Scientists with 3D – bioink technique print a cornea that mimic human ones. Great hope to patients waiting for cornea donation

Science Daily published an article with the title, 3D printed artificial corneas similar to human ones, we extract the following text, “When a person has a severely damaged cornea, a corneal transplant is required. However, there are 2,000 patients waiting for the cornea...

With the aim to find a new sources of organs for transplantation, Japan approves the first human-animal embryo experiments. Positive and negative apects

Scientist Hiromitsu Nakauchi is the first researcher in Japan to receive permission from the government to create animal embryos that contain human cells human-animal chimeras and transplant them into surrogate animals for gestation, as explained in an article in the journal...

Cardiac muscle cells, that drive the beating of the heart, developed from iPS cells

Cardiomyocytes produced with success One of the possibilities for the clinical-experimental use of iPS cells is to develop human-like tissues -organoids- for use in basic research or in preclinical therapeutic studies. Now, using iPS cells obtained from primates, a team from...

Human-sheep hybrids created for the first time to develop organs

Human-sheep hybrids have been created for the first time by scientists at Stanford University (see New advances and challenges in the production of human-animal chimeras). The scientists grew the embryos in a surrogate sheep, allowing them to gestate up to 3 weeks (see HERE )....

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)...

Reproductive medicine and the production of bioartificial organs

Reproductive medicine and the production of bioartificial organs may be a source of hope in the next few years for patients with degenerative lesions of various organs, among them the reproductive organs. Undoubtedly, in this respect, major advances in stem cell knowledge,...

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...
