3D bioprinting for regenerative medicine and to produce organs. State of the art and an ethical reflection

A recent article published in the Journal of Stomatology, Oral and Maxillofacial Surgery (Volume 120, Issue 2, April 2019, Pages 128-132) made a great review with the suggestive title 3D Bioprinting: principles, fantasies and prospects. It is based on a PubMed/MEDLINE search that...

FDA wins major victory in campaign against stem cell clinics that marketing bogus and potentially hazardous products

One bioethical issue our Observatory is following is the proliferation of clinics offering stem cell treatments, many of which do not meet the necessary quality requirements. We published our first article on this problem in 2017 (see HERE and also North America’s two cell...

Can brain damage be repaired using cell reprogramming? Can be replaced the neurons?

Cell reprogramming (read our report about this technique HERE) has opened great therapeutic possibilities in medicine. Within this field, one of the most attractive possibilities would be to replace neurons that may be destroyed in various illnesses or following a stroke. Now, a...

Cell life extended, authors suggest that this finding could increase human life expectancy

Building on two decades of research, investigators at UT Southwestern medical school have determined that “cellular housekeeping” (all cells and code for proteins that are essential for basic cell growth and metabolism)  can extend the lifespan and improve the health...

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...

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...

Transplant of cryopreserved ovarian tissue to leukemia surivivor women. A healthy child have already been born

First child healthy born from a leukemia cancer survivor More than 80 children have already been born worldwide after cryopreserved ovarian tissue-transplantation in women who, due to disease or medical treatment, could lose the chance to have children in the future. Over the...

For now, iPS cells have revolutionized the laboratory bench more than bedside

In a recent article, Amélie Rezza discussed the current use of iPS cells, understanding as such adult cells reprogrammed following a technique discovered by Yamanaka. See HERE our site for furthermore information. After the development of these cells, it was thought that they...

Therapeutic potential of Cas9-based epigenetic gene activation is proved in mice. VIDEO

 The Belmonte lab’s advanced in vivo Cas9-based epigenetic gene activation system in mice Salk scientists have created a new version technique of the CRISPR/Cas9 genome editing technology that allows them to activate genes without creating breaks in the DNA, potentially...
