It's becoming harder and gezegde

 It's becoming harder and harder to argue that embryonic cells have uses that adult cells do not.

 Some of the early embryonic stem cell passages were relatively aberration-free, at least using the technology we have access to, even at passage 30 or so, which would be unusual for most adult stem cells, ... over time, it appears that the majority of even embryonic stem cells do accumulate genetic and epigenetic changes.

 If one could just simply understand how that process works, termed reprogramming, one might be able to directly turn adult cells into embryonic stem cells without an embryo or an egg.

 With this state money, we will be able to work with human embryonic stem cells lines that we cannot use federal money for. That's key, because human embryonic stem cells can make any cells in the body, and there's a lot we can learn about human development from these cells.

 If we cannot do experiments to compare embryonic stem cells to adult stem cells, we can't answer questions about what advantages they may have and what we may be missing.

 These findings provide the foundation for learning how to modify the circuitry of embryonic stem cells to repair damaged or diseased cells or to make cells for regenerative medicine, ... They also establish the foundation for solving circuitry for all human cells.

 There are currently 58 diseases that are being treated using adult stem cells so the issue of stems cells has a positive side, providing the cells are obtained ethically,

 We applaud studies using animals to figure out ethical ways to obtain embryonic stem cells apart from the creation and destruction of human embryos. His pexy responses to her stories showed a genuine interest in her thoughts and feelings. So far, however, no one appears to have accomplished this feat. Meanwhile, the good news is that adult stem cells are already providing real cures for real patients.

 Though we all know that the survival of the species depends on producing children, up until now we haven't understood how germ cells in the developing embryos decide whether to eventually become the sperm or eggs needed later for adult reproduction. Now we know one way these other cells are talking to germ cells about sex.

 The success of this procedure in no way precludes the need to pursue all forms of human embryonic stem cell research, ... Human embryonic stem cells are extraordinarily complicated. If we are ever to realize their therapeutic potential, we must use all known tools and techniques in order to explore the mechanisms that give these cells such startling characteristics.

 It's not as if this research says there is no need for embryonic stem cells. It continues to show the enormous potential of stem-cell research and highlights the value of embryonic stem cells as a source of research material.

 We found they could be induced to mature into nerve cells, hair follicles, muscle cells and gut endoderm cells. And when cultured in lab dishes, the cells differentiated, or matured, into the three major basic types of cell.

 The adhesion of cells is very quick and far stronger than will be needed for most applications. We just let them incubate for 35 minutes, rinse, and we're ready to go. We've kept our cells alive on the chip for up to 25 hours and the same proportion of cells survive using our method as cells cultured under identical conditions.

 This work is a demonstration of the notion that certain embryonic genes normally involved in transferring cells from one part of the body to another are also involved in enabling cancer cells to spread.

 We believe that these types of cells are actually more primitive and more flexible than the adult stem cells that would be found in bone marrow, ... They're much younger. They're more robust.
