Scripps scientists find way to transform mature human cells into stem cells

Scripps Research Institute scientists have made a significant leap forward in the drive to find a way to safely reprogram mature human cells and turn them into stem cells, which can then change into other cell types, such as nerve, heart, and liver cells. The ability to transform fully mature adult cells such as skin cells into stem cells has potentially profound implications for treating many diseases.

Marcus evans Summit highlights potential growth, innovation in drug discovery

Drug discovery scientists need to broaden their approaches to pharmaceutical research and development (R&D) and Medicinal Chemistry, to take advantage of untapped opportunities, says Torsten Hoffmann, Head Discovery Chemistry at F. Hoffmann La Roche, Basel, Switzerland. Chemical Biology allows room for innovation, but is often overlooked by scientists in the industry.

Reprogrammed amniotic fluid cells can generate iPS cells

Reprogrammed amniotic fluid cells can generate all types of body cells. High hopes rest on stem cells: one day, they may be used to treat many diseases. To date, embryos are the main source of these cells, but this raises ethical problems. Scientists at the Max Planck Institute for Molecular Genetics in Berlin have now managed to convert amniotic fluid cells into pluripotent stem cells.

Skin to blood transformation in the lab

In a new study scientists have successfully transformed human skin cells into blood without first being sent through a primordial, stem-cell-like state. The findings were published online in the journal Nature. Earlier work has shown that fibroblast cells from mouse skin, treated with the right cocktail of chemicals, can be transformed into neurons and heart muscle. This is a first with human cells.

New York Stem Cell Foundation names first six NYSCF Investigators

In an expansion of its ongoing effort to promote the next generation of stem cell scientists, The New York Stem Cell Foundation (NYSCF) today named the first six NYSCF Investigators. Each of the NYSCF-Robertson and NYSCF-Helmsley Investigators will receive up to $1.5 million over the next five years to expand their own laboratories, train other scientists and foster innovative high-risk/high reward research to explore the therapeutic potential of stem cells derived from humans and model organisms.

Researchers identify gene activator that allows stem cells to transform any type of cell

Emerging Healthcare Solutions, Inc. was energized Monday by news that researchers in North Carolina may have identified the gene activator that allows stem cells to reproduce and become any type of cell in the body.

Study establishes critical roles for cancer-causing Myc gene in stem cell biology

Stem cells might be thought of as trunks in the tree of life. All multi-cellular organisms have them, and they can turn into a dazzling variety other cells-kidney, brain, heart or skin, for example. One class, pluripotent stem cells, has the capacity to turn into virtually any cell type in the body, making them a focal point in the development of cell therapies, the conquering of age-old diseases or even regrowing defective body parts.

Scientists develop new synthetic material to grow stem cells

Human pluripotent stem cells, which can become any other kind of body cell, hold great potential to treat a wide range of ailments, including Parkinson's disease, multiple sclerosis and spinal cord injuries. However, scientists who work with such cells have had trouble growing large enough quantities to perform experiments - in particular, to be used in human studies. Furthermore, most materials now used to grow human stem cells include cells or proteins that come from mice embryos, which help stimulate stem-cell growth but would likely cause an immune reaction if injected into a human patient.

Advanced Cell Technology to obtain patent for cellular reprogramming, generation of iPS cells

Advanced Cell Technology, Inc. announced today that it is positioned to obtain significant patents relating to cellular reprogramming and the generation of induced pluripotent stem (iPS) cells. iPS cells are similar to embryonic stem (ES) cells, except they are generated from adult cells such as skin using certain reprogramming factors, without the controversial use of embryos. Although human iPS cells were first produced in 2007, ACT has been working on inducing pluripotency, with positive results, for more than a decade. The Company's efforts go back to the 1990s, providing (through existing patent filings and continuations) some of the earliest priority dates in the field.

StemCells second-quarter net loss decreases to $4.61 million

StemCells, Inc., a leading stem cell company developing and commercializing novel stem cell therapeutics and tools for use in stem cell-based research and drug discovery, today reported financial results and business highlights for the second quarter ended June 30, 2010.

Researchers reprogram human embryonic stem cells to iPS cells for use in regenerative medicine

Human embryonic stem (ES) cells and adult cells reprogrammed to an embryonic stem cell-like state-so-called induced pluripotent stem or iPS cells-exhibit very few differences in their gene expression signatures and are nearly indistinguishable in their chromatin state, according to Whitehead Institute researchers.The pluripotency of ES cells fueled excitement over their use in regenerative medicine. While ethical hurdles associated with the clinical application of human ES cells appeared to have been overcome with the development of methods to create iPS cells, some recent research has suggested that ES and iPS cells have substantial differences in which sets of genes they express.

Human fat tissue can be reprogrammed to yield clinically useful stem cells: Research

Australian scientists from the Monash Institute of Medical Research have "reprogrammed" adult mouse fat cells and neural cells to become stem cells that can differentiate into a variety of different cells (pluripotency). The cells, called "induced pluripotent stem cells" are nearly identical to the naturally occurring pluripotent stems cells, such as embryonic stem cells, which are highly pluripotent, in short supply and their access restricted in the U.S.

Tet 1 protein helps stem cells renew themselves and stay pluripotent: Researchers

Take a skin cell from a patient with Type 1 diabetes. Strip out everything that made it a skin cell, then reprogram it to grow into a colony of pancreatic beta cells. Implant these into your patient and voilà! She's producing her own insulin like a pro.

Experts use Mexican aquatic salamander to study evolution and genetics of stem cells

Dr Andrew Johnson is speaking today (12 July) at the UK National Stem Cell Network annual conference. He and his team from the University of Nottingham have been using a Mexican aquatic salamander called an axolotl to study the evolution and genetics of stem cells - research that supports the development of regenerative medicine to treat the consequences of disease and injury using stem cell therapies. This team has found that there are extraordinary similarities in the development of axolotls and mammals that provide unique opportunities to study the properties of embryonic stem cells and germ cells.

Frozen blood samples shows promise to study mechanism of blood disorders

Cells from frozen human blood samples can be reprogrammed to an embryonic-stem-cell-like state, according to Whitehead Institute researchers. These cells can be multiplied and used to study the genetic and molecular mechanisms of blood disorders and other diseases.

New insights into cancer hallmarks in induced pluripotent cells

The therapeutic potential of embryonic stem cells has been an intense focus of study and discussion in biomedical research and has resulted in technologies to produce human induced pluripotent stem cells (hiPSCs). Derived by epigenetic reprogramming of human fibroblasts, these hiPSCs are thought to be almost identical to human embryonic stem cells (hESCs) and provide great promise for patient-tailored regenerative medicine therapies.
