Pluripotent stem cells used for regenrative medicine risks. They can develop mutations that favor the production of cancer cells

It should be crucial to check pluripotent cell lines (embryonic and iPS cells) before clinical testing before their use in regenerative medicine The production of pluripotent stem cells, from which virtually all types of cells can be obtained, may be of great use for the...

The future of iPS – induced pluripotent stem cells. New finding increases tremendously their potential for clinical use

Cells now can be obtained from anonymous donors, however, and stored in a cell bank, the costs would be reduced significantly, and their potential for clinical use would increase tremendously A recent article published in Nature discussed some specific aspects regarding the...

Embryonic stem cells treatment is used to treat spinal cord injury with apparent success

Doctors are careful not to predict Boesen’s future progress Keck Medical Centre of the University of Southern California (USC, United States) announced that a team of doctors from the Center became the first in California to inject an experimental treatment made from stem...

Adult stem cells could effectively substitute embryonic cells in regenerative medicine

Many technics showed that adult stem cells could effectively substitute embryonic cells in cellular therapy. One medical and ethical problem to resolve is to find adequate substitute for the use of embryonic stem cells in regenerative and reparatory medicine. The best possibility...

Spinal cord regeneration – a step forward

Spinal cord regeneration. There is a casuistry in each patient who suffers a spinal cord injury, because a combined therapy that is successful in one patient is not transferrable to the rest. This week, both the national and international press have reported on an article in...

Parthenogenesis. A new possibility for regenerative medicine and a new bioethical dilemma

Parthenogenesis have allowed pluripotent stem cells to be obtained from oocytes (eggs) which have been stimulated to divide without having been fertilised by sperm. Can individuals be obtained from parthenogenesis? What is a partenote? Introduction A recent sentence from the...
