Using a lineage tracing model, it is demonstrated that adult murine hematopoiesis is contingent on the continuous output from HSCs, with quantitative contributions that are dependent on lineage-type and age.
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.
A new platform for imaging live Drosophila adults yields vivid movies of the midgut over prolonged time scales, opening the door to the real-time study of organ renewal dynamics in a near-native context.
The identification of key determinants of LSC “stemness” and LSC differentiation that is reversible through an epigenetic mechanism may have considerable implications in understanding leukemia and designing effective therapies.
The requirement for WNT signaling in mesendoderm differentiation is temporally separate from that of ACTIVIN signaling and acts to switch the output of ACTIVIN/SMAD2 from pluripotency maintenance to mesendoderm patterning.
Heterogeneous epidermal stem cells define a niche for tactile sensation via providing a unique ECM and tissue architecture for nerves, revealing their new functions in coordinated sensory organ formation.
A bioengineering approach identifies tissue morphology as an effective variable for controlling the inception of neural organoid morphogenesis via induction of a biomimetic, singular neural rosette tissue cytoarchitecture.
Sequential live imaging of abnormal skull bone fusion in zebrafish reveals a deeply conserved role of two transcription factors, Twist1 and Tcf12, in regulating stem cell activity during growth of the skull.
Modulation of muscle stem cell redox state in culture both improves their amplification while maintaining a similar grafting potential as freshly isolated stem cells.
