UrduUT Southwestern stem cell scientists find that stringent lineage tracing is crucial for studies of nerve cell regeneration. Their results, which are published in Cell, show that this tracing is far from routine in the field and suggest that earlier studies reporting “striking” regeneration results must be reexamined.

Potential Target for Treating Many Cancers Found Within GLI1 Gene
Scientists from the Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago found that a region within the DNA of the cancer-promoting GLI1 gene is directly responsible for regulating this gene’s expression. These findings, published in the journal Stem Cells, imply that this region within GLI1 could potentially be targeted as cancer treatment, since turning off GLI1 would interrupt excessive cell division characteristic of cancer.

Stem Cell Treatments ‘Go Deep’ to Regenerate Sun-Damaged Skin
For a while now, some plastic surgeons have been using stem cells to treat aging, sun-damaged skin.

Image Analysis Technique Provides Better Understanding of Heart Cell Defects
Many patients with heart disease face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, which may be used in advanced drug screens and cell-based therapies. However, current image analysis techniques don’t allow researchers to analyze heterogeneous, multidirectional, striated myofibrils typical of immature cells. In the Journal of Applied Physics, researchers showcase an algorithm that combines gradient methods with fast Fourier transforms to quantify myofibril structures in heart cells with considerable accuracy.
