Special Issue Information

Dear Colleagues,

The microenvironment within tissues is a dynamic determinant of cell behaviour and tissue function, influencing tissue development, organisation, homeostasis, and disease progression. Understanding the microenvironment is therefore important to recreating complex tissue systems in the laboratory and elucidating the mechanisms that govern tissue repair, pathology, and treatment response for new therapeutic opportunities.

This Special Issue, titled “Modelling Tissue Microenvironments in Development and Disease”, aims to showcase advancements in the field. We invite contributions that employ a range of innovative approaches, including three-dimensional (3D) cell culture systems such as self-organising organoids, spheroids, and bioprinted tissues, as well as in silico models.

Key areas of interest include the following:

  • The development of novel cell cultures and in silico models that closely mimic healthy and pathological tissue conditions.
  • Studies of the roles of different components of the tissue microenvironment, such as the extracellular matrix (ECM), signalling molecules, and physical properties (e.g., mechanical cues), in tissue development and disease progression.
  • Application of understanding the tissue microenvironment for drug discovery, toxicology, and regenerative medicine.

By compiling a comprehensive collection of original research articles, reviews, and communications, this Special Issue will serve as a valuable resource for both fundamental/basic and applied research in developmental biology, pathology, tissue engineering, regenerative medicine, and related disciplines.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The periodontal ligament (PDL) is crucial for maintaining the integrity and functionality of tooth-supporting structures. Mechanical forces applied to the tooth during orthodontic tooth movement generate pore pressure gradients, leading to interstitial fluid movement within the PDL. The generated fluid shear stress (FSS) stimulates the remodeling of PDL and alveolar bone. Herein, we present the construction of a parallel fluid-flow apparatus to determine the effect of FSS on PDL cells. The chamber was designed and optimized using computer-aided and computational fluid dynamics software. The chamber was formed by PDMS using a negative molding technique. hPDLCs from two donors were seeded on microscopic slides and exposed to FSS of 6 dyn/cm2 for 1 h. The effect of FSS on gene and protein expression was determined using RT-qPCR and Western blot. FSS upregulated genes responsible for mechanosensing (FOS), tissue formation (RUNX2, VEGFA), and inflammation (PTGS2/COX2, CXCL8/IL8, IL6) in both donors, with donor 2 showing higher gene upregulation. Protein expression of PTGS2/COX2 was higher in donor 2 but not in donor 1. RUNX2 protein was not expressed in either donor after FSS. In summary, FSS is crucial in regulating gene expression linked to PDL remodeling and inflammation, with donor variability potentially affecting outcomes. Full article
