How Much of Your Body Is New Every Year? | Compilation

TL;DR

Stem cells have the potential to regenerate various body parts, and scientists are exploring different sources, including menstrual fluid, for these cells.

Transcript

every year around January 1st you'll  hear people say new year new me and while it's   not tied to the calendar there might actually be  some truth to that statement like when your body   literally makes new parts of itself from regrowing  your liver after donating part of it or when you   grow a new spleen that you didn't even know you  grew true ...

Key Insights

• 💄 Stem cells are flexible cells that can differentiate into different tissues, making them valuable in regenerative medicine.
• 😀 Embryonic stem cells have significant potential but face ethical concerns and limited availability.
• ❓ Menstrual fluid contains mesenchymal stem cells that exhibit similar plasticity to embryonic stem cells.
• 💊 Menstrual mesenchymal stem cells can differentiate into multiple tissue types, offering a promising source for regenerative medicine.
• ☠️ Mesenchymal stem cells derived from other sources, such as bone marrow and umbilical cord blood, have limitations compared to menstrual stem cells.
• 💨 Menstrual mesenchymal stem cells have shown success in treating stroke, Alzheimer's, diabetes, liver function, infertility, and wound healing in animal studies.

Questions & Answers

Q: What are stem cells and why are they important in regenerative medicine?

Stem cells are flexible cells in the body that can transform into different tissue types. They are vital in regenerative medicine as they have the potential to repair and replace damaged tissues.

Q: What are the challenges associated with using embryonic stem cells?

Ethical concerns regarding the destruction of embryos and limited availability of fresh embryonic stem cells from IVF procedures pose obstacles in their use for research and therapies.

Q: How are mesenchymal stem cells different from embryonic stem cells?

Mesenchymal stem cells, harvested from adults, offer an ethically viable alternative to embryonic stem cells. While they are not as versatile, they have significant plasticity and can differentiate into various tissue types.

Q: How were mesenchymal stem cells discovered in menstrual fluid?

Scientists suspected that the uterus utilized stem cells during menstruation. In 2007, they isolated cells from menstrual fluid and confirmed that these cells had stem cell characteristics, including the ability to clone and differentiate into different cell types.

Summary & Key Takeaways

• Stem cells are flexible cells that can differentiate into different types of tissues, making them valuable in regenerative medicine.

• Embryonic stem cells offer the most potential but are ethically debated and difficult to obtain.

• Mesenchymal stem cells, harvested from adults, are ethically more viable but harder to access until the discovery of stem cells in menstrual fluid.

• Menstrual mesenchymal stem cells have similar plasticity to embryonic stem cells and can differentiate into various tissue types.
