Scientists have converted skin cells from healthy adults directly into motor neurons without going through a stem cell state. The technique makes it possible to study motor neurons of the human central nervous system in the lab. Unlike commonly studied mouse motor neurons, human motor neurons growing in the lab would be a new tool since researchers can’t take samples of these neurons from living people but can easily take skin samples.
While Zika virus causes devastating damage to the brains of developing fetuses, it one day may be an effective treatment for glioblastoma, a deadly form of brain cancer. New research shows that the virus kills brain cancer stem cells, the kind of cancer cells most resistant to standard treatments.
ViraCyte LLC, a clinical stage biopharmaceutical company developing cellular immunotherapies for severe infections, reported positive data from a Phase 2 clinical trial evaluating its T-cell immunotherapy product, Viralym-M. The results were reported by ViraCyte lead investigators at Baylor College of Medicine in the Journal of Clinical Oncology.
A new review looks at the potential of fetal membranes, which make up the amniotic sac surrounding the fetus during pregnancy, for regenerative medicine.
The first subject has been transplanted in an investigator-initiated study of Cordin™ for patients with severe aplastic anemia (AA) or hypoplastic myelodysplastic syndrome (MDS) who have no available matched donor.
A new study in mice published in The Journal of Neuroscience details a potential therapeutic strategy that uses stem cells to promote recovery of motor activity after spinal cord injury.
Scientists at the University of Oxford have developed a new method to 3D-print laboratory-grown cells to form living structures. The approach could revolutionize regenerative medicine, enabling the production of complex tissues and cartilage that would potentially support, repair or augment diseased and damaged areas of the body.
Scientists have created healthy offspring from genetically infertile male mice, offering a potential new approach to tackling a common genetic cause of human infertility.
How do the multiple different cell types in the blood develop? Scientists have been pursuing this question for a long time. According to the classical model, different developmental lines branch out like in a tree. The tree trunk is composed of stem cells and the branches are made up of various types of progenitor cells that can give rise to a number of distinct cell types. Then it further branches off into the specialized blood cells, i.e., red blood cells, blood platelets and various types of white blood cells that are part of the immune system. In recent years, however, doubts about this model have arisen.
UCLA researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research, led by scientists Heather Christofk and William Lowry, may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss associated with such factors as hormonal imbalance, stress, aging or chemotherapy treatment.
