The Stem Cell Science Round Up

Variable Outcomes in Neural Differentiation – Investigators have found that the variability in outcomes during in vitro differentiation of human PSCs to neural lineage cells is due to differences in a developmental signaling pathway.

Human Embryo-Like Model Created from Human Stem Cells – A new model has been developed to study gastrulation in early development using human ESC-derived gastruloids.

Boosting Natural Killer Cell Activity with iPSCs – Using iPSCs and deleting a key gene, scientists have created natural killer cells with an enhanced ability to inhibit leukemic cells, both in vivo and in vitro.

Brain Organoids that Predict Drug Permeability – Researchers have generated human central nervous system organoids with a barrier that is selective to small molecules, and that secrete cerebrospinal fluid.
