Scientists have now shown that skin cells can be coaxed to behave like muscle cells and muscle cells like skin cells.
The fickleness of the cells, and the relative ease with which they make the switch, provide a glimpse into the genetic reprogramming that must occur for a cell to become something it’s not.
“We’d all like to understand what happens inside the black box (cell),” said Helen Blau, professor and member of Stanford University‘s Stem Cell Biology and Regenerative Medicine Institute and co-author of a new study on the subject.
Harnessing these genetic makeovers will allow scientists to better

Embryonic stem cells (ESC) can survive even when inserted into chains of polymers, in a process in which they are “weaved” into artificial and flexible tissues able to adapt to various types of transplants. In an innovative technique, stem cells could be used in the future to produce artificial organs, say researchers at University College London.
The technique was described in a study, published in Integrative Biology. It implements other research to shape living cells into engineered tissues, including a technique which would print a live tissue using an ink printer, which would substitute normal ink

Culturing stem cells to use to treat certain illnesses is already a reality. In Spain, two labs have received authorization from the Agencia Espanola de Medicamento y Productos Sanitarios to produce stem cells, and there are others waiting to be certified.
Currently, just one public health center, the Gregorio Maranon Hospital in Madrid (HGM) and one private center, the Clinica Universitaria in Navarra (CUN) have undergone the rigid system of quality certification to become “Good Manufacturing Regulations” (GMR) laboratories and are developing stem cell products to be administered and transplanted into
At the San Timoteo Hospital in Termoli-Larino (Molise, a small region in south central Italy, formerly part of the region “Abruzzi e Molise”) everything is ready for stem cells gathering – in conjunction with the orthopedy ward (branch of medicine dealing with diseases of the bones and joints) – which will be used for local treatments, above all on pseudo-arthrosis.
Joseph Wagner sees most cell-therapy companies offering little more than a bag of cells.
His company will give the bag a little direction.
Cell Targeting is developing technology that can point stem cell therapies to specific areas of the body. Among the many challenges in cell therapy is direction: not enough of the stem cells are getting to the tissues that needs treatment (…)
Currently a stem cell therapy can help different parts of the body. That attracts more customers, but doesn’t do much when the company wants to differentiate its product and charge a different price.
