| Cloning is the process of creating an identical copy of an original. A clone in the biological sense, therefore, is a multi-cellular organism that is genetically identical to another living organism. Sometimes this can refer to "natural" clones made when an organism reproduces asexually, but in common parlance the clone is an identical copy by some conscious design. The word was coined by the British geneticist J. B. S. Haldane in 1963, and is derived from the Greek word for "twig", klon. |  |

| Opponents Of Michigan Stem Cell Proposal Begin Campaign To Defeat It Opponents of a proposed ballot initiative to loosen Michigan's restrictions on human embryonic stem cell research on Monday launched a campaign to defeat the measure, saying it would lead to human cloning, the Detroit News reports. State Sen. |
| Supporters Of Embryonic Stem Cell Research Question McCain's Support, The Hill Reports Supporters of increased federal funding for human embryonic stem cell research are concerned that Republican presidential candidate Sen. John McCain (Ariz.) would do an "about-face" on the issue to appeal to abortion-rights opponents if he is elected, The Hill reports. |
| Protein Key To Control, Growth Of Blood Cells New research sheds light on the biological events by which stem cells in the bone marrow develop into the broad variety of cells that circulate in the blood. The findings may help improve the success of bone marrow transplants and may lead to better treatments for life-threatening blood diseases. "As we better understand the biological pathways that regulate the growth of stem cells, we may identify new approaches for treating blood disorders," said study leader Wei Tong, Ph.D. |
| Mesoblast Limited Stem Cells Regrow Knee Cartilage In Severe Post-Menopausal Osteoarthritis Australia's regenerative medicine company, Mesoblast Limited (ASX:MSB)(PINK:MBLTY), announced successful preclinical trial results which showed that its proprietary adult stem cells regenerated and regrew damaged knee cartilage in post-menopausal osteoarthritis. |
| Childhood Brain Tumor Traced To Normal Stem Cells Gone Bad An aggressive childhood brain tumor known as medulloblastoma originates in normal brain "stem" cells that turn malignant when acted on by a known mutant, cancer-causing oncogene, say researchers from Dana-Farber Cancer Institute and the University of California, San Francisco (UCSF). Reporting in the Aug. 12 issue of Cancer Cell, the scientists say they have uncovered new origins for these tumors from early stem cells as well as more mature cells. |
| Yale Researchers Discover Tiny Cellular Antennae Trigger Neural Stem Cells Yale University scientists reported evidence suggesting that the tiny cilia found on brain cells of mammals, thought to be vestiges of a primeval past, actually play a critical role in relaying molecular signals that spur creation of neurons in an area of the brain involved in mood, learning and memory. The findings are published online in the journal Proceedings of the National Academy of Science. |
| BIO Welcomes Advances In Stem Cell Research BIO President and CEO Jim Greenwood issued the following statement regarding the news that researchers at the Harvard Stem Cell Institute created 20 disease-specific stem cell lines thru the new induced pluripotent stem cell (iPS) technique: "The creation of stem cells lines carrying the genes or genetic components of ten diseases is a great step forward in the quest to understand, treat and eventually cure disease. |
| StemCells, Inc. To Present On Batten Disease To The California Institute Of Regenerative Medicine's Oversight Committee StemCells, Inc. (NASDAQ:STEM) announced that it has accepted an invitation by the California Institute of Regenerative Medicine (CIRM) to present on Batten Disease at the upcoming meeting of CIRM's Independent Citizens Oversight Committee (ICOC).

| Putting MicroRNAs On The Stem Cell Map Embryonic stem cells are always facing a choice-either to self-renew or begin morphing into another type of cell altogether. It's a tricky choice, governed by complex gene regulatory circuitry driven by a handful of key regulators known as "master transcription factors," proteins that switch gene expression on or off. |
| Scientists Replicate Diseases In The Lab With New Stem Cell Lines A set of new stem cell lines will make it possible for researchers to explore ten different genetic disorders-including muscular dystrophy, juvenile diabetes, and Parkinson's disease-in a variety of cell and tissue types as they develop in laboratory cultures. Researchers led by Howard Hughes Medical Institute investigator George Q. Daley have converted cells from individuals with the diseases into stem cells with the same genetic errors. |
