This lecture, by Dr. Nadia Rosenthal, discusses the role of stem cells in the regeneration and repair of tissues, and their possible medicinal application through the harnessing of their regenerative properties. HHMI description: Human tissues vary in their ability to heal and regenerate. The nervous system has weak powers of regeneration, while the skin is quick to make new cells for repair. Mammalian muscle cells are intermediate in their ability to regenerate. Human muscle can regenerate in response to minor wounds and normal wear and tear, but humans will not grow a new bicep, for example, in response to amputation. The heart is the most important muscle in the body and yet has feeble regenerative capabilities. Research into the wholesale production of new replacement organs and limbs is in its infancy, but research into enhancing normal levels of regeneration is progressing rapidly. Recent discoveries concerning the location and characteristics of adult stem cells and the signals that wounded tissue produces to activate stem cells have increased our understanding of regeneration. Insulin-like growth factor 1 (IGF1) is an example of an important stem cell communication molecule. If the activity of the growth factor is experimentally enhanced, muscle regeneration improves.

indeed
i want aging to be cured. i wanna live forever and be young!
wad is all these u mention about ?
Hmm, as a person pursuing further education in medical science I find these videos interesting. Regardless of the material covered in each video, I want to fu** her until the cows come home.
nice page filler.
good video! my names Brianna, kinda feelin bored if any1 wants to join me on cam or wana chat i will be signed on at __ FriendlyFlirts(.COM) __ my user ID there is Brianna_tquuux chat soon xx its FR33 to j0in! mwah
reduce SIR2, SCH9, & RAS2 genes in yeast, life = 6x longer. Mammal counterpart is SIRT1 to resist oxidants, store nutrients. It regulates P-genes to make less cells to fight infections. Much like HST1, no good.
She doesn’t know how to stop aging, look at her!
i love this topic (aging)
