This study aimed to investigate the impact of fibroblasts (MRC-5) on the extracellular matrix (ECM) microenvironment of endothelial cells (ECs) during the vascularization of skin-derived ECM hydrogel in vitro. Two types of ECs were studied: human dermal microvascular endothelial cells (HMEC) and human pulmonary microvascular endothelial cells (HPMEC). Results showed that the presence of MRC-5 fibroblasts increased the stiffness of the hydrogel and led to larger fiber diameters and increased porosity. Extensive collagen fiber remodeling occurred in the ECM hydrogel with MRC-5 fibroblasts. Additionally, higher levels of fibulin-1 and fibronectin were deposited in the hydrogel when co-cultured with MRC-5 fibroblasts. These findings suggest that MRC-5 fibroblasts play a role in modifying the ECM microenvironment, promoting vascularization through dynamic ECM remodeling.

Introduction: Copper complexes, as endogenous metals, have potential in cancer therapy, addressing issues associated with cisplatin. Since cisplatin uses Copper Transporter 1 (CTR1) for cellular entry, copper complexes may utilize this pathway to enhance transport efficiency.
Methods: The Cu/Na dipicolinic acid complex was synthesized to assess its cytotoxicity, induction of apoptosis, drug resistance, and inflammation in cancerous and normal lung cells.

Mechanical strain plays a significant role in lung pathophysiology. Current two-dimensional (2D) models fail to capture the lung's dynamic mechanical environment. We developed mechanically strained 2D and more complex three-dimensional (3D) alveolar epithelial-fibroblast co-cultures and organoids using the Flexcell cell stretching bioreactor.

: Adult-type diffuse gliomas, including astrocytoma and glioblastoma multiforme (GBM), are brain tumors with a very poor prognosis. While current treatment options for glioma patients are not providing satisfactory outcomes, research indicates that natural compounds could serve as alternative treatments. However, their low bioavailability requires nanotechnology solutions, such as liposomes.

A series of acridine derivatives, namely 10-(4-substituted benzyl)-9-(4-hydroxyphenyl)-3,3,6,6-tetramethyl-3,4,6,7,9,10-tetrahydroacridine-1,8(2H,5H)-diones, was synthesized via the Hantzsch-type multicomponent reaction between dimedone, 4-hydroxybenzaldehyde and 4-substituted benzylamine. The cytotoxic potential of these compounds was evaluated against human ovarian (A2780), melanoma (A375), colon (HCT 116) and breast cancer (MCF-7) cell lines, as well as normal human lung fibroblasts (MRC-5) and keratinocytes (HaCaT). Tested cell lines displayed different but moderate sensitivity to the investigated compounds, with the exception of compounds with a methyl (2) and a bromo group on the benzyl ring (6).

Polyhexamethylene guanidine (PHMG), a major component of humidifier disinfectants (HDs) linked to fatal lung injuries, has been implicated in the development of pulmonary fibrosis. However, most previous studies have primarily focused on epithelial injury, with limited attention to fibroblast activation - a central mechanism in fibrogenesis. In this study, we present an integrated testing strategy (ITS) designed for the early in vitro screening of fibrogenic agents, centered on fibroblast-to-myofibroblast transition (FMT) as a core functional and mechanistic endpoint.
