Immortal Cells Turn 96

  • Added:  Year ago
  • The world has a lot to thank Henrietta Lacks for, and yet many do not know what she has contributed. From helping to create the polio vaccine to the study of radiation, Henrietta and her HeLa cells have changed the world.

    Millions of years into the future and we literally have walking immortals... assuming they evolve to be human-like..... scary

      Jan Denbert Dayot telomeres are a part of every cell. after each division, they get shorter and shorter, eventually a cell can't divide anymore and it dies.

    • Jan Denbert Dayot

      Also, why aren't we studying what triggers the production of Telomeres? I mean, if we can't produce, we'll instruct those who know how to produce them.... right?

    do the telomeres never shorten? do they shorten at a slower rate? are they resistant to oxidation/ free radicals or are they not exposed to these? how could you make this video without giving even a small hint as to why we think they can live so long and keep duplicating other than saying they 'mutated' ...awesome video which taught me stuff I didn't know, but missing the important how/ why that most people clicking the video were curious to know

    I recently read Doug Ellison's book Health Recovery Secrets. He talks about what Hela cells really are. He says they aren't actually human cells, they are fungal cells. That's why they are immortal. He gives all the same info for free on his blog. Doctors that treat their cancer patients as if they have a fungal infection, have great success.

    This creeps me out so much! I find it very interesting and have a love for biology and other sciences and nothing ever really creeps me out but this is FREAKY to me, billions of cells living from a dead person being distributed and used by thousands of people

    I wish they'd use those Hela Cells to discover immortality soon! I don't care what some people think, I DO want to live forever, regardless of seeing my loved-ones die. it means I can have multiple lovers, multiple children, have a different life each century, and most of all; I'd get to witness going to different galaxies and the death of our Solar System! also, possibly the invention of time-travel, if it ever gets created and I'd get to go back in time to do it all over, and over, and over again!

    Except that this is not the first immortal cell line. You should do a video on germ lines. These are essentially reproductive cells, and if you think about, you should realize that any human that has children has passed on his or her germ line to them. Extended to a much larger time scale, you will see that humans (and pretty much every other cellular living entity) have the potential to live forever through their cell lines. Otherwise stated, all humans today are just the extension of some ancient human, as well as all pre-human species, through some original primordial, cellular creature's germ line (or course, with mutations along the way to make us what we are now). We are all the product of some immortal cell line, and most of us have the capability of continuing our cell line, allowing us to live forever through our progeny (in a certain sense).

    This is hilarious that I found this video. For my summer reading I had to read the Immortal Life of Henrietta Lacks by Rebecca Skloot and it's all about the HeLa cells and what Henrietta went through. About what her family went through. It's basically a biography about Henrietta. It's pretty interesting, I think you guys would like it.

    What's up with these stupid comments?
    Getting a random mutated cells through HPV is not an achievement, it's an accident. If anything the tissue specialist(whos name wasn't even mentioned) that understood the gravity and usefulness of this cell is the real hero in this.
    That's not to say that Henrietta was not a hero, it's just she is an unintentional one.

  • pafnucek
    pafnucek Year ago

    In normal cells the shortening of tellomers in their chromosomes stops them from multiplying infinitely. I wonder If HeLa cells are different in this regard, and if yes, could we eliminate the cancerous growth keeping long lasting chromosomes.

    • Quinn Higginbotham
      Quinn Higginbotham Year ago

      +Pata Fea I thought it was due to cancerous cells producing telomerase, and thus always having a sufficient amount of telomeres during DNA replication.

    • Pata Fea
      Pata Fea Year ago

      the chromosomes don't last particularly long, they are called immortal because they never stop making copies. So as soon as they stopped being cancerous they would stop being immortal.
