Background: Hypertrophic scar (HS) is a severe skin fibrosis. Transplanting stem cells carrying anti-fibrotic cytokine genes, like interferon-gamma (IFN-γ), is a novel therapeutic strategy. Human amniotic epithelial cells (hAECs) are ideal seed cells and gene vectors.

Diseases and injuries can cause significant bone loss, leading to increased medical expenses, decreased work efficiency, and a decline in quality of life. Bone tissue engineering (BTE) is gaining attention as an alternative to autologous and allogeneic transplantation due to the limited availability of donors. Biomaterials represent a promising strategy for bone regeneration, and their design should consider the three key processes in bone tissue engineering: osteogenesis, bone conduction, and bone induction.

Biotics are increasingly being used in the treatment of irritable bowel syndrome (IBS). This study aimed to assess the efficacy and safety of a mixture of microencapsulated sodium butyrate, probiotics ( DSM 26357, DSM 32418, DSM 32946, DSM 32403, and DSM 32269), and short-chain fructooligosaccharides (scFOSs) in IBS patients. This was a randomized, double-blind, placebo-controlled trial involving 120 adult participants with IBS.

Background/objectives: This study focuses on the development and evaluation of novel alginate-poly[2-(methacryloyloxy)ethyl]trimethylammonium chloride (PMETAC) microcapsules for encapsulating pancreatic islets to address insulin deficiency in diabetes.
Methods: In previous research, we fabricated and characterized PMETAC microcapsules, evaluating their stability and permeability in vitro. This study further probes the capsules in vivo, focusing on the functional activity of the encapsulated islets post-transplantation, their viability extension, and the assessment of the immunoprotective, antifibrotic properties, and biostability of the capsules.
Single-layer graphene oxide nanosheets induce proliferation and Osteogenesis of single-cell hBMSCs encapsulated in Alginate Microgels.

Microfluidics cell encapsulation offers a way to mimic a 3D microenvironment that supports cell growth and proliferation, while also protecting cells from environmental stress. This technique has found extensive applications in tissue engineering and cell therapies. Several studies have demonstrated the advantages of graphene oxide (GO) as an osteogenic inducer; however, the significance of GO on stem cell fate in the single-cell state is still unclear.
