Furthermore, additional markers can further strengthen the characterisation. Taken together, these results suggested that ADSC transplantation could improve endometrial injury as a novel therapy for IUA.

Lu, Xin For practical purposes, cells should be available as an off-the-shelf product immediately upon demand at the point of care [73]. Moreover, clinical safety and efficacy studies should be performed before further clinical use, in order to avoid any adverse effects connected with cell-based therapies. Guidelines for immunophenotypic characterisation of ASCs and SVF are summarised in Table 2. A number of factors currently limit the sharing of data, including ethical regulations concerning the use of human cell lines, the complexity of the landscape of intellectual property rights, and the potential competitive spirit of individual scientists [216]. One approach to replace FBS from cell culture is to use human platelet-derived supplements [23]. Cell-based therapies are a novel approach to treat medical conditions that have limited or no effective therapeutic options. Cancer treatments generally rely on tumour destruction techniques that may lead to major functional defects in surrounding tissues [181]. Mimmi Patrikoski, Bettina Mannerström, Susanna Miettinen, "Perspectives for Clinical Translation of Adipose Stromal/Stem Cells", Stem Cells International, vol. Until recently, stem cell research conducted within academic settings has paid no or little attention to patent questions.

Gomperts, J. Moreover, different cell donors have significant variations in the composition of their secretomes and the immunomodulatory capacity of their cells, which may lead to highly variable clinical outcomes. Clinical trials for ASCs are described below in more detail. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Additionally, Katz et al.’s patent included the secreted hormones and conditioned media of ASC cultures, as well as the production of an extracellular matrix lattice from adipose tissue.

This particular patent was broad and covered the cells both alone and within biologically compatible materials, as well as the methods used to generate differentiated tissues and structures, both in vivo and in vitro. Moreover, cell dose may depend on the administration method, i.e., whether cells are locally carried to the defect site on a scaffold or infused into the bloodstream, in which case the cell dose is often estimated in relation to patient weight. The term “substantial manipulation” denotes that the biological characteristics, functions, or properties relevant for the therapeutic effect have been altered [208]. Thus, optimisation of in vivo models is critical for the successful development of cellular therapies [144]. Celution® system is an example of a patented technology that has been developed for clinical use to facilitate automated processing of ASCs in a functionally closed system [215].

In conclusion, allogeneic ASC-based therapy faces significant challenges, but autologous ASC-based therapy is not without problems [75]. The search results are summarised in Table 4. MSC-mediated immunosuppression includes both soluble factors and direct cell-cell contacts, and additionally, the local cellular environment influences the immune plasticity of MSCs [94–97]. Copyright © 2019 Mimmi Patrikoski et al. Importantly, unlike the human bone marrow stromal/stem stem cells (BMSCs) that are present at low frequ … However, batch-to-batch variation between serum-supplemented media affects the proliferation rate and differentiation capacity of the cells [56]. McIntosh and coworkers demonstrated that the immunogenicity of ASCs decreases with cell passaging, and SVF may remain more immunogenic compared to cells at higher passages [3]. Alizadeh, Zohreh The original patent that covers ASCs was published in 2004 by Katz and coworkers [217].
