Stem Cell Therapy Regenerates Heart Muscle In Heart Attack Patients

...f embryonic stem cells that are derived from human embryos that have been discarded for reproductive purposes. As these cells are in primitive stages of cell development, placement of these cells from a donor to a recipient is not associated with an immune trigger. These cells can therefore be transplanted...

Neurological Damage Can Be Reduced By Stem Cell Transplants

...o mentioned that by not taking the stem cells from embryos or foetuses, they have avoided the ethical and political issues it could cause. The researchers also saw about a 25 percent improvement in treated rats affected with a condition equivalent to human cerebral palsy. But, the researchers only observe...

Gender Question Solved

...rivative of Vitamin A, causes germ cells in female embryos to begin meiosis, leading to the production of egg... In the case of males an enzyme is present in male embryos that wipes out retinoic acid and so suppresses meiosis before birth, resulting in sperm production. ...

Fertility Treatment Can Be Affected By The Use Of Marijuana

... of eggs that could be retrieved and the number of embryos that could be transferred. Women who smoked marijuana during the year before the procedure had 25% fewer eggs and about one fewer embryo transferred, when compared with women who didn't smoke during that year, the researchers noted. Similarly, it was...

British fertility clinics have low success rates

...alled foetal reduction. In this procedure when two embryos are implanted in the woman’s womb in the hope that at least one of them will implant then if both develop, one of the twins is destroyed in order to increase the growth potential of the other. This procedure is considered as unethical by many docto...

Huntington's sufferers have reason to cheer: sufferings might have an end!!!

...al neuroblasts and neural precursors obtained from embryos after elective abortion. In the words of the authors, 'The future therapeutic strategy against the disease probably relies on a combination of principles, neuroprotection, and neuronal replacement. Neuro-protection could stop the disease, but only...

Hwang Woo Suk Suspended By Seoul National University

...ey had produced a stem cell line taken from cloned embryos and to have produced individually tailored stem cells. Both studies were published in the journal Science in 2004 and 2005.The university's investigations found in January that the results of this research had been falsified. Hwang handed in his resi...

Designer Babies- To Create Or Not To Create!

... dignity of the created child and discarding other embryos unfit for the primary purpose do exist. The long-term health consequences of children born through pre-implantation genetic diagnosis (PGD), has also to be borne in mind. More research is clearly indicated to monitor the development of such children....

Female Foetus Can Survive More Stress

...ies under stress have less tolerance for unhealthy embryos and foetuses and thus spontaneously abort the offspring that would have been otherwise carried to birth. Writing in Proceedings of the National Academy of Sciences of the US, researchers concluded aborting boys might be a way to maximize the odds o...

Hwang Woo-Suk Apologizes For Fabricating Research

...tigating Hwang concluded he had never cloned human embryos and had purposively fabricated results for two landmark papers published in the Science journal. Hwang, 53, said he would take full responsibility for the fabrication of the research papers and admitted to exaggerating the data published in Science...

Treating Sickle Cell Anemia using Healthy Stem Cells

...in bioengineered mice with healthy stem cells from embryos leading to replacement of defective genes, after therapy it was found that the replaced healthy genes produces non-defective healthy hemoglobin. The researchers have published their work in the Journal Proceedings of the National Academy of Sciences....

Stem Cell Research - Changing Wishes to Possibilities and Possibilities to Reality

...cell harvest, and the possibility of cloning human embryos for research are a few of the ethical considerations to be tackled before initiating stem cell research on a large scale. Even though stem cell experiments conducted on animal models show much hope and promise in miracle cures, extreme caution has ...

Little Known DNA Repair Enzyme May Be A Tumor Suppressor Gene

...All the same, fibroblasts were isolated from these embryos to see if they could be kept alive in culture. After repeated attempts, the mouse embryonic fibroblasts, or MEFs, failed to divide and died within a few weeks or months. Suspecting that the MEFs died because they were self-destructing, or undergoi...

Genetic mystery behind muscle development unraveled.

...Similar experiments carried out in developing frog embryos confirmed their finding. Increasing miR-1 caused more muscle tissue overall and fewer myoblasts, while increasing miR-133 led to more myoblasts but less muscle overall in the frog embryo. "That was quite a surprise to many people because those two ...

Mice With Human Thought Processes Could Be Developed In The Future

...een formulated to prevent the development of human embryos inside experimental animals. Though the above study was conducted before the formulation of these guidelines, an ethical clearance was obtained before initiation of the study. This novel finding can help scientists better understand the fundamental...

Heart Stem Cells Could Revolutionize Cardiac Disease Therapy

...the current study, researchers used Drosophila fly embryos as the model and identified that a miRNA called miR-1 was responsible for the formation of stem cells that ultimately gave rise to the heart. "miR-1 interferes with expression of a crucial gene that controls whether or not certain progenitor stem cel...

Scientist Calls Upon Media To Retract His Work

...oh, the first stem cells removed from cloned human embryos and, therefore, tailored to specific patients. The most recent research was especially hailed as offering potential breakthroughs for incurable diseases like Parkinson's and Alzheimer's disease and diabetes in which replacement cells could be geneti...
