CBS News: The Trouble With Adult Stem Cells. Research Shows Why They Won’t Displace Embryonic OnesBY ANDREW MOSEMAN When scientists first created induced pluripotent stem cells (iPS cells) three years ago, they were hailed as a game-changing advance for medicine: Scientists ...
(VSELs) into adulthood, thus forming a reserve 'back-up pool' of stem cell precursors for adult issues.17,46,47 VSELs are slightly smaller than mature erythrocytes.48 The small size of these cells (~3–5 μm in mice and 4–7 μm in humans) and the paucity of mitochondria are ...
Undifferentiated Ethics: Why Stem Cells from Adult Skin Are as Morally Fraught as Embryonic Stem Cells Hailed as a potential alternative to embryonic stem cells, induced pluripotent stem cells (iPS cells) raise their own ethical dilemmas BySally Lehrman San Francisco— When researchers first demonstrat...
Three types of cells in the body undergo mitosis. They aresomatic cells, adult stem cells, and the cells in the embryo. Somatic cells – Somatic cells are the regular cells in the body of multicellular organisms. What are the steps of cytokinesis?
Why is water important for metabolic reactions? Why is eating a well-balanced diet with a variety of foods healthier than a diet of only a few different types of foods? Why are stem cells important for tissue health? Why is a regular checkup for cancer important?
Do you think forests fires are more harmful or helpful and why? Give three examples. Think of an adult learning situation that was very successful. How does neuroscience help explain why it was successful? What is interstitial fluid and why is it important? Explain the importance of bone marro...
Imitation in young children: when who gets copied is more important than what gets copied. Unlike other animals, human children will copy all of an adult's goal-directed actions, including ones that are clearly unnecessary for achieving the demon... M Nielsen,C Blank - 《Dev Psychol》 被引...
"Protecting our underwater heritage is extremely important and increasingly urgent as no site or shipwreck is now out of bounds for treasure hunters. New technologies have made deep-water wrecks easily accessible and these technologies are getting cheaper," warns Lyndel Prott. According to estimates ...
Why are childhood cancers more likely to have a hereditary predisposition than adult-onset cancers? How might primary tumors exhibit metastatic powers as soon as they form? Explain the rationale behind targeting the tumor microenvironment instead of the tumor cells in cancer therapy. In your answe...
Cells are the fundamental building blocks of life from the simplest one-celled organisms to the most complex living organisms. One thing we have not seen in nature are huge cells either as a single-celled organism or even in multicellular organisms. There seems to...
