Adipose-Derived Stem Cells: Methods for Isolation and Applications for Clinical Use

With accelerating rates of obesity and type 2 diabetes world-wide, interest in studying the adipocyte and adipose tissue is increasing. Human adipose derived stem cells - differentiated to adipocytes in vitro - are frequently used as a model system for white adipocytes, as most of their pathways and functions resemble mature adipocytes in vivo. However, these cells are not completely like in vivo mature adipocytes. Hosting the cells in a more physiologically relevant environment compared to conventional two-dimensional cell culturing on plastic surfaces, can produce spatial cues that drive the cells towards a more mature state. We investigated the adipogenesis of adipose derived stem cells on electro spun polycaprolactone matrices and compared functionality to conventional two-dimensional cultures as well as to human primary mature adipocytes.

Adipose-Derived Stem Cells

Metrics details. Adipose-derived stem cells ADSCs have raised big interest in therapeutic applications in regenerative medicine and appear to fulfill the criteria for a successful cell therapy. Their low immunogenicity and their ability to self-renew, to differentiate into different tissue-specific progenitors, to migrate into damaged sites, and to act through autocrine and paracrine pathways have been altogether testified as the main mechanisms whereby cell repair and regeneration occur. Also, comparisons across pooled patients are particularly difficult in the fact that multiple medical devices are used and there is absence of harmonized assessment assays despite meeting regulations agencies and efficient GMP protocols. Moreover, the emergence of the COVID breakdown added to the complexity of implementing standardization. Cell- and tissue-based therapies are completely dependent on the biological manifestations and parameters associated to and induced by this virus where the scope is still unknown. The initial flow chart identified for stem cell therapies should be reformulated and updated to overcome patient infection and avoid significant variability, thus enabling more patient safety and therapeutic efficiency.

Mesenchymal stem cells MSCs have the capacity for multi-lineage differentiation, giving rise to a variety of mesenchymal phenotypes such as osteoblasts bone , adipocytes fat , and chondrocytes cartilage. Stem cell therapy holds immense promise of delivering the next generation of future medical breakthroughs. In this respect, multipotent progenitor cells, such as hMSCs, have attracted high clinical interest because of their ability to differentiate into various cell types and their immunoregulatory properties. Together, these features enable the allogeneic use of hMSCs and thus make them an attractive target for commercial therapeutic development. Browse all Mesenchymal Stem Cell Products.

Compared with mesenchymal stem cells MSCs derived from other tissues such as umbilical cord and bone marrow, isolation of ASCs from human white adipose tissue WAT has great advantages due to its rich tissue source and simple surgical procedure. Molecular characterization of isolated ASCs was performed through surface marker expression profiling using flow cytometry. Adipogenic capacity of the isolated ASCs was confirmed through inducing adipogenic differentiation and Oil Red O staining of lipid. This protocol provides researchers with the tools to culture and assess purity and adipogenic differentiation capacity of human ASCs, which can then be utilized for required downstream in vitro applications. This protocol has been modified from Baglioni et al. The isolated human ASCs show high purity and demonstrate adipogenic differentiation capacity in vitro. Human ASCs are an invaluable in vitro cell model to study molecular pathways important for the etiology of metabolic diseases, including obesity and type 2 diabetes.

This second edition volume expands on the previous edition with a comprehensive update Methods and Protocols Isolation of Murine Adipose-​Derived Stromal/Stem Cells for Adipogenic Differentiation or Flow Cytometry-​Based Analysis.

Mesenchymal Stem Cell Culture Protocols

Protocol DOI: Adipose tissue sciences have rapidly expanded since the identification of regenerative cells contained within the stromal vascular fraction SVF of fat. Isolation of the SVF, containing adipose-derived stem cells ADSC , can be accomplished efficiently in the operating room or in the laboratory through enzymatic digestion of the adipose tissue and concentration of SVF. Cells can be directly re-injected as a mesotherapeutic agent, recombined with a tissue scaffold e. The potential for cell therapy is under current investigation by researchers around the world.

Manuscripts that exploit pharmacological, physiopathological and diagnostic aspects related to percutaneous intervention in cardiovascular diseases are also considered for publication. Although other disciplines present aspects somehow related to this specialty, it is not the intention of RBCI to publish manuscripts related to electrophysiology or to heart surgery. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact.

Adipose-Derived Stem Cells in Tissue Regeneration: A Review

Methods and Protocols

In , researchers at the University of California, Los Angeles, described the isolation of a new population of adult stem cells from liposuctioned adipose tissue. These stem cells, now known as adipose-derived stem cells or ADSCs, have gone on to become one of the most popular adult stem cells populations in the fields of stem cell research and regenerative medicine. As of today, thousands of research and clinical articles have been published using ASCs, describing their possible pluripotency in vitro, their uses in regenerative animal models, and their application to the clinic. This paper outlines the progress made in the ASC field since their initial description in , describing their mesodermal, ectodermal, and endodermal potentials both in vitro and in vivo, their use in mediating inflammation and vascularization during tissue regeneration, and their potential for reprogramming into induced pluripotent cells. These cells, initially characterized in the journal Tissue Engineering, were named as such due to their derivation from processed lipoaspirate tissue obtained through cosmetic surgery. Zuk et al. The SVF has been defined as a minimally processed population of red blood cells, fibroblasts, endothelial cells, smooth muscle cells, pericytes, and preadipocytes that have yet to adhere to a tissue culture substrate [ 2 , 3 ].
