Applied pressure enables efficient isolated mitochondrial transfer and stable mitochondrial DNA (mtDNA) transplantation into a range of mtDNA-depleted cell types to restore respiration.
Modulation of muscle stem cell redox state in culture both improves their amplification while maintaining a similar grafting potential as freshly isolated stem cells.
The H3K4 methyltransferase Setd1b is intrinsically required for hematopoietic stem and progenitor cell homeostasis and regulates lineage specification in mice.

Single cell RNA sequencing leads to identification and separation of transcriptionally and functionally heterogeneous, natural human satellite cells, including a subpopulation marked by CAV1 harboring quiescence phenotypes and engraftment potential.

About twenty temporal patterning genes are identified that drive an irreversible differentiation trajectory governing the heterogeneity and proliferative properties of cells in neural tumors with an early developmental origin.
Skeletal muscle organoids differentiated from human pluripotent stem cells offer a system for investigating myogenesis and satellite cell development with translational potential for muscular dystrophy modeling and therapy development.
Isotope tracing, mathematical modeling, and single-cell ATP analysis reveal changes in blood cell metabolism under various conditions, showing stressed hematopoietic stem cells support hematopoiesis through glycolytic ATP production via PFKFB3.

Repurposing of a drug designed for pain relief can quickly and reversibly slow biochemical and metabolic activities in cells and organs and could facilitate organ transplantation and prevent tissue injury.

Mutations causing proinsulin misfolding trigger unfolded protein response and lead to impaired proliferation and reduced mTORC1 signalling of developing beta-cells in a patient-derived induced pluripotent stem cell disease model.
