Pulmonary organoids produced from human iPS cells in three dimensions (3D)

Lung organoids have been produced from human pluripotent stem (iPS) cells that contain various components of lung tissue, and even airways and alveolar structures (see HERE). Recapitulation of lung development from human pluripotent stem cells (hPSCs) in three dimensions (3D)...

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...

Retinal tissue produced from iPS cells in animals

One of the possible applications of iPS cells is in the treatment of retinal diseases. Now, a group of researchers from the Riken Institute in Kobe (Japan) see HERE has presented some interesting experiments in which they were able to produce retinal tissue from iPS cells (iPS...

Regenerative medicine. A review of current findings from an ethical perspective

The field of action of regenerative medicine (RM) is growing daily. Indeed, we only have to look at the economic figures that it moves, with an estimated market value for 2020 of 61,000 million Euros. However, RM also has important ethical components, not only related with the...

Umbilical cord blood banks. What is the ideal type?

Since umbilical cord blood banks were first used for stem cell transplants, their number has been increasing permanently worldwide. There are currently three types of umbilical cord blood banks: public, private and mixed. In the public banks, samples are at the disposal of any...

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...

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,...

iPS cells an ethical end effective technique for medical purposes

Now, for the first time, skeletal muscle cells have been derived from iPS successfully A concern raised some time ago is to determine whether the iPS cells produced from adult somatic cells have the specific characteristics of embryonic stem cells. If so, iPS cells could...

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...

Cell therapy clinics unregulated in the United States

For years, American “stem-cell tourists” have flocked to unregulated clinics in Mexico, the Caribbean and China in search of everything from heart treatments to facelifts. But now, these kinds of clinics are popping up across the United States (The Washington Post,...
