Pharmaceutical and biotech biggest companies open their labs to a veterinary inspector

Animals testing ethics. A recently published interview successfully addresses the antagonism between animal welfare and the undeniable need for animals for biomedical research. We quote the article published by Stats that affirms “Some cities have public advocates. Others...

In vivo cell reprogramming. A major step forward in regenerative medicine

Cell reprogramming  is revolutionizing the biomedical world, not only because it can obtain cells of different tissues from pluripotent cells, but also because these cells can be genetically modified to be used for the treatment of serious illnesses or to better understand them,...

Human-mouse hybrids created with sperm produced from human testicular stem cells

According to a recent article (see HERE), a team of researchers has managed to produce human functional spermatids (as sperm precursor cells are known) from human spermatogonial stem cells (SSC), testicular sperm cell precursors.  The SSCs were isolated and identified...

A step to a cancer vaccine. A promising animal trial with autologous iPS cells

 Cancer vaccine advances A new possible use of iPS cells (see medical and ethical advantages of iPS cells treatment) has been opened up, using them as a type of vaccine against cancer. According to a recent study published in journal CELL (see HERE), autologous iPS cells (i.e....

Functionally active artificial ovary produced in rats

Anti-cancer therapy or advanced age in women can lead to loss of ovarian function (see HERE new positive advances). Cancer therapy effects cause objective health problems, such as sexual changes, obesity and osteoporosis. These changes can be alleviated by hormone replacement...

Cells from human umbilical cord blood revitalized part of aged rats’ brain

Cord blood stem cells revitalized part of the brain in aged rats. Umbilical cord blood is known to contain stem cells that can be used for different clinical objectives  (see HERE), especially in the promotion of cell banks. Now, a new possibility for the use of umbilical cord...

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...

Retinal tissue produced from iPS cells in animals

One of the possible applications of iPS cells is in the treatment of retinal diseases. Now, a group of researchers from the Riken Institute in Kobe (Japan) see HERE has presented some interesting experiments in which they were able to produce retinal tissue from iPS cells (iPS...

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...

Producing human organs in animal chimeras raises objective medical and ethical problems

The major medical and social problems in organ transplantation owing to the increasing shortage of donor organs is well known. Solutions must therefore be sought in the fairly near future that can resolve these issues. One of these is the production of animal chimeras in which...
