Naive hPSCs can readily give rise to human trophoblast stem cells, thus demonstrating their extraembryonic lineage potential and providing a new model system to study human trophectoderm specification.
Bulk and single-cell RNA-seq data demonstrated that muscle stem cells express low levels of canonical endothelial cell markers, including VEGFA receptors, and VEGFA-FLT1 pathway has a drastic effect on muscle stem cell survival through AKT1 in vitro and in vivo.
In vivo modulation of the prostaglandin, interferon, or granulocyte colony-stimulating factor pathway induces rapid and specific transcriptional changes in hematopoietic stem cells with significant heterogeneity in the cellular response.
Adult stem cells sense nearby tissue damage and recruit immune cells to help them direct efforts towards containing a breach in the epithelial barrier.
A conserved alternative splicing program is specific to planarian stem cells and is controlled by the highly conserved splicing factors CELF and MBNL; therefore, this mode of regulating stem cells is likely ancestral to all animals.
A femur transplantation model of bone marrow regeneration highlights the plasticity of periosteal skeletal stem cells and their ability to contribute to bone marrow niche regeneration, ultimately facilitating hematopoietic regeneration.

Parenchymal astrocytes are quiescent neural stem cells whose neurogenic potential can be unleashed by targeted manipulations guided by single-cell RNA sequencing data.

Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.
