Intestinal tissue produced from embryonic stem cells and iPS cells

The intestinal nervous system controls several functions of the gastrointestinal tract, and when impaired causes bowel abnormalities. Now, a group of American researchers has generated intestinal tissue from embryonic and iPS cells (this last hasn’t ethics problems), using...

Serotonin produced from neurons obtained with iPS and embryonic stem cells

Serotonin is implicated in functions as important as humour, sadness, feelings of aggression, anxiety and sleep disturbances, among others. A deficiency in serotonin release has been related with schizophrenia, depression, bipolar disorder, obsessive-compulsive disorders, chronic...

Cerebral organoids produced from embryonic stem cells

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 foetuses with the same...

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...

What is the current clinical usefulness of stem cell treatments, embryonic and iPS cells?

Human adult stem cells (iPS) have been found to be the most clinically useful human cells for therapeutic purposes Pluripotent cells (iPS) are defined as those from which cells of different tissue types can be obtained. These can be obtained either from preimplantation human...

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...

Clinical trials using embryonic stem cells authorised in the United States

Clinical trials using embryonic stem cells which, as we know, requires the destruction of human embryos, is approved The North American FDA has given its approval to the Californian company Asterias Biotherapeutics to begin a clinical trial at the beginning of 2015. The aim of...

Can human iPS cells replace the use of human embryonic stem cells?

A hotly debated topic within the specialised scientific world is whether or not human iPS cells are similar to human embryonic cells, which raise too so many ethical issues. It is a mistake to believe that this, in principle, is a problem with exclusively technical implications,...

Stem cell therapy by cardiomyocytes derivied from embryonic cells

Objectives ethical difficulties Stem cell therapy: Functional cardiomyocytes can be derived from pluripotent stem cells, and thus be used to repair damaged hearts. There are numerous experiments in this field. These cells have been specially derived from human embryos (embryonic...

Is it morally licit to use cell lines obtained from currently stored embryonic stem cells?

One of our colleagues, a doctor in Molecular Biology who is currently conducting post-doctoral research in the United States, mentioned to us that he had “recently discovered that the cells with which he was working come from human embryos, the famous HEK-293 cells”....
