Microneedle‐Based Biofertilizer Delivery Improves Plant Growth Through Microbiome Engineering

open access: yesAdvanced Functional Materials, EarlyView.
This figure shows how microneedles are used to deliver biofertilizers to enhance plant growth through microbial migration, metabolic reprogramming, and changes in plant endogenous microbiome. Abstract This study presents a microneedle‐based system for the delivery of rhizospheric biofertilizers into plant tissues to enhance growth.

Revisiting the distribution and total amount of nitrogen fixation across the Kuroshio

open access: yesLimnology and Oceanography Letters
The Kuroshio Current, a western boundary current in the North Pacific Ocean, is regarded as a hotspot of nitrogen fixation that drives marine primary productivity and biogeochemical cycles.

Lucerne (Medicago sativa) or grass-clover as cut-and-carry fertilizers in organic agriculture [PDF]

open access: yes, 2013
On-farm nitrogen fixation is a driving force in organic agriculture. The efficiency with which this nitrogen is used can be increased by using lucerne (Medicago sativa) or grass-clover directly as sources of fertilizer on arable land: cut-and-carry ...

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

3D Differentiation of Bone‐Marrow Derived Mesenchymal Stromal Cells into the Keratocyte Lineage for Corneal Bioprinting

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a novel differentiation protocol for generating corneal stromal keratocyte‐like cells using drop‐on‐demand bioprinting and a collagen‐based hydrogel. The bioprinted constructs maintained a stable dome shape over 21 days while exhibiting upregulated CSK markers postdifferentiation.
