Synthetic embryos have been implanted into monkey wombs
Embryos made from stem cells, rather than an egg and sperm, appear to generate a short-lived pregnancy-like response in monkeys.
Drug cocktail makes stem cells that could grow organisms from scratch
Researchers at Tsinghua University in China have developed a new drug cocktail that can convert cells into totipotent stem cells, the very seeds of life. These cells can differentiate into any cell in the body, potentially bypassing the need for sperm and eggs to grow an organism.
Researchers turned fat cells into stem cells to repair injuries | The Burn-In
Despite the fact that some forms of stem cell research are highly controversial, there is no denying that they are a potent treatment for many conditions. Of course, it isn't the stem cells themselves that cause problems-but rather where they come from.
Aided by stem cells, a lizard regenerates a perfect tail for first time in more than 250 million years: Experiment helps inform efforts to improve wound-healing in humans
Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube. Now, a study describes how stem cells can help lizards regenerate better tails.
Sound waves convert stem cells into bone in regenerative breakthrough
Regrowing or replacing bone lost to disease is tricky and often painful. In a new study Australian researchers have found a relatively simple way to induce stem cells to turn into bone cells quickly and efficiently, using high-frequency sound waves.
Synthetic mouse embryos created from stem cells - without sperm, eggs, or a uterus
it from below by the microscope's soft glow, the translucent mouse embryos looked exactly as they should. On day 3 they began to elongate, from spheres into cylinders. On one end, the neural tube started to fold around day 6, on the other a tail began to bud.
Study links 'stuck' stem cells to hair turning gray
Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.
Biotech Company Says It's Implanted Dopamine-Making Cells in Patients' Brains
A California-based biotech company says it has successfully implanted lab-made neurons in Parkinson's patients' brains to stimulate dopamine.
