IPSC: The future of stem cells

2019-01-18T20:54:58+01:0011 January 2019|Categories: No Category|Tags: , , , |

Imagine every cell in our body as a potential stem cell! Sounds like science fiction, instead it is reality thanks to the studies of Kazutoshi Takahashi and Shinya Yamanaka, that in the 2006 have shown that it is possible to reprogram a somatic cell (it is. epithelial cell) bringing it back to a stage of stemness. These reprogrammed cells, thanks to the artificial insertion of 4 stamina cells, they were called iPSCs or “Induced Pluripotent Stem Cells”. First of all we need to take a step back and ask ourselves what a stem cell is. It is a cell that has the ability to transform into other cells in the body through a mechanism called "differentiation". [...]

Stem cells have been at the center of a wide debate that involves not only the scientific field for some time now, but also the religious one, ethical, legal and political. Since in 1960 McCulloch and Till discovered the existence of stem cells in the bone marrow1, that is, a semi-solid tissue present within the bones of the body, they have become part of our life, arousing curiosity and interest, but also fear and skepticism. Figure 1. Why stem cells are important (edited and translated from europarl.europa.eu - European Parliament) The enormous potential of stem cells, che ha condotto numerosi ricercatori ad [...]

Stamina cells: a hope for the future

We often hear about stem cells and how they are widely used in the research world. In fact, these represent great hope in the field of regenerative medicine, but what are they really? How they are generated? Stem cells are undifferentiated cells capable of unlimited dividing and differentiating into other cell types: nervous, bone, of the heart, of the skin, liver and pancreas. Possono essere prelevate dall'embrione, dal feto o dall'adulto e a seconda della potenzialità delle cellule staminali, are classified in: totipotenti, if they give rise to a whole organism; pluripotent, if they generate many types of fabrics but [...]
