It is not a rhetorical question, but in order to understand this phenomenon we must understand the nature of cells and how they work. The distinction between stem cells and others is that these cells are capable of renovating themselves after a period of inactivity, also they can be stimulated to become organ-specific cells with special functions.

Nowadays scientists subdivide such cells into four types: And the last type is the adult stem cells used to replace cells that have died or lost it functions, it is undifferentiated cells present in differentiated tissue.

For the reason that types and function of stem cells are discovered, scientist are working towards creating new methods of stem cells usage in medicine, spending billions of dollars in the attempts. First of them is the way of using genes stem cells in order to make people stronger, healthier and even more mentally alert.

And the second one is the mode of treating fatal illnesses using replacement diseased cells by healthy genes.

To be or not to be a white blood cell, that is the question

But even endeavors to realize these methods were met with the resentment. Why being on the verge of one of the greatest science discoveries brings people into the frustration? Another widespread belief is that science borders on cloning people, what could become the nightmare for the mankind.

Meanwhile strenuous efforts are under way to stimulate development of this field.

But will the society accept such way of treating as stem cells? Probably not in the foreseeable future.Some preliminary clinical trials achieved only modest improvements in heart function following use of bone marrow stem cell therapy.

Stem-cell therapy for treatment of myocardial infarction usually makes use of autologous bone marrow stem cells, but other types of adult stem cells may be used, such as adipose-derived stem cells.

Stem cell therapy is the use of stem cells to treat or prevent a disease or condition. Bone marrow transplant is a form of stem cell therapy that has been used for many years without controversy.

Advantages. Stem cell treatments may lower symptoms of the disease or condition that is being treated.

Nov 16,  · Researchers hope stem cells will one day be effective in the treatment of many medical conditions and diseases. But unproven stem cell treatments can be . As stem cells renew themselves and can become different kinds of cells, they might become cancer cells and form tumors.

Stem cells grown in the laboratory, or adult cells reprogrammed to be stem. The unexpected finding that autologous induced pluripotent stem cell (iPSC)-derived teratomas are immunogenic in syngeneic hosts sparked pessimism over their therapeutic potential; however, two recent reports (Guha et al., and Araki et al., ; the latter in this issue of Cell Stem Cell) contradict previous findings, showing no immunogenicity of in vitro differentiated syngeneic iPS.

When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.
