Special Issue Information
Dear Colleagues,
A hallmark of chronic kidney disease is renal fibrosis, which is characterized by excessive production and deposition of extracellular matrix leading to disruption of renal parenchyma and progressive loss of kidney function to end-stage kidney disease. Fibrogenesis of the kidney is a complex process resulting from tubular epithelial cell damage, infiltration and activation of bone marrow-derived cells such as macrophages, T cells, and fibroblast precursors, and activation of interstitial fibroblasts. Activated fibroblasts/myofibroblasts produce excessive amounts of extracellular matrix, which impairs normal kidney structure and causes progressive loss of kidney function. Currently, there is no effective treatment for renal fibrosis. Therefore, there is an urgent need to understand the molecular and cellular mechanisms underlying the pathogenesis of renal fibrosis and develop novel therapeutic strategies. Matrix-producing fibroblasts/myofibroblasts are the major sources of extracellular matrix. Recent studies indicate that these cells may derive from multiple sources including resident fibroblasts, tubular epithelial cells/endothelial cells, and bone marrow precursors/fibrocytes. A number of chemokines, cytokines, and signaling pathways have been reported to play a role in the development of renal fibrosis including MCP-1, CXCL16, transforming growth factor-β (TGF-β)/Smad, platelet-derived growth factors (PDGF), adiponectin, IL-4, IL-13, JAK/STAT, AMP-activated protein kinase (AMPK), Wnt/β-catenin, notch signaling, hedgehog signaling, integrins, renin-angiotensin-aldosterone system, and endothelin. Recently, omics-based approaches have provided additional insights into the molecular mechanisms and therapeutic targets of renal fibrosis.
In this research topic, we welcome submission of original research articles, perspectives, and reviews on current understanding of the cellular and molecular mechanisms of renal fibrosis as well as development of novel therapeutic strategies for renal fibrosis.

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.
