Distinct Immunomodulatory Strategies Guide Mesenchymal Stromal/Stem Cell‐Mediated Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Bone regeneration by mesenchymal stem cells is strongly influenced by immune signals. This study shows that priming stem cells with regulatory immune cells or an inflammation‐resolving lipid molecule enhances bone formation through distinct immune pathways.

Electrical Stimulation Directs Formation of Perfused Vasculature in Engineered Tissues

open access: yesAdvanced Science, EarlyView.
Electrical stimulation (ESTIM) enhances vasculature formation in engineered human tissues. In 3D endothelial‐fibroblast constructs, conditioning with ESTIM promotes the formation of dense and highly branched networks that rapidly anastomose with mouse vasculature when implanted in vivo. Vessels formed under ESTIM are importantly functionally perfusable.

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

open access: yesAdvanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Land Use, Production Growth, and the Institutional Environment of Smallholders: Evidence from Burkinabe Cotton Farmers [PDF]

open access: yes
The cotton boom in Burkina Faso consisted of a growth in cotton land shares together with an overall increase in total cultivated land. This paper examines the impact of institutional changes in the cotton sector on the evolution of smallholders’ land ...
