Special Issue Information

Dear Colleagues,

Over the years, stem cell therapy has garnered significant interest as a treatment for various diseases. The therapeutic potential of mesenchymal stem cells (MSCs) has been explored in numerous animal models and veterinary patients. While preclinical research has reported beneficial treatment effects, these findings have led to the initiation of several clinical trials, which have yielded inconsistent results. Additionally, recent experiences have highlighted numerous reports of adverse events and side-effects associated with MSC therapy.

This experience underscores that there are many challenges and pitfalls in regenerative medicine that are often overlooked in the literature, hindering progress in the field and leading to unnecessary financial costs and safety concerns. A comprehensive understanding of these limitations, challenges, and pitfalls is essential for fostering advancements in stem cell therapy.

Therefore, this Special Issue aims to compile articles and reviews addressing the current obstacles, limitations, and side-effects that impede progress in the field, as well as potential strategies and solutions to overcome these issues.

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. Biomedicines is an international peer-reviewed open access monthly 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 2600 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.

Background/Objectives: Endothelial cell (EC) culture relies on specialized and commercial media with distinct growth supplement compositions. These media are expensive and must be imported, increasing the time to effective use. Human platelet lysate (PL) and platelet lysate serum (PLS) supplemented media are emerging alternatives to commercial media. Methods: Umbilical cords were collected, and human umbilical vein endothelial cells (HUVEC) were isolated and cultured using different media formulations, using Endothelial Cell Growth, Promocell® (ECGM-Promocell®) commercial medium, and media supplemented with PL and PLS. Results: A mixed medium combining DMEM-F12 + PLS and ECGM-Promocell® maintained EC viability, adhesion, and proliferation. Introducing a PL-derived protein substrate enhanced cell adhesion and proliferation by simulating an extracellular matrix. Flow cytometry revealed positive CD31, CD144, and CD146 markers in cells cultured with ECGM-Promocell® and the mixed medium, with or without the PL-protein substrate. Conclusions: These findings suggest that the mixed medium, especially with the PL protein substrate, offers a cost-effective and efficient approach for EC culture and proliferation, holding promise for research and therapeutic applications.
