Cerebral organoids produced from embryonic stem cells

A group of researchers in La Jolla, California, have produced three-dimensional  cerebral organoids (“mini-brains”) from human embryonic stem cells, later comparing the functionality of the tissue produced with samples of brain tissue from human foetuses with the same...

Public funds authorised for production of human-animal chimeras

In September 2005, the dedication of public financial aid by the National Health Institutes for experiments on transferring human stem cells to animal embryos to produce chimeras was banned. However, on 4 August this year, this ban was lifted for certain experiments, and it was...

Potential application of organoids that mimic different organs

In 2011, almost incidentally, Madeline Lancaster of the Institute of Molecular Biotechnology in Vienna managed to produce primitive retina cells and different nerve cells from embryonic stem cells. However, Lancaster and her colleagues were not the first to produce a brain...

Stem cells and the production of organoids at the forefront of biomedical science

There are topics in which biomedical interest merges with ethical interest. One of these is undoubtedly the subject of stem cells wich appears to be the biomedical science forefront. Few issues in the biomedical sciences arouse as much interest as these, and for this reason, the...

Brain tissue repair advances. Human nerve cells derived from astrocytes

Within the possibility of deriving cells from others already existing in our body, in the area of cell therapy, scientists have managed to reprogram brain astrocytes into neurons in the way to achieve brain tissue reapair. As we know, neuronal loss is thought to be definitive in...

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...

Improved efficacy in the generation of iPS cells for clinical use

One of the difficulties in the use of reprogrammed cells (iPS cells) is the low efficiency. Now, a technical step has been taken to substantially increase this. Using it, Australian researchers, combining it with the genome editing technique CRISPR-Cas9, have been able to...

iPS cells derived from HIV-resistant individuals for the treatment of HIV infection

New technique: It involves iPS cells from HIV-resistant individuals for the treatment of people infected  Some people have a mutation in their genome (CCR5A32) that gives them certain resistance to HIV infection. Taking advantage of this situation, a step has now been taken that...

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...

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,...
