Promising new treatment of spinal cord injuries presents bioethical problems should be resolved

Spinal cord injuries are one of the pathologies that present the greatest medical issues in regenrative medicine. Thus, their possible treatment with stem cells has meant—and means—one of the major challenges for regenerative and reparatory medicine. Nevertheless, progress in...

Human fetal tissue debate erupted again. The Trump administration restricts the use of fetal tissues

Moral, and ethical considerations The Trump administration is limiting the use of fetal tissues obtained from elective abortions for biomedical research. Should the government pay for medical research that uses tissue from aborted fetuses? Can human tissue be used as an object of...

In vivo cell reprogramming. A major step forward in regenerative medicine

Cell reprogramming  is revolutionizing the biomedical world, not only because it can obtain cells of different tissues from pluripotent cells, but also because these cells can be genetically modified to be used for the treatment of serious illnesses or to better understand them,...

Nature changes its policy allowing experimentation with human embryos. Why?

Nature Group does not explain the reasons for this change. In any case, the question remains if its decision is based on new scientific evidence. Research using human embryos and embryonic stem cells has prompted a fierce ethical debate. As editors of these types of studies, the...

Human embryos research and the Politics of Bioethics

Ethical objective questions posed by human embryo experimentation are exacerbated by the deregulate gene editing techniques research including biohackers A book has been published by Columbia University, entitled “Experiments in Democracy. Human Embryo Research and the Politics...

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...

New clinical celular trial for treatment of Parkinson’s disease injecting stemcells in the patient brain

A first step to a Parkinson treatment with stem cells. The first clinical trial conducted in China (see HERE) to treat Parkinson’s disease and age-related macular degeneration and the second most common neurodegenerative disorder is to be launched shortly. In the next few...

The biological status of the early human embryo. When does human life begin?

“Those who argue that that embryo can be destroyed with impunity will have to prove that this newly created life is not human. And no-one, to the best of our knowledge, has yet been able to do so.” Introduction In order to determine the nature of the human embryo, we need to know...
