pretty disgusting too 🤷🏼‍♀️

Courtney Kudera

Wow stem cells. I had no idea. I also can't help but think about all the calls folks have gotten for phony stem cells research. Crazy sad.

Alie Ward

I hope it's not for sausage making

Alie Ward

I'm so glad it resonated, Maria!

Alie Ward

SO MANY CHARACTERS. She deserves all of the awards. Just... all of them.

Alie Ward

But they fed the brain with facts, and that's what MATTERS. I applaud the effort, my friend.

Alie Ward

Right? I hope Science Sam helps bust that flimflam for folks.

choirqueer

Wow! That's spectacular. Do you think you might get a neurorestoratologist on the show??

NanoNaturalist

I did my masters (biomedical engineering) on tissue engineering, which involved lots of stem cell work. After I graduated, when I was looking for a job, one of those flim-flam snake oil stem cell treatment companies tried to recruit me and that interview was the WILDEST RIDE I've ever been on.
