Human Adipose Tissue Derived Stem Cells (hADSCs) hADSCs or fat stem cells are isolated form fat obtained through liposuction which is a minimally invasive clinical procedure. Stem cells constitute nearly 2% of the human adipose tissues cell population. This makes fat the most versatile source of stem cells. Fat stem cells can be expanded very efficiently to produce substantial amounts of stem cells for clinical application. Fat stem cells can be cryopreserved (preserved by freezing) in a stem cell bank for later use. Frozen fat stem cells can be thawed and expanded through tissue culture again and again. Fat stem cells are multipoint and can differentiate into many other tissue specific cells. Once transplanted into the body, they simply differentiate in response to cues from damaged tissues and do not give rise to tumours.
