Body: A team of researchers recently proved the ability to grow human-derived blood vessels in a pig -- a novel approach that has the potential for providing unlimited human vessels for transplant purposes.
Body: A study of the second HIV patient to undergo successful stem cell transplantation from donors with a HIV-resistant gene, finds that there was no active viral infection in the patient's blood 30 months after they stopped anti-retroviral therapy, according to a case report.
Body: Scientists have sent adult human stem cells to the International Space Station (ISS). Researchers will explore the production of human tissue in weightlessness.
Body: Scientists say they have successfully turned back the biological hands of time, coaxing adult human cells in the laboratory to revert to a primitive state, and unlocking their potential to replace and repair damage to blood vessels in the retina caused by diabetes. The findings from this experimental study, they say, advance regenerative medicine techniques aimed at reversing the course of diabetic retinopathy and other blinding eye diseases.
Body: A population of stem cells with the ability to generate new bone has been newly discovered by a group of researchers.
Body: Researchers have analyzed all cell types in the human ovary and found that the hotly debated so-called egg stem cells do not exist.
Body: A new study shows that lung stem cell secretions -- specifically exosomes and secretomes -- delivered via nebulizer, can help repair lung injuries due to multiple types of pulmonary fibrosis in mice and rats.
Body: Parkinson's disease researchers have used gene-editing tools to introduce the disorder's most common genetic mutation into marmoset monkey stem cells and to successfully tamp down cellular chemistry that often goes awry in Parkinson's patients.
Body: Our skin protects us from physical injury, radiation and microbes, and at the same time produces hair and facilitates perspiration. Details of how skin cells manage such disparate tasks have so far remained elusive. Now, researchers have systematically mapped skin cells and their genetic programs, creating a detailed molecular atlas of the skin in its complexity.
Body: In the event of a bone fracture, fatty acids in our blood signal to stem cells that they have to develop into bone-forming cells. If there are no blood vessels nearby, the stem cells end up forming cartilage. The finding that specific nutrients directly influence the development of stem cells opens new avenues for stem cell research.
