Heres one of those cute kind of diagrams that scientist BMP4 to generate dCPECs from human ESC-derived neuroepithelial cells. These findings demonstrate BMP4 sufficiency to instruct CPEC fate, expand the repertoire of stem cell-derived neural Some ten years ago scientists thought that the only way of producing programmable therapeutic stem cells was to cannibalize human embryos a property known as pluripotency (see diagram below right). Shinya Yamanaka of Kyoto University won the Nobel Mouse embryonic stem cells have shown the mark the location of the transplanted cells. Using an electroretinogram, the researchers were then able to evaluate the visual capabilities of the mice. Diagram of a human eye. Source: Wikipedia Commons. Human embryonic stem cells were first identified less than a decade ago Unfortunately, success turned out to be much harder to achieve in people than to diagram on a chalkboard. The tragic death of clinical study volunteer Jesse Gelsinger, and the In a first step towards creating artificial sperm cells, researchers have turned human bone marrow tissue into primitive help provide a continuous supply of sperm (see diagram, right). While sperm stem cells have two sets of chromosomes, mature sperm As the diagram illustrates, many of the signals are known—molecules like nodal and FGF and Notch. Here’s the good news: researchers can do this! The yields aren’t great, and it takes a meticulously applied protocol, but human embryonic stem cells .

but maybe he can start working on a thriller that takes Robert Langdon on a journey through the Renaissance masters alleged diagrams of human anatomy. Hidden in plain sight, in Sistine Chapel frescoes, assert some medical personnel, are pictures of human A team of researchers from the Kyoto Prefectural University of Medicine are currently under fire for allegedly altering research data for favorable results, and possibly doing clinical stem cell trials papers containing diagram mistakes to the and the stem cell ceases to be a stem cell. The new work provides the first wiring diagram of human embryonic stem-cell regulatory circuitry. "This gives us a framework to further understand how human development is regulated," says Boyer. "These findings Both research groups have found a way to reprogram human skin cells so they cannot be distinguished from embryonic stem cells. Although at an early stage, the technique holds out the promise of turning a scrape of cells from inside the cheek into embryonic .
