According to Science Daily, Dr. Nagy, senior investigator at the Samuel Lunenfeld Research Institute of Mount Sinai Hospital, there is a «new method of generating stem cells that does not require embryos as starting points and could be used to generate cells from many adult tissues such as a patient's own skin cells.»

Whether building organs or maintaining healthy adult tissues, cells use biochemical and mechanical cues from their environment to make important decisions, such as becoming a neuron, a skin cell or a heart cell.

The research team took skin fibroblast tissue from adult mole - rats and reprogrammed the cells to revert to pluripotent stem cells.

These are cells taken from adult non-muscle tissues, such as skin or blood, and reprogrammed to revert to a primordial state.

Organlike tissue bits can be generated from pluripotent stem cells that are either plucked from embryos or created by taking a person's adult skin or blood cells and chemically inducing them to revert to an embryonic - like state.

Pluripotent stem cells include embryonic stem cells, which are derived from early embryos, and induced pluripotent stem cells, which are made by reprogramming cells taken from adult tissues such as skin.

Converting adult skin cells into pluripotent cells — immature stem cells that can be programmed to become any tissue in the body — is a rapidly developing area of science that earned the researcher who discovered the technique, Shinya Yamanaka, a Nobel Prize in 2012.

In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells, but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.

The researchers were able to «reprogram» adult skin cells to become cells of a different tissue type.

However, while hESCs are created from human embryos, iPS cells are cells that were originally from adult tissues, such as skin from an adult body, but have been «reprogrammed» to a hESC - like state.

* Adult mammals can restore other types of tissue, including bone, liver and skin tissue, but by the strictest definition — the faithful replacement of damaged or resected body parts — they can only regenerate their fingertips.

InvivoSciences makes engineered heart tissues from mouse embryonic stem cells and stem cells from differentiated adult tissues in humans, such as fat and skin.

Last year Thomson shook the field again when his lab and a Japanese team showed a way of genetically reprogramming adult skin cells to act like stem cells, including the ability to form any of the body's tissues.

In randomized experimental and data analysis protocols, MSI - 1346 has been shown to regenerate heart, connective, nerve, skin, bone and vascular tissues in adult zebrafish.

Adult stem cells serve as a reservoir of cells for repair of damaged tissue throughout the life of an individual, but the maintenance and regeneration of tissues, such as skin, liver, blood and muscle, dramatically decrease with age.

Unfortunately, the number of adult stem cells present in local areas of the body vary greatly in number and most researchers agree that there are simply not enough stem cells «at the ready» within brain tissue to heal itself in the same way the skin does after a cut.

Male and female adult worms find each other in a dog's episcleral tissues, mate and produce microfilaria that leave the orbit and travel through the skin primarily of the head and back.
