    Human iPS Cell Derived RPE Strips for Secure Delivery of Graft Cells at a Target Place with Minimal Surgical Invasion

    The authors produced a quickly formed human iPSC-retinal pigment epithelium (RPE) strip in as short as 2 days, which showed a potency to partly expand with the correct apical/basal polarity in vivo, although limited in expansion area in the presence of healthy host RPE.

    Abstract

    A Fluid-Powered Refillable Origami Heart Pouch for Minimally Invasive Delivery of Cell Therapies in Rats and Pigs

    Investigators developed a fluid-driven heart pouch with a memory-shaped microfabricated lattice structure inspired by origami. The pore size of the membrane was around 0.4 μm, which allowed for the penetration of growth factors and exosomes.
