This issue includes a Focus on cell therapies, with an emphasis on cardiac regenerative medicine and immunotherapy. Also highlighted in this issue are a replenishable epicardial device for the sustained delivery of therapeutics, the mechanical in vivo maturation of human intestinal organoids, a cell-culture method for the formation of organ-specific metastases, and a microvasculature-on-a-chip device.
The cover illustrates the delivery of a cell therapeutic to diseased tissue.

For cell therapies to transition from promises to products, increased efforts need to be put into the identification of the factors and biological mechanisms that affect safety and efficacy, and into the design of cost-effective methods for the harvesting, expansion, manipulation and purification of the cells.
A physiologically relevant microvasculature-on-a-chip device enables the study of microvascular pathology associated with inflammation and haematological diseases.
Heart tissue with an adult-like phenotype can be obtained by electromechanically conditioning, with increasing intensity, early-stage human induced pluripotent stem cells derived from cardiomyocytes.
This Perspective provides an overview of recent cardiac cell therapies and their limitations, and argues for the need of deeper mechanistic understanding that informs the use of cells and of next-generation cell-free biologics in cardiac regeneration.
This Review discusses the manufacturing of cell products for clinically advanced cell therapies, and highlights potential manufacturing bottlenecks and solutions towards the cost-effective commercialization of the therapies.
This Review Article provides an overview of chimeric antigen receptors (CARs) for T cells and discusses engineering strategies for the design of next-generation CAR-T therapies for haematologic and solid cancers.
An epicardial device that enables sustained and repeated administration of small molecules, macromolecules and cells directly to the epicardium provides therapeutic benefits in a rat model of myocardial infarction.
Uniaxial strain provided by compressed nitinol springs incorporated in human intestinal organoids transplanted into the mouse mesentery enhances organoid growth and maturation, and improves the similarity of the organoids to native human intestine.
A cell-culture method involving decellularized tissue scaffolds enables the spontaneous formation of cell colonies that phenotypically recapitulate in vivo organ-specific cancer metastases.
An endothelialized microfluidic system that recapitulates physiological properties of the microvasculature enables the real-time visualization of vascular-pathology features associated with sickle-cell disease and malaria, with high spatiotemporal resolution.
For cell therapies to transition from promises to products, increased efforts need to be put into the identification of the factors that affect safety and efficacy, and into cell manufacturing.
