The initiation of endometriotic lesions is not well understood or characterized because endometriosis is typically diagnosed at an advanced stage. Endometriotic lesions are most often found on pelvic tissues and organs, especially the ovaries. To investigate the role of tissue tropism on ovarian endometrioma initiation, we adapted a well-characterized polyacrylamide microarray system to investigate the role of tissue-specific extracellular matrix and adhesion motifs on endometriotic cell attachment, morphology, and size. We report the influence of cell origin (endometriotic vs. non-endometriotic), substrate stiffness mimicking aging and fibrosis, and the role of multicellular (epithelial-stromal) cohorts on cell attachment patterns. We identify multiple ovarian-specific attachment motifs that significantly increase endometriotic (vs. non-endometriotic) cell cohort attachment that could be implicated in early disease etiology.

Introduction: During the healing process, the functional gradient attachment of the rotator cuff (RC) tendon-bone interface fails to regenerate, which severely impedes load transfer and stress dissipation, thereby increasing the risk of retears. As a result, the treatment of rotator cuff tears remains a significant clinical challenge.
Methods: In this study, a dual-crosslinked hyaluronic acid/polyethylene glycol (HA/PEG) hydrogel scaffold was synthesized using hyaluronic acid and polyethylene glycol as base materials.

Human induced pluripotent stem cells (hiPSCs) show great promise for personalized cell-based medicine, as they can be derived from easily accessible somatic cells and differentiated into all three germ layers without ethical concerns. This requires mass production of hiPSCs in 3D. However, contemporary methods for 3D culture result in hiPSC spheroids with significant size heterogeneity that is undesired for controlled differentiation and require the use of a high concentration of Rho-associated kinase inhibitor (RI) to improve the cell viability.

The development of high-performance neural interfaces is critical for advancing brain-machine communication and treating neurological disorders. A major challenge in neural electrode design is achieving a seamless biological-electronic interface with optimized electrochemical properties, mechanical stability, and biocompatibility. In this study, we introduce a hierarchical micronanostructured poly(3,4-ethylenedioxythiophene)-polydopamine (PEDOT-PDA) coating on titanium nitride (TiN) microelectrodes engineered to enhance electrophysiological signal recording and neural integration.

Wound healing has been extensively studied through the lens of inflammatory disorders and cancer, but limited attention has been given to hematophagy and arthropod-borne diseases. Hematophagous ectoparasites, including ticks, subvert the wound healing response to maintain prolonged attachment and facilitate blood-feeding. Here, we unveil a strategy by which extracellular vesicles (EVs) ensure blood-feeding and arthropod survival in three medically relevant tick species.

As a diverse natural polymer called Chitosan, it created ground-breaking advancements in nucleic acid therapeutic delivery techniques for handling essential DNA and RNA delivery hurdles. The article investigates how nucleic acids form stable polyplexes with chitosan through electrostatic bonds, as well as explores their chemical and biological properties. The review explores how molecular weight, combined with the degree of deacetylation, combined with advanced functionalization strategies, help enhance delivery results.
