Newswise ANN ARBOR, Mich. The University of Michigans second human embryonic stem cell line has just been placed on the U.S. National Institutes of Healths registry, making the cells available for federally-funded research. It is the second of the stem cell lines derived at U-M to be placed on the registry. The line, known as UM11-1PGD, was derived from a cluster of about 30 cells removed from a donated five-day-old embryo roughly the size of the period at the end of this sentence. That embryo was created for reproductive purposes, tested and found to be affected with a genetic disorder, deemed not suitable for implantation, and would therefore have otherwise been discarded when it was donated in 2011. It carries the gene defect responsible for Charcot-Marie-Tooth disease, a hereditary neurological disorder characterized by a slowly progressive degeneration of the muscles in the foot, lower leg and hand. CMT, as it is known, is one of the most common inherited neurological disorders, affecting one in 2,500 people in the United States. People with CMT usually begin to experience symptoms in adolescence or early adulthood. The embryo used to create the cell line was never frozen, but rather was transported from another … Continue reading →

Public release date: 25-Apr-2012 [ | E-mail | Share ] Contact: Kim Irwin kirwin@mednet.ucla.edu 310-206-2805 University of California - Los Angeles Health Sciences Can one feel too attached? Does one need to let go to mature? Neural stem cells have this problem, too. As immature cells, neural stem cells must stick together in a protected environment called a niche in order to divide so they can make all of the cells that populate the nervous system. But when it's time to mature, or differentiate, the neural stem cells must stop dividing, detach from their neighbors and migrate to where they are needed to form the circuits necessary for humans to think, feel and interact with the world. Now, stem cell researchers at UCLA have identified new components of the genetic pathway that controls the adhesive properties and proliferation of neural stem cells and the formation of neurons in early development. The finding by scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA could be important because errors in this pathway can lead to a variety of birth defects that affect the structure of the nervous system, as well as more subtle changes … Continue reading →

MARLBOROUGH, Mass.--(BUSINESS WIRE)-- Advanced Cell Technology, Inc. (ACT; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Data and Safety Monitoring Board (DSMB), an independent group of medical experts closely monitoring the Companys three ongoing clinical trials, have recently authorized the Company to move forward with enrollment and treatment of additional patients with Stargardts disease (SMD). In the U.S. SMD trial, ACT will screen and enroll patients for the second cohort, who, in keeping with trial protocol, will be injected with 100,000 retinal pigment epithelial (RPE) cells - as compared with the 50,000 cell dose used in the patients of the first cohort. The Company has also been approved to treat the final two patients to round out the initial dosing arm in its European trial. The use of pluripotent stem cells to derive RPE cells, and the use of the resulting RPE cells for treating a wide range of macular degenerative disorders, are covered by a robust patent portfolio owned by ACT, including a number of issued broad patents in key world markets. DSMB authorization to move to the next higher dosage of cells in our U.S. clinical trial and complete the treatment of … Continue reading →
