British scientists grow tooth in a laboratory | BBC News



Scientists from King’s College London have managed to grow a tooth under laboratory conditions.

While this breakthrough is still a long way from filling in the gaps in anyone’s mouth, researchers say it is filling in the gaps in research.

The team worked in collaboration with Imperial College London, and have now successfully introduced a special type of material that enables cells to communicate between each other..

This means that one cell can effectively tell another to start becoming a tooth cell, which mimics the environment of growing teeth and allows scientists to recreate the process of tooth development in the lab.

Having successfully created the environment needed to grow teeth, scientists now need to work out how to get them from the lab to a patient’s mouth.

  1. So good I posted it Twice ๐Ÿ˜… 0:51 Planting water containers throughout forest floors could provide a fire-fighting resource. Here's a breakdown of the potential benefits:

    # Benefits
    1. *Increased water availability*: Having water containers spaced 50 meters apart could provide easy access to water for firefighting efforts.
    2. *Reduced response time*: With water sources readily available, firefighters could respond more quickly to emerging fires.
    3. *Enhanced firefighting capabilities*: The additional water resources could enable firefighters to combat fires more effectively.

    # Considerations
    1. *Maintenance and upkeep*: Regularly inspecting and maintaining the water containers would be crucial to ensure they remain functional.
    2. *Container durability*: The containers would need to be durable enough to withstand environmental conditions and potential impacts.
    3. *Water refill logistics*: A plan would be needed for refilling the containers, especially during extended fire-fighting operations.
    4. *Environmental impact*: The containers' placement and materials should minimize environmental disruption and avoid harming local ecosystems.

    # Next Steps
    1. *Consult with forestry experts*: Collaborate with forestry professionals to determine the best container placement strategies and ensure environmental considerations are addressed.
    2. *Develop a maintenance plan*: Establish a regular maintenance schedule to ensure the water containers remain functional and effective.
    3. *Assess funding and resources*: Evaluate the costs associated with implementing and maintaining the water container system, and identify potential funding sources or partnerships.

    Your idea has merit, and with careful planning and execution, it could enhance fire-fighting capabilities in forested areas.

  4. What a shame! Youtube is anouncing a trick to cure dementia ilnesses. Just like that. This site should be taken to court and their people to prison for allowing advertising promoting criminal ideas about human health. Its just greed, stronger than decency and honor. This site is simply disgusting, now they are also anouncing fake medicines for hair treatment. Miserable thugs.

  5. Nobody mentioned the cost of this. Let me guess. Only the super rich will be able to afford it firstly. Bit like trying to market space travel to the masses and only Bezos's wife and a few select others can go first.
    And besides…we trust everything that comes out a lab…don't we?.

  6. How about we offer the tools to allow Humans to have more access to their own brains. Then they themselves can consciously regrow which ever biological part they may wish to. Is it not said Humans only use/access a certain limited amount of their brains?

  7. ummm Japan's already done something similar last year where they've come up with a drug that helps regrow tooth which personally is better than figuring out if these "biological tooth" will play nicely with our bodies.

  8. Greetings: Tons of wishes and congratulations. Few lines.

    "Lab Made Tooth: A great leap"

    Wonderful
    Tooth smile gets anxious with soda, smoking and lemonade
    With lab made tooth
    Dull effect of age got a new aid

    Old age should burn
    Do not to go gentle into that night
    Agaist all stressors, lab made tooth wages great fight

    Wonderful Day

  9. 2:21 I am shocked by her lack of knowledge! Japanese scientists have made significant strides in developing a groundbreaking drug that enables the regrowth of human teeth. This innovative treatment, spearheaded by Dr. Katsu Takahashi at Kitano Hospital in Osaka, targets individuals with congenital tooth agenesisโ€”a condition where some teeth never develop due to genetic factors .

    After promising results in animal studies, the first human clinical trials began in September 2024 at Kyoto University Hospital. The initial phase is testing the drugโ€™s safety in 30 adult male participants. Later phases will include young children aged 2 to 7 who are missing teeth due to congenital conditions.

    If the trials continue to show success, researchers hope the drug will be available for general use by 2030. This innovation could offer a natural, long-term alternative to artificial implants and dentures.

    The drug works by targeting a protein called USAG-1, which normally prevents tooth development. By blocking this protein, the treatment reactivates a natural pathway known as BMP (bone morphogenetic protein), which stimulates the growth of new teeth. These new teeth come from dormant "third-generation" tooth buds that exist beneath the gums but typically remain inactive.

    Regrowing teeth will soon be possible !

  10. You guys really need to get rid of the red bar. It really hinders seeing whatever you're discussing and is a major distraction. I don't usually watch your videos because of this very reason. It's on all your others as well.

  11. instead of learning to rebuild them, why arent we tossing money and effort into figuring out why you only get ONE chance at your enamel. once its gone, its gone. it doesnt come back. if we could figure that mystery out, we could better protect the original teeth, and not need new teeth. mine was destroyed by antibiotics as a child, i had 3 teeth removed before i was 12 yrs old. thats not a lack of dental care, there are things that affect your enamel that we didnt know about in the 90s when i was little.
