An article recently published in the journal Cell, raises the need to assign a legal status to new embryonic models – human embryos – obtained from pluripotent cells, coming from embryonic cells (human Embryonic Stem Cells (HESCs) or from reprogrammed [...]
Scientists from Cincinnati (Ohio) have developed the most complex stomach organoids to date, using embryonic stem cells. The biology of tissues and organs is difficult to study in mammals, especially in humans. However, advances in stem cell culture have made [...]
A group of researchers in La Jolla, California, have produced three-dimensional cerebral organoids (“mini-brains”) from human embryonic stem cells, later comparing the functionality of the tissue produced with samples of brain tissue from human fetuses with the same degree of [...]
The first trials were carried out twenty years ago, in animals with stem cells in the heart the latest experimentation with satisfactory results in mice was made last year (read HERE). The aim has been to regenerate lost heart muscle [...]
Surgical abortion The priority of healthcare systems has been to use all their resources to treat coronavirus patients and to postpone all non-urgent surgeries. In this respect, surgical abortion is considered a non-urgent intervention; indeed, some argue that it is [...]
An article published in Nature, signed by notable personalities in the area of bioethics, discusses the ethical implications of embryoids (organoids) or embryo models, in vitro cell aggregates that model various regions of the embryo to allow their study. These [...]
The President of the United States, Donald Trump, has taken a new step in the fight against abortion, announcing the end of research with tissues from aborted fetuses in federal (NIH, National Institutes of Health) laboratories. While this does not [...]
As we published recently (read HERE), the American Administration has placed restrictions on research using fetal tissue, giving rise to a fierce debate among researchers. In this respect, Judd Deere, deputy White House press secretary told Science that enacting the new [...]
Spinal cord injuries are the pathologies that present medical problems in regenerative medicine. Thus, their possible treatment with stem cells has been one of the major challenges for regenerative and reparatory medicine. Nevertheless, progress in this medical field has been [...]
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 [...]
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 [...]
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 [...]
