Pluripotent stem cells used for regenrative medicine risks. They can develop mutations that favor the production of cancer cells

It should be crucial to check pluripotent cell lines (embryonic and iPS cells) before clinical testing before their use in regenerative medicine The production of pluripotent stem cells, from which virtually all types of cells can be obtained, may be of great use for the...

Intestinal tissue produced from embryonic stem cells and iPS cells

The intestinal nervous system controls several functions of the gastrointestinal tract, and when impaired causes bowel abnormalities. Now, a group of American researchers has generated intestinal tissue from embryonic and iPS cells (this last hasn’t ethics problems), using...

Patient’s own menstrual blood stem cells used to treat Asherman’s syndrome

Infertility treatment.”The best option for endometrial regeneration in patients with Asherman’s syndrome.” Asherman’s syndrome is an acquired uterine abnormality characterised by the presence of intrauterine adhesions, and which clinically causes...

Embryonic stem cells treatment is used to treat spinal cord injury with apparent success

Doctors are careful not to predict Boesen’s future progress Keck Medical Centre of the University of Southern California (USC, United States) announced that a team of doctors from the Center became the first in California to inject an experimental treatment made from stem...

Bone marrow stem cells for the treatment of multiple sclerosis. Surprising results

A recent study published in the The Lancet has shown surprising results as regards the use of autologous bone marrow stem cells for the treatment of multiple sclerosis. The study included 24 patients, 1 of whom died, while the remaining 23 had an objective improvement, with 69.6%...

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...

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...

Clinical trials using embryonic stem cells authorised in the United States

Clinical trials using embryonic stem cells which, as we know, requires the destruction of human embryos, is approved The North American FDA has given its approval to the Californian company Asterias Biotherapeutics to begin a clinical trial at the beginning of 2015. The aim of...

Embryonic stem cells in regenerative medicine

A major issue associated to the use of embryonic stem cells in regenerative medicine is their tendency to induce tumour formation in the transplant receiver due to their undifferentiated state. This does not seem to happen when adult cells are used, however. In a recent letter...

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...
