Special Issue Information

Dear Colleagues,

New blood vessels are formed during embryonic development and post-natal life for physiological repair processes such as wound healing, exercise, and placenta growth. The balance between pro- and anti-angiogenic cues is essential for forming normal functional microvasculature composed of mature vessels with a hierarchical structure of arterioles, capillaries, and venules. The interaction between growing blood vessels and surrounding molecular and cellular microenvironments is a determining factor for the extent of vascular network morphogenesis. During embryonic development, the growth of the vasculature network is influenced by the extent of tissue morphogenesis, but also, it can be the trigger of tissue formation or growth and differentiation processes by producing signals in a paracrine manner. New blood vessels can also be critical to coordinating tissue repair or regeneration and preventing the deregulated, disease-promoting process. Abnormal morphogenesis of new blood vessels involves various pathophysiological processes such as cancer, ischemic vascular diseases, diabetes and Alzheimer’s disease. A better understanding of the molecular basis for vascular network morphogenesis will impact the development of new therapeutic strategies to target the microvasculature and angiogenesis in such diseases.

This Special Issue welcomes original research articles and review papers on all molecular and cellular aspects of vascular formation and its interrelation with tissue formation/repair.

Potential topics include, but are not limited to, the following:

  • Autocrine and paracrine signaling in vascular development
  • Molecular mechanisms of vascular lumen formation
  • Cell signaling paracrine in post-natal angiogenesis
  • Tumor microenvironment and angiogenesis
  • Ischemia-induced angiogenesis
  • Vascular malformations of the brain
  • Neurovascular diseases
  • Molecular mechanisms of angiogenesis in exercise

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Vascular anomalies (VAs) are morphogenesis defects of the vascular system (arteries, capillaries, veins, lymphatic vessels) singularly or in complex combinations, sometimes with a severe impact on the quality of life. The progress made in recent years with the identification of the key molecular pathways (PI3K/AKT/mTOR and RAS/BRAF/MAPK/ERK) and the gene mutations that lead to the appearance of VAs has allowed the deciphering of their complex genetic architecture. Understanding these mechanisms is critical both for the correct definition of the phenotype and classification of VAs, as well as for the initiation of an optimal therapy and the development of new targeted therapies. The purpose of this review is to present in synthesis the current data related to the genetic factors involved in the etiology of VAs, as well as the possible directions for future research. We analyzed the data from the literature related to VAs, using databases (Google Scholar, PubMed, MEDLINE, OMIM, MedGen, Orphanet) and ClinicalTrials.gov. The obtained results revealed that the phenotypic variability of VAs is correlated with genetic heterogeneity. The identification of new genetic factors and the molecular mechanisms in which they intervene, will allow the development of modern therapies that act targeted as a personalized therapy. We emphasize the importance of the geneticist in the diagnosis and treatment of VAs, as part of a multidisciplinary team involved in the management of VAs. Full article
