Elucidating cellular origins and TME dynamic evolution in NSCLC through multi-omics technologies.

Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality. Despite progress in targeted therapies and immunotherapy, resistance driven by tumor heterogeneity and dynamic tumor microenvironment (TME) remodeling persists. Multi-omics (single-cell/spatial transcriptomics) reveals lung adenocarcinoma (LUAD) origins in alveolar type 2 (AT2) cells and lineage plasticity via SOX2/WNT/YAP pathways driving aggressive subtypes.

Fabrication and characterization of a pro-angiogenic hydrogel derived from the human placenta.

Various hydrogels derived from the xenogeneic extracellular matrix (ECM) have been utilised to promote the repair and reconstruction of numerous tissues; however, there are few studies on hydrogels derived from allogeneic specimens. Human placenta derived hydrogels have been used in the therapy of ischaemic myocardium; however, their physicochemical properties and effects on cellular behaviour remain elusive. As the human placenta retains pro-angiogenic growth factors, it is hypothesized that the placenta hydrogels possess the potential to improve angiogenesis.

Production and Characterization of Composite Chitosan Hydrogel Containing Extracellular Matrix Particles for Tissue Engineering Applications.

Chitosan-based hydrogels have been extensively used for tissue regeneration due to the excellent biocompatibility and biodegradability. For lack of endogenous extracellular biomacromolecules, its application is obviously limited. Because of robust biological activity, porcine small intestinal submucosa (SIS) has been considered as promising candidates to increase the bioactivity of hydrogels.

Preparation and characterization of pro-angiogenic gel derived from small intestinal submucosa.

Unlabelled: Gels derived from decellularized small intestinal submucosa (SIS) have been used to repair ischemic myocardium and deliver protein drug. However, their material properties and effects on cell behavior are not well understood, in part because of the difficulty of gelling in vitro. In this study, soluble SIS matrix, which was easily handled and could effectively gel, was successfully prepared using a modified method.
