Embryonic stem cells, reprogrammed skin cells have inherent differences

Kathrin Plath

UCLA researchers have found that embryonic stem cells and skin cells reprogrammed into embryonic-like cells have inherent molecular differences, demonstrating for the first time that the two cell types are clearly distinguishable from one another.

The data from the study suggest that embryonic stem cells and the reprogrammed cells, known as induced pluripotent stem (iPS) cells, have overlapping but still distinct gene expression signatures. The differing signatures were evident regardless of where the cell lines were generated, the methods by which they were derived or the species from which they were isolated, said William Lowry, a researcher with

Stem Cell Possibilities in Autism Research

Announcer: Recently, Dr. Ricardo Dolmetsch, an associate professor of neurobiology at Stanford, spoke with National Institute of Mental Health Director Dr. Thomas Insel. Devoted to Autism Spectrum Disorder research, Dr. Dolmetsch and his colleagues have generated stem cells from children with autism allowing them to study how the brain develops in children with ASD.

Dr. Thomas Insel: I thought a good place to begin the conversation was to ask you about your interest in autism and how that happened. You’re someone who trained in calcium channels… worked on very basic problems in molecular biology and now you’re interested in autism…

Dr.

“Stem cell revolution” movie

Featuring beautiful hand-drawn animations and interviews with leading stem cell scientists, STEM CELL REVOLUTIONS charts the history and scientific evolution of stem cell research – from the earliest experiments that first revealed stem cells in the body, to leading current scientific and clinical developments.

Supported by the Wellcome Trust and made by the same team as behind our four short films, Stem Cell Stories, this documentary is a genuinely creative collaboration between scientists and filmmakers.

STEM CELL REVOLUTIONS features eminent international scientists in stem cell research including Nobel Laureate Sir Martin Evans and Sir Ian Wilmut, creator of Dolly the sheep,

Transplants: human-pig embryos from stem cells

Scientists have for the first time grown embryos that contain a combination of pig and human stem cells, in a step toward one day growing transplantable organs, a study said on Thursday.

However, the research remains at a very early stage and proved more difficult than expected, the researchers reported in the peer-reviewed journal Cell.

“This is an important first step,” said lead investigator Juan Carlos Izpisua Belmonte, a professor in the Salk Institute of Biological Studies’ Gene Expression Laboratory.

“The ultimate goal is to grow functional and transplantable tissue or organs, but we are far away from that.”

Researchers cure mice with damaged spines using human iPS cells

A team at Keio University has used stem cells to cure mice whose hind legs were paralyzed due to spinal cord damage, the researchers reported Wednesday at a Tokyo symposium.
The team transplanted neural stem cells grown from human iPS cells.

Team leader Hideyuki Okano, a physiology professor at Keio, said it is the first time in the world in which the curative effects of “induced pluripotent stem cells,” or iPS cells, have been confirmed.
Currently, there is no effective treatment for spinal nerve damage and treatment using iPS cells gives hope of a cure.

“It is valuable that treatment using human iPS
