Occluders for the left atrial appendage that are patient-specific, thus ensuring better fitting and potentially less complications, can be made by 3D-printing inflatable polymer devices on the basis of data derived from computed tomography scans.
Grafting platelet-derived nanovesicles onto the surface of cardiosphere-derived cardiac stem cells enables the cells to better engraft in infarcted tissue following systemic injection in rats and pigs.
Commensal microbes engineered to convert natural compounds found in cruciferous vegetables into molecules with anticancer properties prevent carcinogenesis and cause the regression of colorectal cancer in mice fed with a vegetable diet.
A method inspired by cryptography maps neural activity to limb movement without requiring the simultaneous collection of neural activity in the motor cortex and of the corresponding physical actions.
A humanized mouse model of X-linked severe combined immunodeficiency suggests that the safety of correcting the human IL2RG gene in haematopoietic stem cells depends on both gene-correction frequency and the conditioning regimen used before cell transplantation.
This Perspective argues that tissue-manufacturing approaches relying on directed self-organization will enable the production of functional tissues with complex biological features.
Optical imaging of fluorescently labelled tissue illuminated by ultraviolet light does not require microscope slides and makes for a rapid alternative to conventional histology.
Prolonged local delivery, via an injectable hydrogel, of a miRNA known to induce cardiomyocyte proliferation stimulates the recovery of mice from myocardial infarction.
The expression of two DNA repair factors improves the recombination of single-stranded oligodeoxynucleotides with Cas9-induced double-strand breaks, facilitating precise and efficient gene editing.
The DNA mutation that causes Duchenne muscular dystrophy in mice can be corrected, with minimal off-target effects, by gold nanoparticles carrying the CRISPR components.
A theoretical model of chromatin packing heterogeneity predicts patterns in gene expression and can be used to screen for effective chemotherapeutic adjuvants.
This Review discusses the role of glia as an effector of the performance and integration of devices implanted in the brain, and the implications of this for device development.
Flexible piezoelectric sensors can detect mechanical deformations in the gastrointestinal tract of ambulating pigs and simultaneously harvest energy from it.
High-throughput screening of large libraries of cyclic peptides expressed in bacteria yields rescuers of the pathogenic misfolding of proteins associated with neurodegenerative diseases.
This Perspective discusses recent technological developments in flow cytometry and DNA sequencing that enable the interrogation of T-cell specificities in infection, cancer and autoimmunity to inform disease development and treatment.
