It is generally agreed that adult heart muscle cells (cardiomyocytes) cannot regenerate after an ischemic attack. However, Cui et al. (read HERE) in an experimental study in mice (read our articles on heart treatments in animals), found that their cardiomyocytes [...]
An experimental study in mice has found that the heart is formed in the fetus earlier than previously believed since it is thought that in humans, it begins to beat at 21 days of life. Now a team funded by [...]
On 15 November last year, an article was published in the prestigious journal Science, which assessed the development of monkey embryos after their implantation in the uterus. Since mammalian embryos develop after implantation in the uterus, direct observation of their [...]
Israeli researchers have used the CRISPR gene-editing tool – read our special report on the issue – to obtain single-sex offspring in mice. In their article published in EMBO reports, the scientists managed to obtain almost exclusively female offspring from [...]
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 have consumer [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
