What is Tissue Engineering?

Articles , , , , , 6 Comments

Tissue engineering (also called “Regenerative
Medicine”) refers to the attempt to create functional human tissue from cells in a laboratory. Its ultimate goal is to be a cure, not merely
treatment – by repairing or replacing tissues and organs that fail due to disease, genetic
errors, congenital abnormalities, or traumatic injury. Tissue engineering relies on four important
factors: the right cells to do the job, the right environment, such as a scaffold, to
support the cells, the right biomolecules, like growth factors, to make those cells healthy
and productive, and physical and mechanical forces to influence the development of the
cells. The cells can be directly harvested from the
target organ, developed from precursor—or stem—cells, or taken from lines grown in
the lab all, ideally, from the patient, as that limits problems with rejection. The supporting structures can be derived from
donor tissue from natural or synthetic polymers made to order for their strength or endurance. Biomolecules can be added directly, or coaxed
from the cells that take up residence on the scaffold. Sometimes the scaffolds dissolve
over time, but others remain to provide support to the organ. Some examples of tissues and organs that have
already been successfully tissue engineered and implanted in humans include bladders,
small arteries, skin grafts, cartilage and even a full trachea.

    Thank you for sharing this informative video~!😃

  • Jesus Enrique Campos Pacheco

    It was an awesome explanation. Very practical and didactic!

    Umm this is not 60 seconds of science but 1:59 seconds lol
    Good job tho it was a very informative video and it taught me a lot and gave me a better understanding

    do specialize in coal as well?

    Stem cells is an amazing field in development at the moment. It has huge potential in dealing with one of the main problems with aging and that is cell loss. Making organ regeneration a reality is just incredible. We have a healthspan discord discussing biotechnology and ways to improve quality of life (https://discord.gg/ftSbffu).

    Thanks guys, i'm writing a thesis about Tissue Engineering and this was really helpful and gave me a better undestanding of Tissue Engineering. Unfortunately I haven't quite understood what the biomolecules are there for 🙂
    I would be glad if I could get an answer or a private message including a short explantion about it or an article explaining it 🙂
