Preadipocytes are precursor cells that develop into adipocytes when fully differentiated. Adipocytes perform essential functions of energy metabolism and are characterized by the accumulation of intracellular triglycerides.

Preadipocyte Cells are isolated from subcutaneous or visceral fat. Subcutaneous fat is often found attached to skin in the lower abdomen area. Visceral preadipocytes are isolated from adipose tissue associated with internal organs, such as the bladder or kidney.

Relative to subcutaneous fat, visceral fat deposits are mobilized at a higher rate to produce serum fatty acids which contribute to insulin resistance, Diabetes Type 2, and other related cardiovascular disorders.

Diabetes mellitus type 1 (Type 1 diabetes, IDDM, or, formerly, juvenile diabetes) is a form of diabetes mellitus that results from autoimmune destruction of insulin-producing beta cells of the pancreas. It can be treated with Insulin injections.
