The latest technology in tissue regeneration is stem cell therapy. This technology will forever change the medical field and outcomes of treating disease. A stem cell is a cell that has the potential to regenerate tissue over a lifetime. Properties of stem cells are assessed for their ability to differentiate and self-renew. There are different origins of stem cells. Embryonic Embryonic stem cell lines are cultures of cells derived from the blastocyst or earlier stage embryos. Embryonic stem cells are pluripotent and give rise during development to all derivatives of the three primary germ layers, the ectoderm, endoderm and mesoderm. Embryonic stem cells (pluripotent) have the potential to differentiate into each of the more than 200 cell types of the human body. Once past embryonic development, pluripotent stem cells can only develop into certain cell types. Three Primary Germ Layers Are: Ectoderm: Nervous System, Skin Endoderm: Entire Gut, Lungs Mesoderm: Muscle, Bone, Blood Fetal The primitive stem cells located in the organs of fetuses are referred to as fetal stem cells. There are two types of stem cells that are referred to as fetal stem cells. Fetal proper stem cells come from the tissue of the fetus proper, and have … Continue reading →

(WMC-TV) - More than 60 percent of American households include at least one pet, and for many of us they are more like family than a four-legged friend. Eight-year-old Sadie suffers from debilitating arthritis. To owners Greg and Marsha James, she is a miracle dog. "She's my little girl, she's my baby," said owner Marsha. "I didn't know if we could do anything and what we could do, I thought we were gonna lose her." Last year she could not even walk, but a scientific breakthrough using her own stem cells put the pep back in her step. "Stem cell is used to treat chronic arthritic conditions," said Dr. Kathy Mitchener, DVM at Angel Care Center for Pets. Dr. Kathy Mitchener removed a few ounces of fat from Sadie's tummy; a lab extracted the stem cells, which were then re-injected into her trouble spots. "If there's joint destruction, if there's changes in metabolism then they change themselves and multiply to help address those issues," said Mitchener. Stem cell treatment proves to be just one of many medical miracles at the Angel Care Cancer Center for Pets in Bartlett. Take Rylee for example. The 2-year-old golden retriever has an unusual type … Continue reading →

A new study marks a step toward stem cell treatment of infertility Clouds Hill Imaging Ltd./Corbis The causes of infertility, which affects around 10% of couples, are often unknown, but may in some cases result from the body's inability to produce viable gametes also known as sperm and egg cells. The first study of the development of such 'germ cells' from humans could help scientists to learn how to create them in the laboratory instead. Even though the reproductive age for humans is around 1545 years old, the precursor cells that go on to produce human eggs or sperm are formed much earlier, when the fertilized egg grows into a tiny ball of cells in the mothers womb. This ball of cells contains pluripotent stem cells blank slates that can be programed into any type of cell in the body and researchers are hoping to use these stem cells to treat various conditions, including infertility. But little is known about the early developmental stages of human gametes owing to the sensitivity of working with human tissue and most work in this area has been conducted using mice. In a Nature Cell Biology paper today, researchers from the University of California, … Continue reading →

The Sultan bin Abdulaziz Humanitarian City (SAHC) announced Tuesday its intention to take stem cell transplantation to new heights by using the method to cure spinal cord injuries. The announcement was made by Prince Khaled bin Sultan, chairman of the Sultan bin Abdulaziz Al-Saud Foundation (SAAF), during the international spinal cord injury conference 2014, which kicked off at the SAHC headquarters on Tuesday. The theme of the conference, which ends on Thursday, is Toward a Better Quality of Life. The conference, first introduced in Australia and New Zealand, is being held for the first time in the Middle East. The technology, in collaboration with the US-based University of Miami, will revolutionize the scope of paralysis surgery in the Kingdom, making it a leader in the field. An accord on collaboration between the SAHC and the Miami Project to Cure Paralysis (MPCP), the first center in the US to receive approval from the supervisory board of the Food and Drug Administration for stem cell therapy, was also signed. Prince Khaled said that the transfer of this technology comes amid efforts to help families cope with the life-changing effects of spinal cord injuries. Prince Khaled said many people between the ages of … Continue reading →

PUBLIC RELEASE DATE: 5-Mar-2014 Contact: Shawna Williams shawna@jhmi.edu 410-955-8632 Johns Hopkins Medicine Johns Hopkins researchers say they have found one way that a recently discovered genetic mutation might cause two nasty nervous system diseases. While the affected gene may build up toxic RNA and not make enough protein, the researchers report, the root of the problem seems to be snarls of defective genetic material created at the mutation site. The research team, led by Jiou Wang, Ph.D., an assistant professor of biochemistry and molecular biology and neuroscience at the Johns Hopkins University School of Medicine, reports its finding March 5 on the journal Nature's website. Two years ago, researchers linked the gene C9orf72, named for its location on the ninth human chromosome, to amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig's disease, and to frontotemporal dementia (FTD). In ALS, motor neurons nerve cells that carry messages from the brain to muscles degenerate and eventually die, which gradually paralyzes the patient. In FTD, neurons in the frontal and temporal lobes of the brain die. Some scientists think the same genetic and biological processes cause both disorders, but with very different symptoms, depending on where in the brain they occur. The … Continue reading →

New tests could spare soldiers from debilitating sickness at high altitudes--and mitigate cattle deaths in the Rockies Chris 73, Wikimedia Commons On his 27th birthday, David Hillebrandt and his wife Sally began to climb Mount Kenya, the second-highest mountain in Africa after Kilimanjaro. Instead of gearing up and heading straight for the mountain's tallest peakwhich reaches 5,199 metersthe couple started their journey more leisurely, trekking through scenic ridges and valleys around the mountain at an altitude of about 3,000 meters. David, who today serves as a medical advisor to the British Mountaineering Council, already had considerable climbing experience at the time: he had scaled a 5,790-meter peak in Pakistan and 3,960-meter peaks in the European Alps. Sally, in contrast, had never done any serious climbing and did not consider herself a mountaineer. But Sally wasn't the one who needed to stop and turn around. "I am meant to be this tough, rugged mountaineer," David says, "and I celebrated my birthday by throwing up all over the place." Plagued by a throbbing headache and relentless nausea, David retreated to lower ground. He knew from previous climbs that he was prone to altitude sickness, but he thought circling the mountain at 3,000 … Continue reading →
