Immune Rejection Problems May Be Solved By Embryonic Stem CellsTissues derived from embryonic stem (ES) cells could help to pacify the immune system and so prevent recipients from rejecting them, the UK National Stem Cell Network Science Meeting heard.Scientists Investigate A Fine Balancing Act Between Stem Cells And CancerSpeaking at the UK National Stem Cell Network Annual Science Meeting in Edinburgh, Professor Silvia Marino showed how the mechanisms normally involved in balancing different functions of stem cells may also contribute to cancer. Her team from Barts and the London School of Medicine and Dentistry is currently delving into these mechanisms to understand how stem cells are normally regulated and what role they may play in malignant brain tumours.Cartilage Repair Hope Offered By Stem Cells Tor Arthritis SufferersResearch presented at the UK National Stem Cell Network Annual Science Meeting in Edinburgh could offer hope that bone stem cells may be harnessed to repair the damaged cartilage that is one of the main symptoms of osteoarthritis.Potential To Control Adult Stem Cells Revealed By ScientistsResearch being presented at the UK National Stem Cell Network Annual Science Meeting in Edinburgh represents a step towards the use of Adult Stem Cells (ASCs) to repair damaged tissue. Speaking at the conference in Edinburgh, Professor Cay Kielty of the University of Manchester described how she and her team have uncovered a messaging system that instructs ASCs to contribute to tissue repair in response to chemical signals in the body.Heart Stem Cell Scientist Honored Pioneering Woman Scientist In Keynote SpeechProfessor Christine Mummery, one of the world's leading heart stem cell experts, honoured the memory of Dame Anne McLaren in the keynote lecture of the inaugural UK National Stem Cell Network Science Meeting in Edinburgh. Dr McLaren was an early pioneer of the study of embryonic germ cells and her research directly contributed to the development of IVF treatments and stem cell techniques.German Stem Cell Research Hindered By Qualifying Date RuleA few days before the German Federal Parliament reaches a decision on the Stem Cell Act, the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has reinforced its stance on amending current legislation. "The current qualifying date rule, in particular, strongly impedes German stem cell research," explained DFG Vice President Professor Jorg Hinrich Hacker, while participating in a live chat session on the DFG website.FDA Hearings To Examine Regulation Of Embryonic Stem Cell TreatmentsFDA on Thursday will begin two days of hearings to examine how the agency will regulate human embryonic stem cell therapies, the Wall Street Journal reports.Developing Cancer Treatments Directed At Critical Developmental PathwayResearchers from the University of Pennsylvania School of Medicine and colleagues discovered that the Notch signaling pathway, which determines the development of many cell types, and is also implicated in some cancers, is not universally essential for the maintenance of stem cells. The findings appear this week in Cell Stem Cell, and indicate that inhibitors of Notch may not affect bone marrow stem cells.Secrets Of Cellular Signaling Shed Light On New Cancer Stem Cell TherapiesBy revealing the inner workings of a common cell-to-cell signaling system, University of Michigan biologists have uncovered new clues about mysterious and contentious creatures called cancer stem cells.The findings also have implications for a high-profile breast-cancer drug trial getting underway at the U-M Medical School and two other institutions.
