Human pluripotent stem cells (hPSC) can be directed to differentiate in vitro into insulin-prorducing beta cells (SC-β). Although these cells accurately respond to glucose and can reverse diabetes in preclinical models improvments in the final cell products are desirable. For example, safety, controlling the cellular compositions and protection against immune rejection may be addressed by genetic modifications of SC-β pre-transplantation. To screen for gene targets, we have generated a human embryonic stem cell line (hESC) that constitutively express the enhanced specificity Streptococcus pyogenes Cas9 (eSpCas9) gene, knocked-in into the GAPDH locus.

Liver tissue engineering offers potential in liver transplantation, while the development of hydrogels for scalable scaffolds incorporating natural components and effective functionalities is ongoing. Here, we propose a novel microfluidic 3D printing hydrogel derived from decellularized fish liver extracellular matrix for liver regeneration. By decellularizing fish liver and combining it with gelatin methacryloyl, the hydrogel scaffold retains essential endogenous growth factors such as collagen and glycosaminoglycans.

Facial nerve injuries lead to significant functional impairments and psychological distress for affected patients. Effective repair of these injuries remains a challenge. For longer nerve gaps, the regeneration outcomes after nerve grafting remain suboptimal due to limited sources and postoperative immune responses.

The discovery of leucine-rich-containing G-protein-coupled receptor 5 (Lgr5) as an intestinal adult stem cell marker had blazed a trail in stem cell biology and laid the foundations of modern organoid technology. Up to date, several well-established intestinal organoid protocols have been reported in the literature from different sources, including adult and induced pluripotent stem cells. Here, we demonstrate a BALB/c mouse-derived intestinal organoid culture protocol, passaging, and cryopreservation procedures.

Astroglia are integral to brain development and the emergence of neurodevelopmental disorders. However, studying the pathophysiology of human astroglia using brain organoid models has been hindered by inefficient astrogliogenesis. In this study, we introduce a robust method for generating astroglia-enriched organoids through BMP4 treatment during the neural differentiation phase of organoid development.

Inhibin, β, which is also known as INHBA, encodes a protein that belongs to the Transforming Growth factor-β (TGF-β) superfamily, which plays a pivotal role in cancer. Gastrointestinal tract (GI tract) cancer refers to the cancers that develop in the colon, liver, esophagus, stomach, rectum, pancreas, and bile ducts of the digestive system. The role of INHBA in all GI tract cancers remains understudied.
