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)...

Tissues and organs production using 3D printing: a hopeful but distant possibility

A topic that has major ethical connotations is tissues and organs production using the innovative 3D printing technique. A recent article in The Lancet discusses some of its possibilities, such as in maxillo-facial surgery, production of vascularised tissues, especially tubal...

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...

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...

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...
