Cryopreserve ovarian tissue from prepubertal girls who are to undergo cancer treatment. Medical and ethical approach

When a cancer patient is treated with radio and/or chemotherapy, they can become infertile, both men and women. Consequently, ovarian tissue cryopreservation prior to treatment is recommended in women, with the cryopreserved tissue then transferred again to the patient if she...

Ears made in China, using 3D printing technique, are implanted in 5 children

A team of Chinese scientists has been able to implant ears created using an experimental technology that combines cultured patient’s cells with 3D printing in five children. The children suffered from microtia, a congenital external ear deformity that affects one in every...

3D artificial ovary constructed with excellent results. New hope for women infertility

A team of researchers from the McCormick School of Engineering at Northwestern University in the United States has reported that it has managed to construct the structure of an artificial ovary 3D  (see HERE) a hydrogel that, once transplanted in an animal, can interact with its...

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...

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...
