SANCHEZ, JULIO CÉSAR et al. The adipocyte in the laboratory: history, perspectives and report of experience. CES Med. [online]. 2015, vol.29, n.2, pp.271-282. ISSN 0120-8705.

Introduction: The human adipose tissue is composed of different cell types. It has been subject of several studies in the past years due to its role on diverse functions. Methods: A search in the PubMed, Scielo, Science direct and Google Scholars databases was performed and the authors experience was reported. Results: The first model used was rodent fat, which allowed a better comprehension on carbohydrate and fatty acid metabolism and enhanced research in adipocyte cell biology in addition with histological studies and mature adipocyte isolation. Afterwards, learning about precursor cell (pre-adipocytes) promoted the isolation of murine 3T3-L1 cell line. In Latin America research has been conducted using cell lines and adipocyte precursor mesenchymal stem cells to describe effects of hormones and perform DNA sequencing. In Colombia, studies in 3T3-L1 cell line aimed to stablish the effects of different compounds on these cells. In the Cell Physiology Laboratory of the Universidad Tecnológica de Pereira, sample collection process has shown difficulties because the source was human tissue; nevertheless isolation and cell culture protocols were standardized throughout the last six years of experimentation. Pre-adipocytes and mature adipocytes were isolated to study the effects of hormones, perform electrophysiological characterization and study calcium physiology. Conclusions: This is a relevant research field since these cells have important systemic metabolic functions and they have a clear relationship with high-prevalence pathologies such as obesity and the metabolic syndrome.
