Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells—ectoderm, endoderm and mesoderm (see induced pluripotent stem cells)—but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.
There are three known accessible sources of autologous adult stem cells in humans:
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

There is considerable excitement about the use of stem cells for cardiovascular disease. Stem cells are unspecialized cells with the unique property to self-renew or make copies of themselves and to differentiate into specialized cells. The goal of stem cell therapy is to enhance the body's natural process of regeneration. There are a considerable number of stem cells currently under investigation for patients with heart attacks, angina, heart failure, and peripheral arterial disease. We have made considerable progress but have many questions left to answer. Timothy Henry, MD, FACC, is Chief of Cardiology at Cedars Sinai Heart Institute in Los Angeles, California.

Savage hypocrisy is rampant within the medical industrial complex. Through generations of supressing/diluting knowledge and racist hatred for the Goyim(Gentile, livestock), it is believed that we do not deserve basic rights, nor do we deserve to know about the potential of the stem cell miracle(or anything else for that matter). The Hermetic tradition of secrecy, narcissistic, racist, greedy, and corrupted principles need to come to an end if we are to survive and prosper in the near and immediate future.

Stem Cells are much more powerful and important than you are lead to believe. Savage hypocrisy is rampant within the medical industrial complex. The Hermetic tradition of secrecy, narcissistic, racist, greedy, and corrupted principles need to come to an end if we are to survive and prosper in the near and immediate future. I would like to take this opportunity to mention that the tradition of silence is attributed to one of the four pillars of Solomon's Temple. It had often been proclaimed that silence is might. This is undoubtedly true to some extent, especially in regards to an alchemist and magician's ascent, however this is no longer appropriate nor acceptable. Known as somatic stem cells, they can be found in children, as well as adults. Research into somatic stem cells has been ...
The third instalment of RTÉ's documentary series, 'Science Friction' where science and society collide, explores one of the most controversial issues in the history of science: the human embryo and its use in the ground-breaking field of stem cell research. In this episode, presenter Liz Bonnin embarks on a journey to meet the different people, both within and outside the science community, whose lives are touched by the controversy surrounding the embryo. Liz talks to 22-year-old Geoff Harte, who was left paralysed after breaking his neck in a school rugby match, and now believes that stem cells may one day help him to walk again. We also hear from Stephen Sullivan, a Harvard based Irish scientist who uses frozen embryos left over as a result of IVF treatment, as a source of stem cell...

Science Documentary: Stem Cells,Regenerative Medicine,Artificial Heart,a future medicine documentary In each and every one of our organs and tissue, we have stem cells. These stem cells can develop into many different kinds of cells. They can continue to divide in order to replace damaged cell tissue. As we grow older, we loose some of our stem cells, as well as the ability of those stem cells to repair organs and tissue. The function and ability of the stem cells varies greatly between men and women. Each stem cell can become a specific type of cell that has its own function, or it can remain a stem cell. The two main differences between normal cells and stem cells are that stem cells have the potential for self renewal. The second difference is that stem cells can be manipulated ...
