Extracellular vesicles (EVs) constitute one of the main mechanisms by which cells communicate with the surrounding tissue or at distance. Vesicle secretion is featured by most cell types, and adult mesenchymal stromal cells (MSCs) of different tissue origins have shown the ability to produce them. In recent years, several reports disclosed the molecular composition and suggested clinical indications for EVs derived from adult MSCs. The parental cells were already known for their roles in different disease settings in regulating inflammation, immune modulation, or transdifferentiation to promote cell repopulation. Interestingly, most reports also suggested that part of the properties of parental cells were maintained by isolated EV populations. This review analyzes the recent development in the field of cell-free therapies, focusing on several adult tissues as a source of MSC-derived EVs and the available clinical data from in vivo models.

The walls of all embryonic, foetal, and adult blood vessels contain mesodermal progenitors, distributed as pericytes in capillaries and micro vessels, and fibroblastic cells in the tunica adventitia of larger veins and arteries. Following dissociation, selection by flow cytometry, and culture, those perivascular cells turn into bona fide mesenchymal stem cells of which they possess all attributes. In vivo, the adventitial cellular niche supports several spatially-organized subsets of mesodermal progenitors biased toward either osteo-, adipo-, or fibrogenesis, and dominated by more primitive, multi-lineage stem-like cells.

Xenopus embryo serves as an ideal model for teratogenesis assays to observe the effects of any compounds on the cellular processes crucial for early development and adult tissue homeostasis. In our screening of a chemical library with frog embryo, caffeic acid phenethyl ester (CAPE) was found to upregulate the FGF/MAPK pathway, disrupting germ layer formation in early development. Exposure to CAPE interfered with the formation of anterior-posterior body axis and of ectodermal derivatives such as eyes, dorsal fin and pigment cells.

Aberrant extracellular matrix (ECM) production by dermal fibroblasts drives fibrotic skin diseases, which has an adverse impact on the lives of patients. Current treatments are limited; therefore, the development of new antifibrotic strategies is necessary. The aim of the present study was to investigate zinc finger 469 (ZNF469) as a potential ECM regulator in skin fibrosis.

Leiomyomas are the most common benign mesenchymal tumors of the esophagus, and they account for nearly two-thirds of benign esophageal neoplasms. The leiomyomas of the esophagus present with numerous nonspecific symptoms and signs, including dysphagia, shortness of breath, anorexia, weight loss, chronic cough, and bowel obstruction. The patient in this case report presented with moderate to severe right upper quadrant pain and mild dysphagia, which initially prompted evaluation for hepatobiliary pathology.

Introduction: Epithelioid sarcoma (ES) is an uncommon malignant mesenchymal tumour that occurs in young adults and adolescents. Few documented series have elucidated the cytopathological features and immunostaining results of epithelioid sarcoma. Here, we present one of the largest series documenting 15 cases of ES.
