Adipogenesis

Federal government websites often end in, adipogenesis. The site is secure. The formation of adipocytes during embryogenesis has been largely adipogenesis.

Adipogenesis is the formation of adipocytes fat cells from stem cells. Determination is mesenchymal stem cells committing to the adipocyte precursor cells, also known as lipoblasts or preadipocytes which lose the potential to differentiate to other types of cells such as chondrocytes , myocytes , and osteoblasts. Adipocytes can arise either from preadipocytes resident in adipose tissue, or from bone-marrow derived progenitor cells that migrate to adipose tissue. Adipocytes play a vital role in energy homeostasis and process the largest energy reserve as triglycerol in the body of animals. This process is highly regulated by counter regulatory hormones to which these cells are very sensitive.

Obesity is now a widespread disorder, and its prevalence has become a critical concern worldwide, due to its association with common co-morbidities like cancer, cardiovascular diseases and diabetes. Adipose tissue is an endocrine organ and therefore plays a critical role in the survival of an individual, but its dysfunction or excess is directly linked to obesity. The journey from multipotent mesenchymal stem cells to the formation of mature adipocytes is a well-orchestrated program which requires the expression of several genes, their transcriptional factors, and signaling intermediates from numerous pathways. Understanding all the intricacies of adipogenesis is vital if we are to counter the current epidemic of obesity because the limited understanding of these intricacies is the main barrier to the development of potent therapeutic strategies against obesity. Since AMPK promotes the development of brown adipose tissue over that of white adipose tissue, special attention has been given to its role in adipose tissue development in recent years. In this review, we describe the molecular mechanisms involved in adipogenesis, the role of signaling pathways and the substantial role of activated AMPK in the inhibition of adiposity, concluding with observations which will support the development of novel chemotherapies against obesity epidemics. Obesity is an increasingly prevalent disorder around the globe promoted by genetic, nutritional, and environmental factors. Energy imbalance — excessive consumption of calories compared to utilization is the key driving force of obesity. Obesity is a multifactorial chronic disease, linked to other disorders including cancer, insulin resistance, cardiovascular diseases and type-2 diabetes Cohen et al. There are many factors which contribute to obesity such as sedentary lifestyle, high calorific intake, depression, and various social and monetary issues, but they have a single common result: the accumulation of fats in mature adipocytes of white adipose tissue WAT : obesity is characterized by increase in the mass of adipose tissue Ghaben and Scherer, Improved and holistic knowledge of the processes governing adipogenesis is required if we are to counter the burgeoning epidemic Rosen and MacDougald, Adipose tissue plays an important proper role in the body. Obesity is diagnosed either on the amount of WAT or the number of mature white adipocytes in WAT Park, , rather than simply by body weight.

There are two main types of adipose tissues in mammals; white and brown adipose tissues WAT and BATcharacterized by different morphologies, anatomical locations, biochemical features, adipogenesis, functions and gene expression patterns. Insulin adipogenesis adipogenesis through insulin-like growth factor 1 IGF1 receptor signaling. Fajas L.

Obesity is characterized by increased adipose tissue mass and has been associated with a strong predisposition towards metabolic diseases and cancer.

With the increase of population aging, the prevalence of type 2 diabetes T2D is also rising. Aging affects the tissues and organs of the whole body, which is the result of various physiological and pathological processes. Adipose tissue has a high degree of plasticity and changes with aging. Aging changes the distribution of adipose tissue, affects adipogenesis, browning characteristics, inflammatory status and adipokine secretion, and increases lipotoxicity. These age-dependent changes in adipose tissue are an important cause of insulin resistance and T2D. Understanding adipose tissue changes can help promote healthy aging process.

Bost F. MSCs become committed to the adipocyte lineage and lose their ability to differentiate into other cell types osteocytes, chondrocytes, myocytes etc. Wnt10a and Wnt10b, members of the canonical pathway, are the possible endogenous inhibitors of BAT. A combination of five metabolic risk factors: high blood pressure, elevated fasting blood glucose, hypertriglyceridaemia, decreased serum high-density lipoprotein and increased abdominal adiposity, which collectively increase the risk of heart disease, diabetes and stroke. White adipocytes or white fat cells are lipid-laden cells within WAT that acquire the ability to accumulate lipids after differentiation — the process in which the cells from a common ancestor are derived mitotically and become different from one another in morphology and function.

The formation of adipocytes during embryogenesis has been largely understudied. Adipogenesis consists of two phases, namely commitment and terminal differentiation.

Several studies have demonstrated autophagy in lipophagy, glycophagy, adipose tissue differentiation and mass regulation Singh et al. Booth, A. Sanders B. Therefore, transcription factors are crucial for adipogenesis. This may indicate that SREBP-1c expression is not critical for adipogenesis and adipose tissue development. Chung, Y. Takahashi N. Tung, Y. Myogenic gene expression signature establishes that brown and white adipocytes originate from distinct cell lineages. Earlier studies showed that GH exerts a dual effect on 3T3-FA preadipocytes, in which there is an initial direct effect on preadipocytes to initiate the adipogenic program that is followed by an indirect effect of GH to induce insulin-like growth factor-1 IGF-1 to stimulate growth of the committed cells Green et al.
