Stem Cells From Sperm Offers New Treatment For Male Infertility

Most people only hear of embryonic, fetal, cord blood stem cells, or bone marrow stem cells.  Stem cells are actually produced throughout the body.  One interesting place that stem cells are very prolific, and makes the most sense concerning the beginning of life, is the male testes (i.e. sperm stem cells).

Here is a medical research paper written by Hideyuki Kobayashi, Koichi Nakajima, Shuichi Kamimura, Koichi Nagao and Nobuhisa Ishii at the Toho School of Medicine in Tokyo, Japan.  Here is a small portion of the research paper:

“Continuation of the spermatogenic process throughout life relies on proper regulation of selfrenewal and differentiation in spermatogonial stem cells. Mouse spermatogonial stem cells can be cultured with established methods; however, human spermatogonial stem cells are not well understood. Recent reports have shown that adult cells can be reprogrammed to pluripotency if specific genes are delivered and almost established assay. These cells are called iPS (induced pluripotent stem) cells. In addition, it has been reported that pluripotent stem cells can be generated from adult human testes. Stem cell science has progressed remarkably quickly over the last 5 years. Future research into stem cells may reveal the mechanisms underlying male infertility and allow for patient-specific treatments. In this review, we provide an overview of the current understanding of human spermatogonial stem cells and pluripotent stem cells from adult human testes.”

In the paper titled “Human Spermatogonial Stem Cells and Pluripotent Stem Cells from Adult Human Testesno access,”  The Toho medical group reveal a possible new breakthrough in understanding male infertility and  offering treatment that is patient specific.


Stem Cells for Dogs

Just when you thought you have heard everything, something new has popped into the scene.  Stem cell therapy for you pet.  While this may sound wacky, this really is an amazing lifesaver to many animals.  Often even saving the owner money in the long run. If you own a pet, then you know that many … Continue reading

How to Handle Potential Infections in Stem Cell Research

Anytime you are dealing with human or animal tissue, there is the danger of infection or the spreading of disease. In Spain they have been working on this issue for years and there is a paper by Fernando Cobo of the Stem Cell Bank of Andalucía in which he addresses this issue. Here is a … Continue reading

Stem Cells that Live Forever… from Human Hair

Here is a quick overview from a group of scientists in Massachusetts (Beth Israel Deaconess Medical Center and University of Mass Medical School) explaining how they were able to derive “immortal” stem cells from human hair follicles: _____________________________________ Multi-potentiality of a new immortalized epithelial stem cell line derived from human hair follicles By: Cecilia Roha, … Continue reading

Natural Sources of Stem Cells In Our Body

Stem cells reside in all areas of the body.  At one time, scientists believed that stem cells only resided in the bone marrow.  Science has taught us differently now. Stem cells reside in the skin.  The stem cells here are responsible for holding off the signs of aging and damage.  Let’s face it, we all … Continue reading

Increasing Stem Cell Production

Many people ask why we even need stem cells for regeneration.  After all, if stem cells are being harvested from the human body for therapy, why are our own stem cells not working to ward off disease or aging? This is a very good question.  Everyone assumes that a stem cell is a perfect cell, … Continue reading

Stem Cell Research Pros

Stem cell research pros has shown us that stem cells are special cells which, when given specialized signal, can become any part of the body needed for regeneration.  The body may need muscle cells, blood cells, skin cells, organ cells, nervous system cells, etc.  The stem cells will go in and sweep up the cells … Continue reading

Stem Cell Therapy – Quackery or Truth?

People find that many new therapies promoted in the press or by their doctors as the next great silver bullet, does not live up to the hype and may be downright quackery. These sensationalist claims are intended to pull more money out of your wallet with the promise of the next biggest and greatest invention … Continue reading

Breast Cell Found To Have Stem Cell Like Capabilities Of Producing Cancer

Stem cell – like cells can be turned cancerous in breast tissue.  Researchers from Michigan State University characterized two types of breast epithelial cell types, with one type possessing the ability to become mutinous under certain conditions because these particular cells exhibit stem cell-like characteristics that can turn into breast cancer. The epithelial cells make … Continue reading

Amnionic Fluid-Another Source For Stem Cells

Fetal stem cells have been another source of controversy through the years.  Some people disagree with using a fetus for stem cell research.  Several factors are involved in the controversy.  Aborted fetuses, via abortion, were used at one time for a source of fetal stem cells.  Unplanned miscarriages are another source.  These avenues evokes many … Continue reading
