The cloning process resulted in small new larvae and original larvae that were substantially smaller.

The implications for disease treatment could be significant. Reprogramming adult stem cells into embryonic stem cells could generate a potentially limitless source of immune-compatible cells for tissue engineering and transplantation medicine. A patient's skin cells, for example, could be reprogrammed into embryonic stem cells. Those embryonic stem cells could then be prodded into becoming various cells types -- beta islet cells to treat diabetes, hematopoetic cells to create a new blood supply for a leukemia patient, motor neuron cells to treat Parkinson's disease.

This represents a significant milestone, as previous methods involved cloning, which takes more time and generally costs more. This new research should reduce the cost and increase the availability of several drugs.

Oregon Health & Science University recently reported the successful derivation of stem cells from cloned monkey embryos. While embryonic stem cells have been made from cloned embryos in a mouse, this is the first time they have been produced in a primate.

Scientists introduced adeno-associated virus to germline stem cells in goats and mice. AAV stably transduced male germ line stem cells and led to transgene transmission through the male germ line.

Now, researchers have cloned a novel aluminum-tolerant gene in sorghum and expect to have genetically engineered aluminum-tolerant sorghum lines by next year. Sorghum is an important food crop in Africa, Central America and South Asia and is the world's fifth most important cereal crop.

It's a solid evolutionary strategy. Creatures that produce scads of genetically identical offspring -- like microbes, plants or water fleas -- offer answers about the clones raised in near-identical environments that turn out differently than their kin. How is the greater good of a genetic pool of identical organisms affected when a few individuals break from the developmental pack?

The finding reveals one of the key mechanisms by which the body detects temperature sensation. But in so doing it also illuminates a mechanism that mediates how the body experiences intense stimuli -- temperature, in this case -- that can cause pain.

A new study, however, identifies a "master regulator" of this regeneration process not only for skin, but for many epithelial tissues including breast, prostate, and urogenital tract. The findings also have implications for cancers of the skin, breast and prostate, which are among the most common human malignancies.

Now, a new technique may allow scientists to create a melanoma vaccine able to stimulate helper T cells. The approach may also aid in the development of other vaccines against cancers or infectious diseases.

Although the implications for human eggs are not yet clear, the findings are of interest because of the ethical and practical concerns surrounding the need for fresh human oocytes for similar nuclear-transfer procedures using human cells.

John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. Uniparental embryonic stem cells are an appealing alternative source of patient-derived embryonic stem cells, as they have several advantages over embryonic stem cell lines generated by somatic cell nuclear transfer (also known as therapeutic cloning).
