Abstract
Obesity is a serious medical condition worldwide, which needs new approaches and recognized international consensus in treating diseases leading to morbidity. The aim of this review was to examine heterogeneous links among the various phenotypes of obesity in adults. Proteins and associated genes in each group were analysed to differentiate between biomarkers. A variety of terms for classification and characterization within this pathology are currently in use; however, there is no clear consensus in terminology. The most significant groups reviewed include metabolically healthy obese, metabolically abnormal obese, metabolically abnormal, normal weight and sarcopenic obese. These phenotypes do not define particular genotypes or epigenetic gene regulation, or proteins related to inflammation. There are many other genes linked to obesity, though the value of screening all of those for diagnosis has low predictive results, as there are no significant biomarkers. It is important to establish a consensus in the terminology used and the characteristics attributed to obesity subtypes. The identification of specific molecular biomarkers is also required for better diagnosis in subtypes of obesity.

Abstract
In this report, we introduce a standard protocol for stem cell self-renewal in vitro. Both fundamental and major procedures of stem cell manipulation, which are required for somatic cell coculture and self-renewal, are briefly described since they are important for stabilization and data normalization. In this chapter, information on the basic preparation of stem cell culture such as labware washing, equipment sanitization, microbe control, and mycoplasmosis prevention is provided. In addition, protocols for cell retrieval and preservation, proliferation assays, and basic manipulation techniques for the coculture of stem cells with somatic cells are described.
