Cartilage tissue engineering

Author: Allison Van Winkle, 06/30/10

In the body, cartilage has minimal potential to heal itself once damaged, as the tissue is not naturally exposed to a blood supply, and is then prevented from benefiting from the body’s immune response and wound healing capabilities. By using a tissue engineering approach, researchers hope to develop replacement cartilage that can be transplanted into…Read more

Induced publication of stem cells?

Author: David Kent, 06/28/10

Earlier this month, the New Scientist shook up the stem cell community, putting forth the idea that publication speed, frequency, and journal quality might be skewed by where you’re from and who you know rather than the quality of your data. The article, entitled “Paper trail: Inside the stem cell wars” was inspired by an…Read more

NAS guidelines revised; more turmoil at AHRC

Author: Ubaka Ogbogu, 06/24/10

NAS revises stem cell guidelines: The US National Academy of Sciences recently released amendments to its influential and widely adopted voluntary Guidelines for Human Embryonic Stem Cell Research. This is the third set of amendments since the guidelines were first issued in 2005 (previous amendments were issued in 2007 and 2008). Key revisions include: The…Read more

We’re a the ISSCR meeting in San Francisco inviting folks to stop by the Stem Cell Network booth (number 509), sit on our comfy couch and talk about what they’ve enjoyed the most at the 2010 ISSCR annual meeting. Featured here are Bernard Thébaud of the University of Alberta and Rebecca Skinner of the Australian Stem…Read more

Adult stem cells keep you roadworthy

Author: Francina Jackson, 06/17/10

How do adult stem cells work? In healthy tissue the adult stem cell population lies dormant. Dormant stem cells are activated by external trauma signals, which trigger patterns of gene expression and protein biosynthesis, thus activating the stem cells to multiply and regenerate damaged tissue. If you think of your normal tissue as a car,…Read more

A revised map for blood development

Author: Chris Kamel, 06/14/10

Simple diagram that shows the development of different blood cells from  hematopoietic stem cell to mature cells. From Wikipedia. All blood cells arise from the common hematopoietic stem cell and are classified into two lineages: lymphoid cells (B-, T- and Natural Killer [NK] cells) which play an important role in adaptive and innate immune response,…Read more
