“…We isolated pBTSCs from porcine biliary trees and generated organoids by protocols established previously for human endodermal stem/progenitors 54 . The cells were maintained in serum-free Kubota’s Medium supplemented with 0.1% hyaluronans, conditions proven successful for ex vivo maintenance of organoids for weeks with the maintenance of stem/progenitor traits in hBTSCs, hHpSCs, and hHBs 54 , 55 . In Supplementary Fig.…”

“…One interesting aspect of this study worth further developing is the use of the polyurethane scaffold loaded with iLPC organoids, which can serve as a "liver patch" that can be applied on the liver surface. Several other studies have reported liver cell/organoid patches [39,40,41,42,43], and the advantage of such methods is the ability to easily apply this using minimally invasive methods such as laparoscopic surgery, and this can be delivered on multiple areas of the liver surface, and even repeated over time. Most of these studies have used extra-cellular matrix and synthetic hydrogels [39,40], stacked cell sheets [43] or electro-spun fibres [42] to create the patches, however these methods create thin delicate patches that can be difficult to physically manipulate without damaging them.…”

“…After that, the Y-miR122-induced hepatocyte-like cells (YR-heps) and HUVECs were cocapsulated in microgels via droplet microfluidic technology, which enhanced both hepatic functions and the vascularization (Scheme B). Patches-assistant transplantation of big grafts on solid organs has shown great potential. With the assistance of biocompatible and adhesive hyaluronic acid-dopamine (HA-DA) patches, we transplanted the multiple cell-laden microgel grafts in ALF mice. Results showed that the implanted patches could transfer cell-laden microgels effectively to the damaged liver area.…”
