Multiplexed immunofluorescent (IF) techniques enable the detection of multiple antigens within the same sample and are therefore useful in situations where samples are rare or small in size. Similar to standard IF, multiplexed IF yields information on both the location and relative amount of detected antigens. While this method has been used primarily to detail cell phenotypes, we have recently adapted it to profile the extracellular matrix (ECM), which provides technical challenges due to autofluorescence and spatial overlap. This chapter details the planning, execution, optimization, and troubleshooting to use multiplexed IF to profile the ECM of human fallopian tube tissue.

Background: Superficial injection of hyaluronic acid (HA)-based gels is a widely used method to restore skin quality and achieve a more youthful appearance. While the clinical benefits of such procedures are well established, their biological mechanisms of action remain poorly understood.
Objective: This study aimed to evaluate the effectiveness of two cross-linked HA gels (IPN-12.

Biofilms-microbial communities encased in a self-produced extracellular matrix-pose a significant challenge in clinical settings due to their association with chronic infections and antibiotic resistance. Their formation in the human body is governed by a complex interplay of biological and environmental factors, including the biochemical composition of bodily fluids, fluid dynamics, and cell-cell and cell-surface interactions. Improving therapeutic strategies requires a deeper understanding of how host-specific conditions shape biofilm development.

Background And Aims: Cholangiopathies, including primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC), and post-COVID-19 cholangiopathy (PCC), involve chronic cholangiocyte injury, senescence, epithelial-stromal crosstalk, and progressive fibrosis. However, effective in vitro models to capture these interactions are limited. Here, we present a scaffold-free 3D multilineage spheroid model, composed of hepatocyte-like cells (HepG2), cholangiocytes (H69), and hepatic stellate cells (LX-2), designed to recapitulate early fibrogenic responses driven by senescent cholangiocytes.

Uterine fibroids are the most common gynecological tumors, characterized by excessive production of extracellular matrix. Despite their prevalence, the cellular mechanisms governing fibroid growth remain poorly understood. Current in vitro models for fibroids do not replicate the complex 3D tissue mechanics, structure, and extracellular matrix components of fibroids, which may limit our understanding of fibroid pathogenesis.

Objective: Porphyrins are ubiquitous metabolites and are constitutive of the bacterial metabolome of healthy skin. Their consideration has until now been limited to their pro-inflammatory activity in acne vulgaris. The present work suggests a new role for these molecules in the onset of skin ageing.
