Hottest Science Topic: Stem Cell Research

Standard

Stem cell therapy is among the most cutting-edge of medical treatments, and scientists are currently studying stem cells for the latest discoveries in cancer, heart disease, spinal cord injuries, and many other diseases deemed incurable. But how exactly does this therapy treat such irreversible conditions? The answer lies in the ability of stem cells to specialize into any cell with a specific function in an organism.

Embryonic stem cells are cells that can be grown with a sperm and egg cell in vitro (in a culture dish in a laboratory.) These are the most versatile, as there has been little growth and differentiation.

Somatic, or adult, stem cells are stem cells found in the organs of fully grown human beings. These cells have not differentiated, but live in stem cell niches of specific organs and tissues that contain specialized cells.

Embryonic stem cells are said to be pluripotent, meaning able to specialize into any cell of the body, while somatic stem cells are generally restricted to their organ of origin. Adult stem cells can be genetically altered to become like embryonic stem cells, creating modified cells called induced pluripotent stem cells

Controversial debates surround the ethics of stem cell research. Because an embryo is a living organism and cells are extracted from blastocysts (5-day old embryos), there are questions about the rights of the embryo. Some may consider this practice as homicidal.

Stem cell research is revolutionary, scientists have found a way to control life at its most basic level. If this is possible, imagine how far medicine could go. Cancerous cells could be replaced with properly reproducing cells, and full organs or limbs could possibly be grown with further research. The possibilities are endless with stem cell therapy!

    Very interesting topic. I see you have the same interests as me. But you already know this. I love talking about science with you!

    Can you explain more about what is being done with stem cell research? You have a lot of information about what is it, but I think you could say more about how this science is being applied to current problems and surgery.

    Besides the controversial ethics part, are there dangers in doing stem cell surgery/implants? Is there any information on people who have gotten stem cell surgery where it has developed abnormally?

    Good work!
